PUD Board (Pull-Up/Down Resistor Board) (MMP PUD board)

RASPBERRY PI BOARD NOT INCLUDED

Description:

Whether you're pulling-up or pulling-down, there's no need to frown! With the PUD board from ModMyPi, adding multiple pull-up or pull-down resistors to your Raspberry Pi project is easy!

If you want to detect an "output" with your Raspberry Pi, like a button being pressed or a motion sensor detecting movement, we can configure our Raspberry Pi's GPIO pin as an "input". That input pin can be in three states (known as Tri-State logic); "high", when 3.3V is applied, "low", when the pin is connected to 0V, and "floating" when the state is undefined. Floating voltages are troublesome in electronics as the input can either read high or low depending on various fluctuations in electrical noise. Like a gate flapping open and closed in the wind, someone needs to lock the gate closed, or wedge it open. If you leave it flapping, it's likely to hit someone on their bottom on the way through!

Like our gate, the best way to avoid a floating input is to "tie" your input pin either high or low to create a default state. This is usually achieved through the use of a pull-up or pull-down resistor, either connecting our input pin via a resistor to the Pi's 3.3V to achieve a 3.3V high state, or the GND line to achieve 0V low state.

Our PUD board takes the messy wiring out of adding a pull-up or pull-down resistor to your circuit. Simply wire up the sensor output to the single pin on the PUD board and add a shunt jumper to either pull up (u) or down (d)! Therefore when you apply a signal voltage from your sensor or switch, the Pi is easily able to sense into which logic state the pin has been pulled! No more trouble from floating I/O's!

The PUD boards connects across GPIO pins 11 to 18 (17 to 24 in BCM speak), and adds a jumper configurable pull-up or pull-down resistor to each GPIO pin: 11 (BCM 17), 12 (BCM 18), 13 (BCM 27), 15 (BCM 22), 16 (BCM 23) and 18 (BCM 24). Pin 17 (3.3V) & pin 14 (GND) are used to tie the pins!

The PUD Board Features:

  • Add a pull-up or pull-down resistor to your GPIO with the swap of a jumper!
  • Compatible with all Raspberry Pi Models Inc. A /B /2/3 & Zero/ZeroW
  • Tiny board means it's easy to integrate into any circuit - takes up just 8 GPIO pins
  • Connects across GPIO pins 11 to 18 inclusive (BCM 17 to 24)
  • In-line 1kΩ current limiting resistors on each GPIO
  • 10kΩ pull-up or pull-down resistors on each GPIO
  • All 6 GPIO pins can be configured independently 
  • Includes 6 x 2 Pin Shunt Jumpers & 1 x PUD Board
  • Jumper configurable pull-up or pull-down resistor on pins:
    • 11 (BCM 17)
    • 12 (BCM 18)
    • 13 (BCM 27)
    • 15 (BCM 22)
    • 16 (BCM 23)
    • 18 (BCM 24).
  • Pin 17 (3.3V) & Pin 14 (GND) are used to tie the pins!
  • To pull pin up, connect the jumper across "u" and the center pin
  • To pull pin down, connect the jumper across "d" and the center pin

PiStep2 Quad Stepper Motor Control Board for Raspberry Pi (PiStep2 stepper hat)
Description:

This neat little board plugs directly into the Raspberry Pi GPIO header and provides 2 or 4 connectors for small stepper motors

  • Fully Assembled - No Soldering Required
  • Raspberry Pi Zero Form Factor - works with all versions of Raspberry Pi with 40pin GPIO connector
  • Stepper motors and Raspberry Pi not included

Various Power Options:

  1. Powered from the Raspberry Pi 5V
  2. From the 2-pin Terminal (whatever voltage is required for the motors)
  3. Micro-USB - 5V only

Pinout is simple:

  • Physical pins 11, 12, 13, 15 for Motor A (GPIO 17, 18, 27, 22)
  • Physical pins 16, 18, 22, 7 for Motor B (GPIO 23, 24, 25, 04)
  • Physical pins 33, 32, 31, 29 for Motor C (GPIO 13,12,6,5)
  • Physical Pins 38, 37, 36, 35 for Motor D (GPIO 20,26,16,19)

Each pin has an associated white LED so you can see the stepper signals going through

Power Supply Alternatives

  • Jumper VCC-VSTP (default). Power from the motors is taken from the Raspberry Pi 5V line
    • Micro-USB into Raspberry Pi. 5V for the Pi and the stepper motors goes through a poly-fuse which can trip if 2 motors are used simultaneously
    • Micro-USB into the PiStep board. 5V for both the Pi and the stepper motors is provided directly from the 5V USB input so no problems with 2 motors at once
  • Jumper VSTP-VIN. Power for the motors is provided from the 2-pin screw terminal, so can be any voltage that the steppers can handle. Ensure you use the correct polarity! We recommend to keep it below 12V. You will find that the stepper motors can go up to 9V and will be able to step faster, the higher the voltage that is applied, but there will be some deterioration of the life of the stepper motor at a higher voltage.

Python Programming

Please see the excellent example here for some pointers. You will need to change the pin numbers as above and also change the speed so it steps at a visible rate. You may also want to remove the print statements to speed it up. The lines in Red below are changed from the original to operate Motor A.

# Use BCM GPIO references
# instead of physical pin numbers
GPIO.setmode(GPIO.BCM)

# Define GPIO signals to use
# Pins 18,22,24,26
# GPIO24,GPIO25,GPIO8,GPIO7
StepPins = [17,18,27,22]

# Set all pins as output
for pin in StepPins:
  print "Setup pins"
  GPIO.setup(pin,GPIO.OUT)
  GPIO.output(pin, False)

# Define some settings
StepCounter = 0
WaitTime = 0.01

ScratchGPIO Programming

These pins are identical to those required by ScratchGPIO and therefore can easily be driven using simple Scratch commands:

Set motor type for Scratch to be Stepper motor

Set the position of the stepper motor A

Set the speed of the stepper motor A

ESP32-WROVER 4MB Module with Bluetooth and WiFi (ESP32-WROVER)
 Description:

ESP32-WROVER is a powerful, generic WiFi-BT-BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding. At the core of this module is the ESP32-D0WDQ6 chip*, same as ESP-WROOM-32 module. Compared to ESPWROOM-32, ESP32-WROVER has an additional SPI Pseudo static RAM (PSRAM) of 32 Mbits. As such, ESP32- WROVER features both 4 MB external SPI flash and 4 MB external PSRAM. The ESP32-WROVER module has a PCB antenna, while the ESP32-WROVER-I uses an IPEX antenna. The information in this datasheet is applicable to both of the two modules. The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled, and the clock frequency is adjustable from 80 MHz to 240 MHz. The user may also power off the CPU and make use of the low-power coprocessor to constantly monitor the peripherals for changes or crossing of thresholds. ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, low-noise sense amplifiers, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C.

The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted, and that the module is future proof: using Wi-Fi allows a large physical range and direct connection to the internet through a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection. The sleep current of the ESP32 chip is less than 5 µA, making it suitable for battery powered and wearable electronics applications. ESP32 supports a data rate of up to 150 Mbps, and 22 dBm output power at the antenna to ensure the widest physical range. As such the chip does offer industry-leading specifications and the best performance for electronic integration, range, power consumption, and connectivity. The operating system chosen for ESP32 is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that developers can continually upgrade their products even after their release.

Package includes:

1 x ESP32-WROVER 4MB Module

Enviro for Raspberry Pi (enviro sensor phat)
Description:

Monitor your world with Enviro for Raspberry Pi! There's a whole bunch of fancy environmental sensors on this board, and a gorgeous little full-colour LCD to display your data. It's the perfect way to get started with citizen science!

Designed for environmental monitoring, Enviro  lets you measure air quality (pollutant gases and particulates*), temperature, pressure, humidity, light, and noise level. When combined with a particulate matter sensor*, it's great for monitoring air quality just outside your house (more information below), or without the particulate sensor you can use it to monitor indoor conditions.

Enviro  is an affordable alternative to environmental monitoring stations that can cost tens of thousands of pounds and, best of all, it's small and hackable and lets you contribute your data to citizen science efforts to monitor air quality via projects like Luftdaten.

Features

  • BME280 temperature, pressure, humidity sensor (datasheet)
  • LTR-559 light and proximity sensor (datasheet)
  • MICS6814 analog gas sensor (datasheet)
  • ADS1015 analog to digital converter (ADC) (datasheet)
  • MEMS microphone (datasheet)
  • 0.96" colour LCD (160x80)
  • Connector only for particulate matter (PM) sensor*(sensor is not included)
  • pHAT-format board
  • Fully-assembled
  • Compatible with all 40-pin header Raspberry Pi models
  • Pinout
  • Python library
  • Dimensions: 65x30x8.5mm

A couple of nice little extras... there's a spare ADC channel broken out on a header if you want to connect another analog sensor, along with I2C pins in the right configuration for plugging one of our Pimoroni I2C breakouts onto!

Citizen science air quality monitoring

We've developed this board in collaboration with the University of Sheffield, with the aim of letting you contribute real-time air quality data from your local area to open data projects like Luftdaten.

The alarming drop in our air quality is something that's really important to understand. Devices like Enviro  allow fine-grained, detailed datasets that let us see shifts in air quality through time and across different areas of cities. The more devices that contribute data, the better quality the dataset becomes.

Particulate matter (PM) is made up of tiny particles that are a mix of sizes and types, like dust, pollen, mould spores, smoke particles, organic particles and metal ions, and more. Particulates are much of what we think of as air pollution. They can be measured, in size and quantity, by particulate matter sensors like the PMS5003 that you can connect to Enviro .

The analog gas sensor can be used to make qualitative measurements of changes in gas concentrations, so you can tell broadly if the three groups of gases are increasing or decreasing in abundance. Without laboratory conditions or calibration, you won't be able to say "the concentration of carbon monoxide is n parts per million", for example.

Temperature, air pressure and humidity can all affect particulate levels (and the gas sensor readings) too, so the BME280 sensor on Enviro  is really important to understanding the other data that Enviro outputs.

We've got a tutorial (coming soon) that shows you how to use Enviro  and a few easily-available bits to build the board into a weather-proof housing that you can mount outside your house to monitor local air quality.

Indoor monitoring

As well as outdoor air quality monitoring, Enviro  is really good for indoor monitoring too. The temperature, humidity, light, and noise readings can be used to keep track of conditions in your home and, combined with the LCD to display the data and the proximity sensor for interaction, it makes an ideal headless monitoring device.

Why not combine it with some IoT smarts like an Alexa skill so that you can ask what the temperature or humidity is? Or you could set up a trigger action with IFTTT that turns your Philips Hue lights on when the light level drops below a certain level. There's loads of possibilities!

Software

We've put together a Python library to control all the parts of your Enviro . There's a bunch of examples for each of the individual parts, an all-in-one example that shows you the data from Enviro 's sensors in a visual way. There's also an example that shows you how to contribute data to Luftdaten (requires particulate matter sensor).

Getting started

Have a read through our (exhaustive!) Getting Started with Enviro  tutorial that walks you through how to install the software, how to run the code examples, and how to use the Enviro  Python library.
