VGA 666 Adapter Board For Raspberry Pi 3 Model B 2B B+ A+ (vga board red soldered)
Description:

It is a neat and very useful solution for using a VGA display/monitor with your Raspberry Pi and is cheaper than an HDMI to VGA adapter or similar. The VGA connection is driven natively in hardware over the GPIO pins (using a parallel interface) and uses around the same CPU load as the HDMI connection on board. It is capable of displaying 1080p60 VGA video with no CPU load. It is also possible to drive this interface at the same time as the HDMI connection, so a dual screen set up is also possible.

This add-on board uses all but 6 of the GPIO pins so it may not be possible to use other add-on boards at the same time as the VGA adapter. You should disable all of the GPIO pin's function so that it can work properly.

We strongly recommend that you use 800x600 resolution. Higher resolution will slow down your Pi and use more RAM.

Features:

- Support for Raspberry Pi 3B / 2B / B+ / A+
- The VGA output supports resolution:from 640 x 480 up to 1920 x 1024 at 60fps.
- With 6 bits per channel you have a maximum of 262144 colours.
- No soldering required.
- Easy to setup.
- Easy to configure.
- Dimension: 64.00mm x 32.3mm
- Net weight: 16.5g

SparkFun Logic Level Converter Bi-Directional (Sparkfun logic level converter )

If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time.

This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.

The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.

Adafruit ADS1015 12-Bit ADC (ADS1015 12-Bit ADC)

The Raspberry Pi does not feature an Analog-to-Digital Converter (ADC), so if you want to measure analogue singals, you'll need this 12-Bit ADC!

The Adafruit 4-Channel I2C 12-Bit ADC is a high-precision ADC and features the ADS1015 chip, which provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier,with up to x16, to help boost smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter. 

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet and interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5 in downloads below) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs. 
 
To get you started, we have example code for the Raspberry Pi - Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.
 
The Adafruit 4-Channel I2C 12-Bit ADC Features:
  • Wide Supply Range: 2.0V to 5.5V
  • Low Current Consumption: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-Down
  • Programmable Data Rate: 128SPS to 3.3kSPS
  • Internal Low-Drift Voltage Reference
  • Internal Oscillator
  • Internal PGA
  • I2C Interface: Pin-Selectable Addresses
  • Can run from 2V to 5V power/logic
  • Measures a large range of signals and is super easy to use.
  • 12-bit precision at 3300 samples/second over I2C.
  • Configurable as 4 single-ended input channels, or two differential channels.
  • Includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range.
  • Breakout Board equipped with ferrites to keep the AVDD and AGND quiet

Pi Stop - Traffic Light Add-on for Raspberry Pi (GPIO 3.3V stand traffic light)

The Pi-Stop is a low cost hardware module designed to allow Raspberry Pi users to take their first steps into interfacing with the real world.

Designed with the learning in mind, everyone will recognise and identify its familiar elements encouraging their use along-side their own projects.

Move past the Stop light

The Pi-Stop is designed to remove many of the common hurdles people are faced with when getting started using hardware with the Raspberry Pi. Often it is difficult to know what components to use and how to connect them, the Pi-Stop makes it simple by plugging directly onto pre-set positions on the Raspberry GPIO connector.

By plugging the Pi-Stop directly on to the Raspberry Pi GPIO header, no extra cables or wires are needed. Unlike many other add-on boards, they do not block unused GPIO pins, keeping them open for other uses. The Pi-Stop can be fitted in 4 standard locations, allowing up to four Pi-Stops to be controlled independently or combined with other hardware.

Prepare to go!

The Pi-Stop provides a simple stepping stone, between pure screen based programming and using physical hardware to interact with the real world. Components like the Pi-Stop will provide a flexible and non-restrictive way to build understanding through experimenting.

Since it is only a step away from a bag of components, it also allows the programming of hardware to be introduced, and the electronics involved can be introduced separately, if desired. Allowing the pupils to discover they can control real things, and then again to discover they can also build their own circuits and control them in exactly the same way.

Often, people are faced with a magic board which they plug in and tell it to do stuff, however it isn't always clear to them why or how it does it. By providing something which they can remove and replace with something (apparently) completely different (- wires, breadboards and LEDs) they will be able to understand the link.

By keeping the hardware very simple, it allows better understanding of what is happening, and allows space to come up with your own projects and apply the concepts with your own ideas in mind.

GO Full throttle

The documentation and guides are openly available for the Pi-Stop for educational use. There will be guides, tutorials and workshop material available all of which can be taken as is[available as PDF format] or adapted to your own needs [available in markdown format].

It is encouraged that similar materials can be submitted back for others also to share and make use of.

The materials will demonstrate the concepts, methods and provide the building blocks to explore ideas and take learning further by with creative projects, activities and games.

Adafruit 12-Bit DAC w/I2C Interface (MCP4725) (AdaMCP4725 DAC)

Your microcontroller probably has an ADC (analog -> digital converter) but does it have a DAC (digital -> analog converter)??? Now it can! This breakout board features the easy-to-use MCP4725 12-bit DAC. Control it via I2C and send it the value you want it to output, and the VOUT pin will have it. Great for audio / analog projects, such as when you can't use PWM but need a sine wave or adjustable bias point.

The ADDR pin is broken out so you can connect two of these DACs on one I2C bus, just tie the ADDR pin of one high to keep it from conflicting. Also included is a 6-pin header, for use in a breadboard. Works with both 3.3V or 5V logic.

Some nice extras with this chip: for chips that have 3.4Mbps Fast Mode I2C (Arduino's don't) you can update the Vout at ~200 KHz. There's an EEPROM so if you write the output voltage, you can 'store it' so if the device is power cycled it will restore that voltage. The output voltage is rail-to-rail and proportional to the power pin so if you run it from 3.3V, the output range is 0-3.3V. If you run it from 5V the output range is 0-5V.

Adafruit have an easy-to-use Arduino library and tutorial with a triangle-wave and sine-wave output example that can be used with any 'duino or ported to any microcontroller with I2C host. Wiring it up is easy - connect VDD to your microcontroller power pin (3-5V), GND to ground, SDA to I2C Data (on the Arduino Uno, this is A4 on the Mega it is 20 and on the Leonardo digital 2), SCL to I2C Clock(on the Arduino Uno, this is A5 on the Mega it is 21 and on the Leonardo digital 3) and listen on VOUT.

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

RASPBERRY PI BOARD NOT INCLUDED

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
