Revolution Pi Analog I/O expansion module (RevPi Analog I/O)

Description:

Using the analog I/O - module RevPi AIO your RevPi base module can be expanded by 4 analog inputs, 2 analog outputs and 2 RTD input channels. This expansion module is connected to your base module by the means of the overhead PiBridge plug. Inputs, RTD inputs and outputs are galvanically isolated to each other. Differential inputs eliminate ground loops.

Analog input range/options: +/- 10 V, 0 – 10 V, 0 – 5 V, +/- 5 V, 0 – 20 mA, 0 – 24 mA, 4 – 20 mA, +/- 25 mA

Analog outputs range/options: 0 – 5 V, 0 – 10 V, +/- 5 V, +/- 10 V, 0 – 5,5 V, 0 – 11 V, +/- 5,5 V, +/- 11 V, 4 – 20 mA, 0 – 20 mA, 0 – 24 mA

The 2 RTD inputs enable temperatures to be measured with high precision from -165°C to +600°C in steps of 0.5°C using common RTDs sensors like Pt100/Pt1000 probes. The probes can be connected directly to the module with 2, 3 or 4 cables.

Just like the digital IO modules, RevPi AIO is protected against disturbances according to EN61131-2 and can be operated between -40 and +50°C ambient temperature and up to 80% relative humidity. It is also protected against static discharges, burst and surge impulses in accordance with EN61131-2 requirements.

The required PiPridge Plug (Item No.: 100204) and a set of 14-pole PCB female connectors (Item No.: 200030) are already included in the scope of delivery of this expansion module.

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

Learning to solder LED kit Pack of 25 (KT begin solder bundle)

 

Our learn to solder pack is the ideal low cost solution for teaching soldering in the classroom/after school club. The pack provides all of the parts and PCB's required for a class size of 25 and also includes a 9V battery for testing purposes. Each pack comprises; 25 x PCBs, 100 x 100 ohm resistors, 25 x LED's, and a 9V PP3 battery.

We have also produced a step by step guide to soldering, which covers; equipment, solder, tinning & cleaning, soldering in 8 steps, de-soldering in five steps, wire preparation, examples of good and bad solder joints, basic PCB repair, resistor information, LED information, full step by step build information for the kit, and how the learn to solder kit works. This guide covers everything that you might need to discuss with students and can form the basis of your lesson plan.

Using the kits and the step by step guide, each student will solder four resistors and one LED to their PCB before pressing it to the terminals of the 9V battery to check that their board works. Using the guides they will be able to examine their own work and troubleshoot problems. The battery pads on the PCBs have been shaped inline with the battery terminals on a PP3 battery making it straightforward to see which way around it should be placed on the battery.

Features

  • Purpose built PCBs that can be tested, once built, with the supplied 9V PP3 battery.
  • Low cost classroom pack for 25 students.
  • Easy build kit.
  • Full teaching resources and step by step guides available for this kit below.

What's in the box?

100 x 100 ohm Resistors.
