The Wombat board helps you create electronic projects that connect to your Raspberry Pi, whether you're designing a new product or just playing.

It's all about prototyping - taking an idea and seeing what you can do with it!

What does it do?

It provides useful facilities for building your creations, including:

  • all of the Raspberry Pi's GPIO pins are made easily accessible and clearly labelled
  • 8 x analog inputs
  • USB serial console and power connection
  • a large solderless breadboard that doesn't limit you to small, simple projects
  • 2 x pushbuttons, 4 x LEDs and a trimpot
  • all on a convenient, sturdy platform supported by a set of six rubber feet

that are really helpful when working on a design or playing around with ideas.

What else does it do?

One of the challenges with building circuits that work with a Raspberry Pi is that, although its GPIO pins use 3.3 V logic, it can only supply up to 50 mA at 3.3 V, which may not be enough to power your circuit. The Wombat board helps to overcome this limitation by incuding a 3.3 V power supply that can supply up to 500 mA.

And wouldn't it be nice to be able to connect to the Raspberry Pi's serial console via USB? You could then log in and use it without a network connection, configure the network (including WiFi), find out what IP address its using, or simply watch the messages scroll past while it boots. And wouldn't it be nice to be able to use that USB connection to also power your Raspberry Pi? The Wombat board makes of that possible by providing a micro USB port and a genuine FTDI serial to USB bridge that not only provides access to the Raspberry Pi's serial console, but can power the Raspberry Pi and Wombat board as well.

Or not - each of the Wombat board's functions can easily be disabled if your project doesn't need it.

It works with the newer Raspberry Pi models which include a 40-pin GPIO header, such as the A+, B+, and the new Raspberry Pi 2, as well as compatible single-board computers such as the Banana Pro and Banana Pi M1+.

What do you get?

The Wombat board is supplied fully built and comes with:

  • a 40-pin IDC cable to connect it to your Raspberry Pi
  • extra components inlcuding an RGB LED, a temperature sensor and a photocell for use with the example projects
  • a small set of breadboard jumper wires to get you started
  • a comprehensive manual, including schematics
  • a Python module for using the board's features, incuding the analog inputs, from your Python programs - fully documented and with example code provided
  • introductory projects, including a temperature-controlled colour-changing LED, all fully documented with source code provided

You can see those projects in action in thise videos:

Features:

  • All 40 Raspberry Pi (2, A+ or B+) GPIO pins broken out to a clearly labelled and easily accessible 40-pin header
  • Onboard 3.3 V voltage regulator, supplying up to 500 mA to your circuit
  • 8 x 10-bit analog inputs, via an analog-to-digital converter (MCP3008) connected to the Raspberry Pi's SPI bus
  • All signals conveniently made available alongside a large solderless breadboard, for convenient custom circuit development
  • 2 x pushbuttons to use as digital inputs
  • 4 x LEDs to use as digital outputs
  • 1 x potentiometer to use as a basic analog input
  • All onboard I/O devices are clearly labelled with both "BCM" and "Board" numbering schemes
  • USB to serial bridge (genuine FTDI FT232), connecting the Raspberry Pi's serial pins to a standard micro USB port
  • Able to power the Raspberry Pi via the console USB port - just one standard micro USB cable providing power and connectivity!
  • All onboard devices can be disconnected or disabled via jumpers - if you don't need a facility, simply take it out of circuit
  • 6 x rubber feet (already installed)
