Introduction
The Igloo: PICAXE wearable module has been designed specifically for use in E-textiles projects and provides a cost
effective, fun way to learn about electronics and programming in a textiles environment.
The board uses a PICAXE14M2 microcontroller. This is a chip that can be programmed using the free PICAXE
Programming Editor software to respond to various inputs like switches and sensors and control outputs like LEDs or
buzzers.
This guide will provide all the information you need to get started with the Igloo PICAXE wearable module.

  • Page 2 Hardware The Igloo PICAXE wearable module has 6 I/O pins. The three on the left (C.4, C.1 and C.0) have pull-down resistors on the board. This means you can attach a switch between the “+” pad at the top or bottom of the board and any of those inputs and have a switch which goes high when closed and low when opened.

  • Page 4 Power There are several ways you can power your Igloo PICAXE wearable module: 1) The simplest way is with a 2xAAA alkaline batteries in a battery cage with JST connector. Zinc carbon or rechargeable NiMH batteries will not work well as they drop in voltage very quickly, meaning any LEDs attached will start to dim.
  • Page 5 Igloo: PICAXE wearable module Starter Guide www.kitronik.co.uk Important: To program the board you will need a USB PICAXE Programming Cable (available here). You will also need the correct software. Download the latest version of the PICAXE Programming Editor, our quick start page has a link.
  • Page 6 Check the programming cable is fully inserted into the Igloo PICAXE wearable module and that the board has a power supply attached then click the “Program” icon near the top of the screen. A green progress bar will appear at the bottom right of the screen and it will inform you when the code has successfully been uploaded.

    Igloo: PICAXE wearable module Starter Guide www.kitronik.co.uk Connecting Components There are two ways to connect the PICAXE Control Board to your other e-textiles components. Using Crocodile Clips The fastest way to do this is by using crocodile leads. It is a good idea to test your circuit this way before sewing it into a project as it is much easier to make changes if your circuit is incorrect.
