Ray reports he’s just finished working on a new open source wearable electronics controller board called SquareWear. It’s small (1.6″x1.6″) and has built-in USB port (used for programming the microcontroller, USB serial communication, and charging battery). It also has 4 on-board MOSFETs for switching high-current load (up to 500mA). The board is based on Microchip’s PIC18F14k50, and includes a SquareWear library to make it as easy to use as Arduino. Check out RaysHobby website for the source code and programming guide.
