A Smart Bluetooth Button that can be programmed wirelessly

Puck.js is an intelligent Bluetooth button. With the Espruino JavaScript interpreter on its internal ARM microcontroller, software can be uploaded, debugged and modified wirelessly from any modern computer or phone, making development of embedded devices significantly easier. It has built-in sensors, lights, infrared transmitter, GPIO, and can even control other Bluetooth LE devices.

This is version 2.1 of the popular Puck.js - with added accelerometer, gyro, FET, calibrated temperature sensor and improved Bluetooth signal strength!

See a list of tutorials for Puck.js on the main Espruino Website or have a look on the Espruino forum.

Puck.js silicone front cases can also be laser etched with your logo or design for a setup fee of £50 and per-case cost of £3. Please get in touch for more information.

Note: The only difference between Puck.js v2 and v2.1 is the change of magnetometer from ST LIS3MDLTR to Memsic MMC5603NJ. All existing code will work unmodified as long as it isn't using Puck.magRd/magWr for register-level access to the magnetometer.
