The Espruino Puck.js is a low energy Bluetooth smart button that can be programmed and debugged wirelessly with JavaScript. It is both multi-functional and easy to use, with a custom circuit board, the latest Nordic chip, Bluetooth LE, NFC, magnetometer, temperature sensor, RGB LEDs, infrared and much more, all enclosed in a tiny silicone case. You get all the joy of an interpreted language, with some great sensors and wireless functionality!
Puck.js comes with the Open Source JavaScript interpreter Espruino pre-installed, which makes it incredibly easy to use and means you can get started in just seconds, without any prior programming experience. You can start programming straight out of the box – no wires or software required!
Features:
Espruino JavaScript interpreter pre-installed
nRF52832 SoC – Cortex M4, 64kB RAM, 512kB Flash
8 x 0.1″ GPIO (capable of PWM, SPI, I2C, UART, Analog Input)
9 x SMD GPIO (capable of PWM, SPI, I2C, UART)
ABS plastic rear case with lanyard mount
Silicone cover with tactile button
MAG3110 Magnetometer
IR Transmitter
Built in thermometer, light and battery level sensors
Red, Green and Blue LEDs
NFC tag programmable from JavaScript
Pin capable of capacitive sensing
Includes x1 Lithium Coin Cell 3V Battery
Note: Do not re-fit the PCB upside-down or force it into the case. If positioned correctly it should slide in. Forcing the PCB or fitting it upside-down could damage the aerial which will stop your Puck’s Bluetooth from working correctly.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
