Puck.js is entirely autonomous. Press a button and it'll control other Bluetooth or Infrared devices within range, without the need for a phone app or hub
Button, Magnetometer, Accelerometer, Gyro, IR & RGB LEDs, Temperature and light sensor, FET output and a programmable NFC tag - Puck.js has everything you need out of the box!
9 IO pins are available (7 of which are on a 0.1" pitch), with PWM, analog, I2C, SPI and Serial so you can easily add your own hardware!
Puck.js isn't just beacon. It can be a Bluetooth LE HID device too - a keyboard or multimedia control. It can then create keypresses in response to external stimulii, which could be a button press, a door opening, even another Bluetooth device coming within range!
But it gets better! Puck.js can connect to other BLE devices in 'central' mode as if it were a phone, and can even receive other devices' advertisements!
With a common API between devices, you can move your project over to other Espruino platforms (like WiFi) with minimal effort!
With Web Bluetooth you can start programming straight out of the box - no wires or software required!
Puck.js's is Open Source (software and hardware), so it's easy for you to tweak its functionality or see how it works.
Puck.js can measure light, temperature, movement, magnetic fields and capacitance, can control Infrared devices, and has a clever tactile switch that turns the Puck into one big button.
And it does all this with a year-long battery life on a common CR2032 battery that costs $0.20!
Puck.js comes with a smooth silicone cover - either white, black tint, red, yellow, green or blue.
Do you want something special? No problem! We can provide unbranded cases, can laser etch your logo on to the silicone top, and for larger orders can even provide the case in custom colors.
