Try the JavaScript of things with the Espruino – the world’s first open-source JavaScript microcontroller! This little board has an nRF52832 microcontroller pre-programmed with Espruino all ready to go so you can start playing with Javascript-microcontrollers. Warning: if you only use Assembly and think that even embedded C/C++ is for wimps, this device might explody your head.
The Espruino is a tiny computer with a JavaScript interpreter, allowing for instant feedback from whatever device you’re working with. Simply set up your code with the Espruino and send it to the device without having to wait for the board to erase and reprogram the flash – it’s fully interpretted!
The Espruino’s fast response time has a lot of advantages. It allows for quick and easy debugging and is a great way to test your project before your big reveal. This module is a miniature, embeddable version of the Pixl.js – it just contains the Espruino-running Bluetooth LE module, regulator and reset button. In addition, you can control the Espruino from almost anything that has Bluetooth Low Energy.
22 x GPIO (capable of PWM, SPI, I2C, UART), including 7 analog inputs – 0.1″ pin header
2.5 – 16v voltage input, 20uA power draw when advertising
Red and Green LEDs
Button
Built in thermometer
NFC tag programmable from JavaScript (when an antenna is connected)
Some light soldering is required to power this small breakout. It isn’t the easiest Espruino to start with, but when you need to go small, this one is as tiny as it gets.

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.
