Adafruit Espruino MDBT42Q Breakout

Experience the JavaScript of things with the Espruino, the world's first open-source JavaScript microcontroller. This compact board comes with an nRF52832 microcontroller pre-installed with Espruino, allowing you to dive into JavaScript programming right away.

The Espruino is equipped with a JavaScript interpreter, enabling immediate interaction with your device. You can set up and send your code without the need for reprogramming the flash, thanks to its fully interpreted nature.

Offering a speedy response time, it simplifies debugging and is ideal for testing projects. A miniature, embeddable sibling of the Pixl.js, it includes a Bluetooth LE module, regulator, and reset button, and can be controlled via any Bluetooth Low Energy device.

Features include the pre-installed Open Source JavaScript interpreter Espruino, enabling instant use even for beginners. With WebBluetooth support for an IDE, programming is straightforward and accessible, right out of the box.

Specifications:- Bluetooth Low Energy- nRF52832 SoC: 64MHz ARM Cortex M4, 64kB RAM, 512kB Flash- 22 x GPIO with various capabilities- 7 analog inputs, 0.1" pin header- Voltage input: 2.5 – 16v, 20uA power draw while advertising- Red and Green LEDs- Built-in thermometer- NFC tag programmable from JavaScript (antenna required)

Note: Some light soldering is needed for power setup. Though it may not be the simplest Espruino to start with, its size is unparalleled for tight spaces. For additional embedded JavaScript solutions, consider the classic Espruino or the compact Espruino Pico.
