Adafruit Espruino MDBT42Q Breakout
Adafruit Espruino MDBT42Q Breakout is a Bluetooth-enabled, open-source, JavaScript-based module, mounted on a easily soldered board. The MDBT42Q Breakout features a Nordic Semiconductor nRF52 Series SoC (System on Chip), pre-programmed with Espruino, an open-source JavaScript interpreter for multiplatform microcontroller development. The integrated Espruino Module includes Bluetooth Low Energy (BLE), 64k of RAM, and 512k of Flash in a compact, low-power package. The MDBT42Q Breakout Board's 0.1" pin header offers 22 GPIO (capable of PWM, SPI, I2C, UART), with 7 analog inputs.
