Jolt.js is a programmable Bluetooth motor driver board

With the Espruino JavaScript interpreter on its internal ARM microcontroller, software can be uploaded, debugged and modified wirelessly from any modern computer or phone, making development of embedded devices significantly easier. Jolt.js has 8 high power outputs, capable of 1A each, as well as 4 Qwiic connectors. It can even control and be controlled by other Bluetooth LE devices.
