Jolt.js is a programmable Bluetooth motor driver board. Control powerful external devices such as lights, motors, solenoids and relays, all from a device that can run for months or even years on a battery!

This is a bundle containing a Jolt.js plus extra useful components, in a box - you can also buy Jolt.js on its own

This bundle contains:

Jolt.js and its silicone case
A 300mAh Lithium Polymer battery that can plug in and be recharged by Jolt.js when it is connected to USB, providing enough power for 6 months with Bluetooth enabled!
4x Qwiic connectors, allowing connection to the Bangle's 2x FET outputs and 12 GPIOs
A 2mm screwdriver that fits Jolt.js's terminals perfectly
An Instruction card and clear plastic box

You can be up and running in no time - plug in the battery, connect something to the screw terminals and start making things happen in the real world immediately!

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.
