Nordic-Switch

This project aims to build a tiny, cord-mounted dimmer with BLE5 capabilities. Board incorporates NRF52832 bluetooth low energy microcontroller with transformless power supply, zero cross detection circuit and triac. The size of the board is only 24*53mm

Build instructions

I ordered a bunch of this boards from JLCPCB. I think it will be unnecessary hard to manufacture them manually at home. Right now I am waiting for them.

Software

I'm searching for a suitable ready to use software. NRF52832 is a really nice chip, the datasheet is pretty clear and peripheral modules are incredibly easy to use. The main problem currently is BLE stack.
