About the Dimmer esp v1 main PCB

Dimmer esp v1 main is an open source ESP32 PCB design by dagroe, published on GitHub under the MIT license. It is a 4-layer board measuring 44 × 48.1 mm, with 53 components from 30 distinct parts.

Its main chip is the ESP32-C6-MINI-1-N4, from the ESP32 family. Other key parts include the PEC11S-929K-S0015, SGM2212-3.3XKC3G/TR, TYPE-C 16PLT-H10.0 and SN74LV1T125DBVR. By type, the board carries 20 resistors, 12 capacitors, 6 diodes, 5 ICs, 3 connectors and 3 switches.

It belongs with the iot & wireless designs in this gallery.

From the project

a rotary dimmer switch

Also nice to have: be extendable, e.g. easily add multiple dimmer switches or push buttons in multi frames ✅ allow for a second rotary input by rotating the knob while pushing it (e.g. to change color temperature or scenes) — implemented: push + rotate changes color temperature ✅ feature an integrated 230V (or 110V) mechanical switch to switch power of the connected lamp socket (e.g. for emergencies or to reset the lamp when replacing classic wall switches) — implemented: on-board relay + dedicated button be affordable
