Description

Zigbee2Tasmota PCB. Main modules:

  • Wemos D1 mini (~$2)
  • DL-20 Zigbee (CC2530). Module usually comes from Aliexpress with soldered 90 degree pins - need to solder "regular" pins. (~$8)

PCB designed for 70x45x30 mm box from Aliexpress (~$1)

Added optional place for 433Mhz module (WL101-341 and similar), pads and place in box for PWM modules (LR7843).

Result: Look at image below with Wemos, DL20, WL-101 and PWM (LR7843) placed in box. As fact - 433 module works not perfect (low distance), may be anthena not in best form:). I think I'll replace it with DS18S20 sensor to check temp inside box. PWM used for dimming LED, Zegbee works with 3 modules right now (and 2 ordered).

All firmware update instructions are on Tasmota home page.
