Last Updated or created 2022-04-01

A while back i printed a PCB holder, perfect for accessing contacts on a print, without the need for soldering.

Flashed a doorsensor with Tasmota.

esptool.py --port /dev/ttyUSB0 write_flash -fs 1MB -fm dout 0x0 tasmota.bin

Keep GND and VCC connected, to keep device awake. Else it’s going into sleep mode.

Pull GPio0 to GND @ boottime, to get into flash mode.

3v3 + GND to keep device alive for configuring.

TTL Uart with 3V3
