Warning: Construction zone.
Below is correct, but IO0 is directly connected to VCC, so we cannot bring ESP-12 into flash mode. Will check for some OTA mode that can be used.
With just two additional wires we can use Tasmota with the SP108E.
The trick is to hold the STM32F0 controller in reset. Then we do not need to cut any traces on the PCB because all pins of the STM32F0 are inputs.
Another warning: I did not yet proof it actually works, this is work in progress.
- Wire 1 - NRST (pin 7) of STM32F0 to GND
- Wire 2 - IO4 of ESP-12 to R4
