Traces on bottom side from STM to HC245 (actually R3 and R4)

For the hardware mod to make it working without the STM32F0, we need to break one of the traces on the bottom of the PCB. Then connect GPIO4 of ESP-12 with either R3 or R4. Sorry for being vage here, I did not try that yet and will add exact details later.
