Programming the Wemos with a FTDI Programmer (see here)
- 1 ----> GND -----> black ---->
- 2 ----> CTS ----->
- 3 ----> 5V/3.3V ---> red
- 4 ----> TXO ----> blue
- 5 ----> RXI ----> white
- 6 ----> DTR
A driver is available here.
- Power the module (3.3 Volts)
- Connect the RESET pin to the GND
- Connect the GPIO-0 pin to the GND
- Disconnect the Reset pin from the GND
- Disconnect the GPIO-0 pin from the GND
- Upload your sketch
