Here ESP-01 is programmed using a CP2102 USB-TTL converter; it can also be programmed using an Arduino UNO board. Here in my case, I have used a CP2102 module and the steps for doing this are ...

It has GPIO, SPI, I2C, ADC, PWM AND UART pins. It can be programmed with Arduino IDE. On board NodeMCU has CP2102 IC which provides USB to TTL functionality. To learn more about ESP8266, check other ...

To that end, a USB port is also provided, hooked up to the uC with the cheap CP2102 USB bridge chip as per most Arduino-like designs. The thing that makes this build a little unusual is the ...
