This module serves as the program download and debugging motherboard for the ESP-01/01S ESP8266 serial WIFI module, eliminating the hassle of wiring. Simply plug ESP-01/01S into the motherboard and connect the USBType-C cable. The bottom plate leads out all the pins of the ESP-0 1/01 s module, as well as external wires. It can also be used as a regular USB to 3.3V TTL serial port tool without inserting ESP-01/01s.
Usage:
Before use, install the CH340USB to TTL serial port driver program on the computer, and recognize the COM port in the device management. The motherboard is integrated with an automatic download circuit. Simply click download on the program download software and wait for the program download to complete. The motherboard also introduces the EN reset button and the 100 download mode button, which can be manually downloaded. When downloading a program, simply hold down the button and do not release it, which is equivalent to pulling down the 100 pin. Then press the EN reset button on the motherboard again to enter the download mode. Click the download option on the download software, wait for the program to download, and finally release the 100 button. Press the reset button, and the downloaded program can run.
