USB to ESP8266 ESP-01 WiFi Adapter Module with CH340G - Serial Converter for Arduino IoT Projects & Wireless Programming

p{margin-block-start: 0; margin-block-end: 0}USB to ESP8266 ESP-01 Wireless Wifi Adapter Module Wi-Fi CH340G driverDescription:USB to ESP-01 adapter module has CH340G USB to TTL driver IC onboard, so you can easily use your computer to do ESP-01 functional debugging. ESP-01 serial wifi module can be directly plugged into the yellow pin header without any connection wires.Features:Working voltage: 4.5V - 5.5V (On-board 3.3v LDO Regulator)Working current: 300mA(LDO regulator can supply)Selectable working mode: On-board toggle switch. UART side for serial TTL debugging by AT commands, PROG for firmware programmingUSB to serial TTL chip: CH340GLogic level: 3.3VApplications: Home automation, sensor networks, industrial wireless controlFAQ:Q:Can this be programmed for a baud rate of 9600?A:The programmer can accept any baudrate however the baudrate you have to use totally depends on the module which is connected, and a a standard ESP01 cannot be programmed at 9600bps.Q: After programming the esp-01 and my arduino uno, can i program over the air (ota)A: Yes, you can do that. That is a base function of the ESPQ: After successful upload of program I get a msg about hard RESET. After a few minutes I unplug USB programmer and switch position to UART. The ESP01 module does not startup with program uploaded no response. I unplug and return to program mode and upload successfully a different program, but OLD program is still present. This USB programmer does not reset the module or erase old program. what am I doing wrong?A: This module does not reset automatically, it is preferable to unplug and replug after each operation. So after programming, you need unplug, switch to UART, replug. When you want to program, you need unplug, switch to PROG, replugQ: What is the LDO regulator and its maximum current?A: The LDO regulator is AMS1117-3.3V, maximum current is 1A
