This USB to TTL downloader can be used as serial communication, single-chip downloader, STM32 downloader, route downloading, etc. This downloader has a USB interface, which can be convenient to extend the download line, and reserve a pin interface for short-distance downloading.
 
STC MCU download mode:
 
1) The wiring is as follows: (only need to connect 3 wires)
 
The TXD end of the USB downloader -> connect the MCU P3.0 (RX)
 
The RXD end of the USB downloader -> connect to the microcontroller P3.1 (TX)
 
GND terminal of USB downloader－>Connect MCU GND
 
2) The development board or small system uses a separate power supply. After connecting the cable, you will find that even if the development board switch is turned off, the development board power indicator will light up (weak). This is a normal phenomenon. Download STC according to the serial port. Serial single-chip method download (power supply needs to be cold-started once).
 
STM32 MCU download mode:
 
1) The wiring is as follows: (only need to connect 3 wires)
 
The TXD end of the USB downloader -> connect the single-chip PA10 (RX1)
 
The RXD end of the USB downloader -> connect the single-chip PA9 (TX1)
 
GND terminal of USB downloader－>Connect MCU GND
 
2) 　The development board or small system uses a separate power supply. Or use a USB downloader to provide 5V power supply. When downloading, you need to connect boot0 to VCC. After the download is complete, connect it to GND and press the reset button to complete the operation.
