This USB-to-TTL downloader can be used as serial communication, single-chip downloader, STM32 downloader, routing download, etc. This downloader has a USB interface, which can facilitate the extension of 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 to 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 the smallest 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 MCU method download (the 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 to the single-chip PA10 (RX1)
The RXD end of the USB downloader -> connect to the single-chip PA9 (TX1)
GND terminal of USB downloader－>connect MCU GND
2) 　The development board or the smallest 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.
