Product Description:
The USB to TTL downloader, can be used as serial communication, MCU downloader, STM32 downloader, routing download, etc. The downloader has a USB interface, which can easily extend the download line, while leaving the row of pins interface for short distance download plugging.
STC microcontroller download mode.
1. Wiring as follows: (only 3 wires need to be connected)
USB downloader TXD terminal -> connect the microcontroller P3.0 (RX)
USB downloader RXD end -> connect MCU P3.1 (TX)
USB downloader's GND terminal -> connect microcontroller GND
2. development board or small system using a separate power supply, after connecting the line, at this time will find that even if the development board switch off, the development board power indicator will be lit (faint), is a normal phenomenon, or in accordance with the serial download STC series microcontroller download method (power needs to cold start once).

STM32 microcontroller download mode:
1. wiring as follows: (only 3 wires need to be connected)
TXD side of the USB downloader -> connect the microcontroller PA10 (RX1)
USB downloader RXD end -> connect MCU PA9 (TX1)
USB downloader's GND terminal -> connect microcontroller GND
2. Use a separate power supply for the development board or small system. Or use USB downloader to provide 5V power supply, in the download is required to connect boot0 to VCC out, after the download is complete, connect back to GND and press the reset button to complete the operation.
