2Pcs CH340C USB Type-C to UART Serial Port Adapter Downloader STC Microcontroller Program UART Serial Port Module Automatic Download Burner Module without Cold Start
For STC series microcontrollers, if you want to download ISP, you must receive
the serial command from STC-ISP software during power on reset before starting
to execute the ISP program, that is, cold start download. If using a regular
USB to TTL serial port downloader, it is necessary to manually power off and
then on the STC microcontroller. Frequent manual operation may not be
convenient enough. Therefore, using this module can eliminate the trouble of
frequent manual power-off and power-off of STC, and automatically download the
program for power-off and power-off. When not used for downloading STC
programs, it can be used as a regular serial port module. Introduce RTS and
DTR flow control pins, the module is compatible with 5V/3.3VTTL level
communication. Module size: 38.6mm  25.3mm
