The USB to TTL downloader can be used as a serial communication, a single-chip downloader, an STM32 downloader, a route download, etc. The downloader has a USB interface, which can easily extend the download line, and at the same time reserve a pin header interface to facilitate short-distance download and connection.
Features
1. Not only the power lamp PWR, but also the TXD and RXD indicators, so that you can intuitively understand whether the product is working without the instrument;
2. Support WINDOWS 98/ME/2000/XP/Server 2003/VISTA/Server 2008/Win7/Win8 32 bit/64 bit/win10 64 bit
3. Small volume performance

5. Micro-USB interface data cable
6. With 3.3V regulator chip, ultra stable operation, compatible with 5v, 3.3V microcontroller program download and debug!
7. Module size 15.7mm*15.7mm, PCB size 16.02mm*17.4625mm
STC Microcontroller Download Mode
1) Wiring as follows:(only need to connect 3 wires)
TXD terminal of USB downloader -> connect single chip microcomputer P3.0 (RX)
RXD end of USB downloader -> connect single chip microcomputer P3.1 (TX)
GND end of USB downloader -> connect single chip GND
2) The development board or small system uses a separate power supply. After connecting the cable, it will be found that even if the development board switch is turned off, the power indicator of the development board will be lit (weak). This is a normal phenomenon, or download the STC according to the serial port. Series MCU method download (power supply needs to be cold start once).
STM32 Microcontroller Download Mode
1) Wiring is as follows:(only need to connect 3 wires)
TXD terminal of USB downloader -> connect single chip microcomputer PA10 (RX1)
RXD end of USB downloader -> connect single chip microcomputer PA9 (TX1)
GND end of USB downloader -> connect single chip GND
2) The development board or small system is powered by a separate power source. Or use the USB downloader to provide 5V power supply. In the download, you need to connect boot0 to VCC. After the download is complete, connect it back to GND and press the reset button to complete the operation.
Support win7 32-bit, 64-bit operating system, support win xp operating system
