Specificatii
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
4.3v3/5V optional
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!
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.
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.
