6.The USB head is a male head, and 3.3V can be directly connected to the STC system USB port.
7.This downloader supports online programming of all series of STC single-chip microcomputers. It has USB to TTL and USB to serial port functions and can be used for the upgrade of USB to TTL electronic products without affecting normal serial port communication tests! It supports high wave rate 115200 and is also suitable for programming STC12 series, STC11 series, and STC15 series!
Pin Description:
- G: Ground wire (GND) connected to the GND of the STC single-chip microcomputer.
- Q: Power supply (OUT VCC) connected to the VCC of the STC single-chip microcomputer.
- R: Receive (RXD) connected to P3.1 of the STC single-chip microcomputer.
- T: Transmit (TXD) connected to P3.0 of the STC single-chip microcomputer.
Parameters:
1、System Compatibility: Fully supports drivers for Win8/Win7/WinXP/Win2k/WinCE/Linux/Mac systems, both 32-bit and 64-bit.
2、3.3V and 5V Compatibility: This product supports 3.3V voltage.
