Brief introduction
The STC Universal Programmer is the only programmer that can work for all STC micro-controllers. The programmer has both RS-232 port and USB port. USB is also used as power supply port. Programmer can be configured to work in either RS-232 mode or USB mode port through jumper.
The programmer works for both normal voltage (5V) and low voltage (3.3V) devices. The working voltage can be configured through a switch.
There are two external ports on the programmer. They could be used to program Non-DIP devices or STC microcontroller devices on other boards.
