Features:

Independent development Laser Sensor Module for USB-TTL/STC-ISP programmer on line USB  interface，for laptop users
1. Support USB1.1 or USB2.0 communication;
2. Fully support WIN98,WINME,WIN2000,WINXP,VISTA,WIN7 etc.operating system;
3. USES USB port power supply, ，on board with 500mA self recovery fuse or insurance resistance，protect the computer motherboard from accidentally burned;
4. When program the chip ,you can use Target power system power supply ，also can use 
programming unit from USB port 
Take electricity supply target board，but need make sure the target current is not bigger than 500mA，to avoid cannot normal programming;
5.  Programming complete the program is running will not affect the target board;
6. support on STC series chip burn;
7. The programmer to provide 3.3 V and 5 V voltage output interface;；
8.  Faster than parallel programming is more stable, more convenient laptop users use;
9.  Original good chip ,more stable
