PL2303HX module Download line on STC microcontroller USB to TTL Programming unit In the nine upgrade

Product Features: 

1. Uses imported brand new PL2303HX control chip for high-speed and stable flashing 2. Equipped with a 500mA self-resetting fuse for overcurrent protection 3. Two data transmission indicator lights are set to monitor data transmission status in real time 4. Reserved 3.3V and 5V pin interfaces for flashing systems requiring different voltage power 5. Interface pins are parallel to the board instead of perpendicular, making it easier to connect Dupont wires during flashing 6. The entire circuit board is covered with high-quality transparent heat-shrink tubing, insulating the PCB from the external environment to protect the board from accidental metal short circuits; the transparent material does not affect the visibility of the silk screen or the monitoring effect of indicator lights 7. Finished product packaging is in anti-static bags to ensure the board's quality is not compromised before use 8. Supports XP, WIN7, and other systems
