High-speed, reliable, stable is capable of leading CP2102 USB to serial module sales in the important reasons. Ultra-small size : the circuit board only 3.1cm X 1.8cm. Ultra- small size , lack of a U disk size , only with a USB port width , even on those two USB ports from a very tight laptop can easily be placed side by side two . 3.3V and +5 V Compatibility: This product perfectly supports 3.3V. Now a lot of high-end microcontroller, such as ARM, STM32, DSP , adopted 3.3V. Additional modules are only compatible 5V level , they do not have 3.3V voltage output function. Power Output: This module can be powered through to the microcontroller system to facilitate debugging. 5V-500mA or 3.3V-100mA. Overcurrent protection : Onboard resettable fuse , even if the positive and negative short-circuit will not damage the circuit board or computer. If there is a short circuit or current exceeds 500mA , the fuse will automatically disconnect , to be short-circuited fuse circuit to restore non- normal . Effectively protect the security of your computer. Transceiver indicator : When the serial line to send or receive data lines , the board will receive indicator lights for easy debugging.
