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.

TTL level interface : can be directly connected microcontroller or other embedded devices, such as 51, STC, AVR, ARM, FPGA , etc., without conversion.

RS232 level interface : connect a computer or Rs232 level serial devices.

RS485 level interface : automatic send and receive control without transceiver control line , the default receiving state , to send status line when sending data .

Freedom Huzhuan four levels : a unique circuit design , USB, TTL, RS232, RS485 freedom of conversion, switched by the switch to achieve physical , convenient and reliable , without interference.

High-speed communications : baud rate up to 2Mbps.

DTR, RTS signals: serial module leads the DTR, RTS signal is versatile, supporting MSP430 microcontroller BSL downloads.

SMT machines , industrial-grade chips : This module uses the whole machine placement process technology, quality and cheap manual patch welding have a qualitative difference , stable and reliable performance guarantee.
