Driver: Click here to open (Windows/Mac_OS/Linux)

Features:

Fully compatible with Windows, Mac OS, Linux, support for both X86 and X64

Size: 52.5mm x 17.6mm

Functions:

Automatic recovery fuse: intelligent anti-burn, equipped with 500mA automatic recovery insurance, automatic disconnection of current over 500mA, protect your device and USB port, even if it is short circuit will not affect, after the circuit is normal, you can restore the link.

CP2102 chip: USB interface chip CP2102, high stability and high performance, communication speed up to 2Mbps.

The TTL level is compatible with the 3V3 level standard. It comes with 5V and 3.3V, 4.2V power output ports, which can supply power to the MCU system. The DTR/RTS output interface can be reserved, and the level of the two pins can be overridden through the serial port. When some MCUs download the program, the reset can be completed automatically.

Two-color LED indicator: The indicator light is red and blue respectively to indicate the working status of the module. The TX and RX lamps will flash when there is data transmission, and the transmission status is clearly visible.

3V3/4V2 output selection switch: defaults to output 3.3V from V0 port, short circuit 3V3/4V2, output 4.2V from V0 port, 5V interface directly output 5V.

Package includes:
