1.Upgrade the firmware by SD card. It is easy and convenient to operate.This display board has higher compatibility. Users can select two work modes,they are UART serial port screen mode and 12864 screen mode..
2.Serial port screen mode supports two printing modes: SD card and U disk..
3.Reserve WIFI port, and WIFI function is realized by external WIFI module.
4.Reserve the extension port of filament breaking detection (FIL-DET).
Reserve the extension port of automatic shutdown after printing (PS-ON).
5.2 sets of UART serial port extension ports are reserved for DIY use..

Serial Basic Breakout Board CH340G serial signal serial ic breakout development board usb micro b connector save space diy electronics projects micro b cable jumper wires.
Base on USB converter IC CH340G, there is a wide range of operating systems . You may need to install drivers the first time you connect the chip to your computer's USB port or when there are operating system updates..
The output voltage is 3.3v by default, there is a 3.3v signal, it can also be changed to 5V, changing to 5V will cause the board to output 5V and 5V signals on the VCC pin(3 .3v to 5V by a short circuit selection).
There are two LEDs on the board connected to TX (green) and RX (yellow) for faster viewing of serial traffic.
Suitable for: Arduino Pro Mini, our GPS module, cellular module and many other devices that use serial communication.

With a USB interface, you can directly use the phone data cable on the computer point of view positioning effect.
