USB Host Module For Arduino (CH375B)

Function Description:

1. CH375B is a universal interface chip of USB bus. It has 8-bit data bus and read, write, chip select control lines and interrupt output. It can be easily hooked up to the system bus of microcontroller/DSP/MCU/MPU and other controllers. . In the USB host mode, the CH375B also provides serial communication, which is connected to the MCU/DSP/MCU/MPU through serial input, serial output and interrupt output.

2. 2×8 connector, easy to attach to the MCU

3. according to jumper selection, can work in parallel mode or serial mode

4. USB status indicator

5. onboard 3.3V LDO 1117, providing 800mA maximum current

6. 5V power supply is powered by the target board

7. 12MHZ crystal oscillator
