CH375B USB Flash Disk Read Module for Arduino

CH375B is a USB bus general interface chip with 8-bit data bus and control lines for reading and chip selection and output interruption, which can be easily attached to the system bus of controllers such as MCU / DSP / MPU. In USB host mode, CH375B also provides serial communication, which can be connected to MCU / DSP / MPU, etc. via serial input, serial output, and interrupt output.

Features:

• Can be operated in parallel or serial mode according to the jumper
  
• USB status indicator
  
• Onboard 3.3V LDO 1117, providing current up to 800mA
  
• 5V power supply from the target board
  
• 12MHZ crystal
