CH375B USB Disk Read-write Module USB Flash Disk for Arduino

The CH375B USB Disk Read-write Module is designed for USB disk read-write operations with Arduino. It features a USB interface, which is a common feature in many electronic products, especially microcontrollers. The module uses the CH375 chip, which supports USB host and USB device/slave modes.

In USB device mode, the CH375 is fully compatible with the CH372 and contains all its features. The module supports USB full-speed devices in USB host mode, allowing external microcontrollers to communicate with USB devices according to the USB protocol. The CH375 firmware includes dedicated protocol processing for mass storage devices, enabling the external microcontroller to directly read and write sectors of USB storage devices like USB hard disks, USB flash drives, and U disks.
