The CH375B USB Disk Read-Write Module enables Arduino and other microcontrollers to easily communicate with USB flash drives and other USB mass storage devices. Featuring jumper-selectable parallel and serial operation modes, it offers flexibility in interfacing with a wide range of systems. The onboard 3.3V LDO regulator (1117) delivers up to 800mA current, while the built-in firmware handles USB mass-storage protocols, allowing sector-level read and write operations. Equipped with a 12MHz crystal and a convenient 2×8 connector, the CH375B module simplifies integration into projects requiring USB data storage and retrieval. Compact, reliable, and versatile, it is ideal for data logging, embedded systems, and Arduino-based applications. Featured By RoboticsBD.
