Brief Introduction of CH375B U Disk Reader Module USB Host Interface Module 51 U-writable Disc Module with SD Card Module
Key FeaturesProduct Description: - 1 USB interface, in the current electronic products accounted for a very large share of the microcontroller with USB interface
- communication is the most popular one direction microcontroller applications, the module uses for the master chip CH375, CH375 is a
- USB bus interface chip to support both USB-HOST mode and USB-DEVICE/SLAVE equipment. Locally, CH375 with 8-bit data bus and read,- write, chip select control lines and interrupt output that can be easily attached to the MCU / DSP / MCU / MPU and other
- controllers on the system bus. In USB host mode, CH375 also provides serial communication via serial input, output, and interrupt
- output with single / DSP / MCU / MPU, etc. are connected.
- CH375 USB device mode is fully compatible with CH372, CH375 CH372 contains all the features. CH375 USB host mode support USB full-speed device used, the external microcontroller can CH375 accordance with the corresponding USB protocol and USB devices. CH375 also built to handle mass storage device Mass-Storage dedicated communication protocol firmware, the external microcontroller can be directly read and write to the sector as the basic unit commonly used USB storage device (including USB drives / USB flash disk / U disk).
- 2 2 x8 connector, can be easily mounted with the MCU.
- 3 according to the jumper selection, can be operated in parallel or serial mode.
- 4 USB status indicator.
- 5 onboard 3.3V LDO 1117, the largest provider of 800mA current.
- 6 5 V power from the target board power supply.
