CH376S USB module U disk / SD card reader module USB Host module board

Tutorialhttp://arduinobasics.blogspot.my/2015/05/ch376s-usb-readwrite-module.html  USB interface in the current electronic products accounted for a very large share of the microcontroller with USB interface communication direction of one of the most popular microcomputer application master chip module using the CH376S, CH376S is a USB bus interface chip to support USB-The host and USB-DEVICE/SLAVE equipment the way. Locally, CH376S with 8-bit data bus and read, write, chip select control lines and interrupt output can be easily attached to the system bus of the microcontroller/DSP/MCU/MPU controller. USB host mode, CH375 also provides serial communication via serial input, serial output, and interrupt output monolithic/DSP/MCU/MPU connected.     CH375 USB device mode is fully compatible with CH372, CH376S contains all the features of the CH372. Common CH375 USB host mode support USB full-speed device, external microcontroller can through the the CH375 in accordance with the USB protocol and USB device communication. CH375 firmware also built a dedicated protocol processing Mass-Storage mass storage devices, external microcontroller can be directly used as the basic unit of reading and writing in sectors USB storage devices (including USB hard disk/USB flash drive/U disk).     2×8 connector, easy with the MCU mount.     Jumper selectable, can work in parallel or serial mode.     USB status indicator.     Onboard 3.3V LDO 1117, provides 800mA current.     5V power supply is powered from the target board.     12MHZ crystal.
