A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
USB 8bit Interface Board
An USB interface board which can be used to connect 8 data lines to the USB. The interface comes with a small internal FIFO (384 byte Tx, 128 bytes Rx) and 4 handshake lines which make it suitable for interfacing microcontroller designs to the USB.
The circuit is held as small as possible while still retaining the required features:
* Allows USB-powered and self-powered operation.
* Configuration EEPROM, power LED.
* Connectors for all handshake/control lines (although usually only 4 out of 7 are needed).
* Direct flip-mounting on microcontroller board.
