Multiple Interface

I designed this board to be able to quickly setup a project without using C>100 cables on the table. The board includes the following hardware :

• RS485 interface (with 120 ohm resistor)

• Buzzer

• Dataflash SPI (Atmel) or dataflash I2C (Xicor) up to 512 Mbytes

• LED IR

• IR receiver

• Clock IC (X1227) with eeprom I2C

• LM335 for temp. mesure or Dallas 18x20

• 3 push button

• Display daughter board for LCD or EA-DOG display or 4*7 segments displays 

• Linear regulator if you want to power the board (3,3V or 5V) with VIN (jumper)

• Access via connectors to I2C bus, to serial TTL bus 

The schematic files are available (under free Kicad software) and PCB too (with small errors!)
