intro

If you want to hook up your raspberry pi to interface with the rest of the world, this is the right place to look!

rpi_serial

The rpi_serial board is the simplest breakout board for the Raspberry pi.

It breaks out the following serial buses:

• SPI0
• SPI1
• I2C
• UART

As the rasberrypi runs at 3.3V IO signal levels, the board allows 5V peripherals to be connected. The board can be configured for 5V operation or for 3.3V operation but not both.

expansion boards

• • SPI_LCD
  • SPI_6FETs
  • SPI_Servo
  • SPI_LM35
  • SPI_DIO
  • SPI_relay

Planned are the optocoupler expansion board and the button expansion board. If you have suggestions for more, please let us know.
