16 Lines of 5V I/O on a Raspberry Pi daughtercard

land-boards

I've got a Kickstarter up for a Raspberry Pi daughtercard which connects up to 16 I/O lines of 5V signals.

 

Features List

 

  • Daughtercard to the Raspberry Pi (you supply the Raspberry Pi)
  • 3.3V to 5V bidirectional voltage translators on 16 GPIO (General Purpose Input/Output) lines as follows-
    • (7) 5V GPIO lines on GVS connectors
    • (2) 5V SPI interfaces (can be used as 5 GPIO lines)
    • (1) 5V UART (serial port) interface (can be used as 2 GPIO lines)
    • (1) 5V I2C interface (can be used as 2 GPIO lines)
  • GPIO_4 enables/disables the voltage translators
  • Resettable Fuse protection on the 5V power line - 500 mA limit
  • 49x49mm card form factor with notch to clear the audio jack
