Raspberry Pi Sensor Connection Card (RPIO-TINY-2)

Connect 3.3V and 5V devices to your Raspberry Pi

Board Design

This board is modeled on the Arduino Sensor Shields, also known as GVS shields. Arduino Sensor Shields bring out the pins of the Arduino to GVS (set of Ground, Voltage and Signal) pins. Unfortunately, the Raspberry Pi can't work with the same 5V GVS sensors and devices as the Arduino since the Raspberry Pi has 3.3V I/O.

The RPIO-TINY-2 card allows the Raspberry Pi to communicate with the same 5V sensors by performing voltage translation from the 3.3V of the Raspberry Pi to 5V.

Features

  • All Raspberry Pi I/O lines
  • 8-bit bidirectional 3.3V to 5V level translator
  • Fuses on 3.3V and 5V power lines

Raspberry Pi I/O lines

All of the Raspberry Pi I/O connections are brought to GVS connectors. This is:

  • (8) GPIO lines on GVS connectors
  • (2) SPI interfaces (can be configured as 5 GPIO lines)
  • (1) UART interface (can be configured as 2 GPIO lines)
  • (1) I2C interface(can be configured as 2 GPIO lines)

Level translators

The board uses an 8-bit wide Texas Instrument TXS0108 voltage translator to convert up to 8 of the 3.3V I/O lines to 5V I/O levels.
