I2C-Repeater with switch for Raspberry PI finished

Description:

The GPIO interface of the Raspberry PI is designed for 3.3V level. The I2C repeater raises the level of the SCL and SDA pins so that they are recognized clean 5V I2C slaves to 5V.

The following improvements we have implemented:

• Double-sided PCB.
• It is now possible to equip the I2C terminal above.
  Thereby it will also fit the Raspberry PI with heatsinks.
• About a solder bridge the supply voltage of the Raspberry PI for external I2C modules can be used if you wish to use no extra power supply.
• Switch Button on GPIO4.
  Functions can be programmed to the button, such as Shutdown of the Raspberry PI
• LED on GPIO27
  Functions can be programmed on the LED.

Size of the circuit board 36 mm x 22 mm
