TINKERplate – a Multifunctional I/O HAT for the Raspberry Pi

C1288


TINKERplate is the first Pi-Plate that is fully compatible with the Raspberry Pi HAT standard. With this design, we have borrowed features from our other products and squeezed them down onto this tiny form factor. And like all Pi-Plates, you can increase the number of available I/O ports by stacking up to eight TINKERplates. Some of the features on this HAT include:

  • Four 12-bit 12V analog input channels
  • Two SPDT relays with 3 amp current handling
  • Eight Digital I/O ports with onboard firmware support for
    • Eight Servomotors
    • Eight digital thermometers (DS18B20)
    • Eight strings of Neopixels®
    • Eight pushbuttons
    • Six dimmable LED drivers
    • Six Pulse Width modulators
    • Four ultrasonic distance sensors
    • Eight channels of basic digital I/O
  • Under and over voltage protection on all inputs
  • Compatible with Raspberry Pi 4 model B, 3 model B+, 3 model A+, and 3 model B.
  • All mechanical fasteners included
