MightyHat is a RaspberryPi Hat add-on board featuring:

  • ATMega328P based microcontroller allows power management (shutdown/reboot) from the push of a button
  • Can easily be used to turn your Pi into an IoT Gateway for sub-ghz networks powered by compatible transceivers (all RFM69 and LoRa)
  • This board is footprint compatible with RFM69W/HW and RFM95/96 transceivers
  • optional LCD for status and messaging
  • 2 general purpose user buttons
  • LithiumPolymer backup UPS (uninterruptible power supply) functionality for the Pi
  • Battery is kept charged while USB power is present

Kit includes the following components:

  • MightyHat main board (no headers soldered)
  • Pi mating long headers (2x20) - these allow your Pi's GPIO to be reused ontop of the MightyHat or can be trimmed off if desired
  • Power control red/green tactile button - this can produce red/green and orange (combine R+G)
  • Reset tactile button (resets Atmega328p)
  • Slide switch (introduced in R2).
  • Two long actuator tactile buttons (introduced in R2)
  • mounting hardware kit (mounts the PiHat ontop your Pi through 4 main mounting holes):
    • 4*17mm standoffs
    • 8*M2.5 screws
  • 1x6 right angled FTDI header - allows programming the Hat when your Pi is turned off

Optional add-ons:

  • Nokia 5110 84x48 monochrome LCD
  • Male or female right angle extension header that brings out all the Pi GPIO to a convenient side access position
  • 2.1mm power jack (power your Pi through this jack instead of uUSB)
  • SMA connector (datasheet) you can solder on the side of the PCB (you will need to ensure your antenna has a mating male SMA connector):
  • Piezo buzzer
  • Your choice of RFM69 or LoRa transceiver (will be soldered and tested with the board when you include it). The transceiver option also comes with a basic monopole wire antenna.
  • Laser cut acrylic case (on special request only)

Not included:

  • RaspberryPi
  • Lithium Polymer Battery (only required if you need backup power)
