tinypilot computer


This is a compute autopilot computer for pypilot.

  • raspberry pi zero W (wifi enabled) -- the pi zeros are back in production now!
  • mpu9255 (tested to eliminate bad parts)
  • IR sensor + remote for remote control. Can configure most IR remotes from browser.
  • 433mhz RF receiver. Supported wireless remote control included! for additional remotes recommended:8 button remote
  • jlx12864 (daylight visible) display
  • microsd card pre-loaded with tinypilot image
  • enclosure 85x58x33mm (3.35"x2.28"x1.23")

tinypilot is my own custom linux distribution designed specifically for pypilot. This distribution is based off of tinycore linux, and runs completely out of ram after booting offering superior stability.

I measured current draw of 0.07 A at 12 volts with wifi enabled on pi zero W.

An access point "pypilot" is automatically created. It can be configured from a browser and opencpn pypilot plugin.

pypilot is compatible with opencpn (I am a major contributor to OpenCPN)


  • Compass mode - maintain compass bearing
  • GPS - maintain course over ground if connected over (usb, or network)
  • wind (both true and apparent) if wind sensors are provided (usb or network)

A fully functioning autopilot requires 3 parts:

  • autopilot computer (this product)
  • controller
  • rudder drive motor
