What the heck is PIPduino?

Introducing PIPduino
Our Jeep's steering servo controller, with this icky baseboard, was missing something. What?

Power and ground rails and a voltage regulator, that's what. So I made a 'duino clone with features for Putting In Projects and called it PIPduino.
  • Color-coded power and ground rails for each analog and digital pin, 
  • Dedicated I2C bus with 4 ports and pullups,
  • Combo SPI / ISP connector, 
  • Serial/FTDI connector,
  • Onboard voltage regulator, and
  • Flexible power options.
Goodbye shields. Use low cost breakout boards instead.

Before PIPduino (ick). And after (ah, much nicer).
Available soon on Tindie.


  1. I did the same thing for my teensy board:

    1. Nice. Might be fun to clone a Teensy into the PIPduino form factor...

      Also, Micro Python on Teensy? Cool. Ibrahim got Micro Python running on the OpenMV Cam (STM32F407).

    2. Where did you get the nice colored headers?

    3. I get 'em in bulk through Aliexpress.

  2. Nice! Except that I'd leave off the regulator. I like to keep the regulator external, that way I just need one for all the 5V devices. Simplifies things.

    1. But Ted, you *can* use an external regulator, just power the board from the 5V/GND pins. That's what I'm doing with it on the self-driving Jeep.

  3. Excellent method to harness the power of the 328... W/O all that shield crap.
    I've been doing mine on those small Veroboards from Thaishine or Tayda on Fleabay, Tayda is a little more generous but Thaishine is a US branch of Tayda and a little more expensive then Tayda ~ +10% But 3 to 4 day shipping via 1st class mail makes up for it,
