What is it?

The PPPM performs Voltage, Current and Power measurements in low voltage systems. With a max. input voltage of 26V and a max. current of 3.6A it is suitable for any 12V powered device.

You can use it in your caravan, camper, boat, yacht, lab and just about anywhere you want to monitor the voltage of your system and the current drawn by the devices.

With a bit of programming in micropython and soldering you can easily improve the functionalities and the max. current.

In the current configuration it is equipped with a 0.1Ohms shunt. The measurements are performed on the high side!

Why did you make it?

I needed a device to easily measure the power output of a power supply. Normally, I needed to take two measurements with my one multimeter.

What makes it special?

The small form factor of 30x76mm
Instant values on the OLED display
3 "pages" with big values
1 summary "page"
User button
2 user LED
2 headers for external acess to the pins (not all pins are acessable)
Robust terminal block for up to 2.5mm²
Button and LEDs user configurable (requires programming)
Completely open source

The device comes with ready to use firmware. The button switches through the pages. The green LED blinks.
