Open power profiler
About the Open power profiler PCB
Open power profiler is an open source RP2040/RP2350 PCB design by Guiimartinho, published on GitHub under the MIT license. It is a 4-layer board measuring 150 × 100 mm, with 365 components from 149 distinct parts.
Its main chip is the SC1632, from the RP2040/RP2350 family. Other key parts include the TPD4E1U06DBVR, TPS259621DDAR, TPS2116DRLR, TPS3808G01DBVR and LP5907MFX-3.3/NOPB. By type, the board carries 163 resistors, 112 capacitors, 39 ICs, 24 diodes, 16 transistors and 5 connectors.
It belongs with the test & measurement and dev boards & breakouts designs in this gallery.
From the project
Open-source PPK2-class power profiler built on the Raspberry Pi Pico 2: 100 kSPS, 100 nA to 1 A auto-ranging, source meter and ampere meter modes, USB stream.
The carrier board of the instrument: schematic, PCB layout and fabrication outputs. The simulations of its circuits are a package of their own, in ../simulation/.
The instrument is two boards. A Raspberry Pi Pico 2, bought ready-made, is the controller. It plugs into two rows of pin sockets on the carrier board designed here, which holds everything else: power input, source meter, shunt ladder, signal chain, side data and connectors. Sections 4.11 and 5 of the specification define the interface.

The Open power profiler is built around the SC1632, from the RP2040/RP2350 family.
How big is the Open power profiler PCB?
The Open power profiler measures 150 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Open power profiler?
365 components, from 149 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Open power profiler design files?
From the Guiimartinho/open-power-profiler repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Open power profiler design in my own project?
Yes, under the terms of its MIT license, which Guiimartinho chose for the repository.
Can I test firmware for the Open power profiler without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
