Nabeel's Joulemeter: common questions

What microcontroller does the Nabeel's Joulemeter use?

The Nabeel's Joulemeter is built around the RP2040, from the RP2040/RP2350 family.

How big is the Nabeel's Joulemeter PCB?

The Nabeel's Joulemeter measures 80 × 79.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nabeel's Joulemeter?

38 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nabeel's Joulemeter design files?

From the UCLA-Bruin-Supermileage/SMV_boards_2024-2025 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Nabeel's Joulemeter design in my own project?

The repository has no license, so all rights stay with UCLA-Bruin-Supermileage. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Nabeel's Joulemeter 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.
