Dc electronic load: common questions

What microcontroller does the Dc electronic load use?

The Dc electronic load is built around the STM32-64PIN, from the STM32 family.

How big is the Dc electronic load PCB?

The Dc electronic load measures 106.8 × 73.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dc electronic load?

107 components, from 52 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 Dc electronic load design files?

From the joeferner/dc-electronic-load repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Dc electronic load design in my own project?

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

Can I test firmware for the Dc electronic load without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
