Electronicload: common questions

What microcontroller does the Electronicload use?

The Electronicload is built around the STM32F303K_6-8_TX, from the STM32 family.

How big is the Electronicload PCB?

The Electronicload measures 54.5 × 80 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Electronicload?

62 components, from 33 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 Electronicload design files?

From the GM4AJK/electronicload 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 Electronicload design in my own project?

The repository has no license, so all rights stay with GM4AJK. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Electronicload 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.
