ModularPowerSupply: common questions

What microcontroller does the ModularPowerSupply use?

The ModularPowerSupply is built around the ESP32-DEVKITC-32D, from the ESP32 family.

How big is the ModularPowerSupply PCB?

The ModularPowerSupply measures 9 × 25 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ModularPowerSupply?

35 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the ModularPowerSupply design files?

From the Animal-Crate/Animal-Crate repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ModularPowerSupply design in my own project?

Yes, under the terms of its AGPL-3.0 license, which Animal-Crate chose for the repository.

Can I test firmware for the ModularPowerSupply without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
