Smart regulator: common questions

What microcontroller does the Smart regulator use?

The Smart regulator is built around the ESP-WROOM-32, from the ESP32 family.

How big is the Smart regulator PCB?

The Smart regulator measures 82.5 × 48.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smart regulator?

35 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Smart regulator design files?

From the physiii/smart-regulator repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Smart regulator design in my own project?

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

Can I test firmware for the Smart regulator 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.
