About the PowerSupply PCB

PowerSupply is an open source ESP32 PCB design by Dennis960, published on GitHub. It is a 2-layer board measuring 37.6 × 37.6 mm, with 19 components from 13 distinct parts.

Its main chip is the ESP32-C6-MINI-1-N4, from the ESP32 family. Other key parts include the C720477, BidirectionalLogicLevelShifter, LinearVoltageRegulator and USB-TypeC. By type, the board carries 7 ICs, 7 capacitors, 4 resistors and 1 connector.

From the project

SmartCube is a smart cube that can magnetically connect to other cubes in four directions

This folder contains the KiCad projects for the SmartCube LED module, power supply module, and pogo pin connectors. It also includes helper scripts for panelization of the PCBs for manufacturing.

The KiCad projects all use the same shared library located in the libs folder.

If having problems loading footprints or 3d models, make sure to add the symbol and CustomFootprints libraries in KiCad.

PowerSupply: common questions

What microcontroller does the PowerSupply use?

The PowerSupply is built around the ESP32-C6-MINI-1-N4, from the ESP32 family.

How big is the PowerSupply PCB?

The PowerSupply measures 37.6 × 37.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PowerSupply?

19 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the PowerSupply design files?

From the Dennis960/SmartCube repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PowerSupply design in my own project?

The repository has no license, so all rights stay with Dennis960. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PowerSupply 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.
