About the Power Monitor V2.1 PCB

Power Monitor V2.1 is an open source ESP32 PCB design by Filips-Talums, published on GitHub. It is a 2-layer board measuring 33.7 × 113.8 mm, with 21 components from 15 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the INA226 and DM-OLED096-636. By type, the board carries 5 ICs, 3 capacitors, 3 resistors, 1 buzzer, 1 fuse and 1 diode.

From the project

ESP32-based DC inline power monitor for measuring voltage, current, and power between a DC power source and external load.

This directory preserves the project's KiCad design history and manufacturing files:

- PowerMonitorV1/ contains the first PCB design. - PowerMonitorV2/ contains the version 2 project, its libraries, 3D model, and tracked recovery material. - The top-level PowerMonitorV2.1.kicad files contain the later version 2.1 board project files. - PCBV2PRINTING/ and PCBV2PRINTING.zip contain version 2 manufacturing outputs.

Power Monitor V2.1: common questions

What microcontroller does the Power Monitor V2.1 use?

The Power Monitor V2.1 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Power Monitor V2.1 PCB?

The Power Monitor V2.1 measures 33.7 × 113.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Power Monitor V2.1?

21 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Power Monitor V2.1 design files?

From the Filips-Talums/DC-Inline-Power-Monitor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Power Monitor V2.1 design in my own project?

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

Can I test firmware for the Power Monitor V2.1 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.
