About the 2x2RemotePanel PCB

2x2RemotePanel is an open source ESP32 PCB design by kharper55, published on GitHub. It is a 4-layer board measuring 190 × 162.2 mm, with 209 components from 29 distinct parts.

Its main chip is the ESP32-WROOM-32D, from the ESP32 family. Other key parts include the OPA837IDBVT, TPS7A9201DSKR, 74LVC14APW,118 and CP2102N-Axx-xQFN28. By type, the board carries 46 resistors, 37 capacitors, 11 diodes, 8 transistors and 7 ICs.

From the project

All CAD pdfs and RAW files from KiCAD6 and some nice pin mapping references + block diagrams. Custom symbol and footprint library (not provided) needed to rebuild Gerbers (provided as-is).

Contains schematic, PCB, BOM (entire KiCAD project + PDF prints) and Gerber files for 3x 4 layer mixed signal PCBs. KiCAD project has since seen edits in silkscreen and rectifying some issues with DNP parts.

The KiCad project lives in the kharper55/soundSteering_CAD_FINAL repository on GitHub; these links point at the commit this page was built from.

2x2RemotePanel: common questions

What microcontroller does the 2x2RemotePanel use?

The 2x2RemotePanel is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the 2x2RemotePanel PCB?

The 2x2RemotePanel measures 190 × 162.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the 2x2RemotePanel?

209 components, from 29 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 2x2RemotePanel design files?

From the kharper55/soundSteering_CAD_FINAL repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the 2x2RemotePanel design in my own project?

The repository has no license, so all rights stay with kharper55. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 2x2RemotePanel 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.
