About the Eps-8pin rev3 PCB
Eps-8pin rev3 is an open source ESP32 PCB design by nathanfraske, published on GitHub under the Apache-2.0 license. It is a 4-layer board measuring 96 × 40 mm, with 63 components from 31 distinct parts.
Its main chip is the ESP32-C6-MINI-1-N4, from the ESP32 family. Other key parts include the TJA1051T/3/1J, LP5907MFX-3.3/NOPB, TPS2121RUXR, INA238AIDGSR and INA181A2IDBVR. By type, the board carries 20 capacitors, 14 resistors, 10 ICs, 2 connectors, 2 switches and 2 diodes.
From the project
Single source of truth for the CURRENT Standard-line beta products. The machine-readable equivalent is scripts/cecbetamanifest.py; audits and waves consume that manifest instead of recursively discovering whatever happens to be under beta/.
Single source of truth for the CURRENT Standard-line beta products. The machine-readable equivalent is scripts/cecbetamanifest.py; audits and waves consume that manifest instead of recursively discovering whatever happens to be under beta/.
Rule: for any beta-line change, edit only a manifest-declared directory below. Historical captures live under old-revisions/ and are never project discovery inputs. eps-8pin-rev3 is the one EPS product; rev3 identifies its current design revision, not a product variant.

Eps-8pin rev3: common questions
What microcontroller does the Eps-8pin rev3 use?
The Eps-8pin rev3 is built around the ESP32-C6-MINI-1-N4, from the ESP32 family.
How big is the Eps-8pin rev3 PCB?
The Eps-8pin rev3 measures 96 × 40 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Eps-8pin rev3?
63 components, from 31 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 Eps-8pin rev3 design files?
From the nathanfraske/CEC-Platform repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Eps-8pin rev3 design in my own project?
Yes, under the terms of its Apache-2.0 license, which nathanfraske chose for the repository.
Can I test firmware for the Eps-8pin rev3 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.
