About the Pcie3-rev2-routed PCB

Pcie3-rev2-routed 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 103.4 × 44 mm, with 54 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, LP5907MFX-3.3, INA238AIDGSR, INA238 and INA181A2IDBVR. By type, the board carries 19 capacitors, 12 ICs, 8 resistors, 2 connectors, 2 switches and 2 diodes.

CEC is a modular PC power-telemetry system. Per-rail sensing modules connect to a central Hub over a single commodity cable (RJ-45). The Hub aggregates telemetry and forwards it to the host PC over USB. Four tiers — Standard, Pro, Enterprise, Mission Critical — are built from one fundamental design with progressively populated features.

Modules are tier-agnostic and degrade gracefully: any module works in any Hub, with higher-tier features going dormant when the Hub cannot service them and activating, without replacement, when the module is moved to a capable Hub.

Pcie3-rev2-routed: common questions

What microcontroller does the Pcie3-rev2-routed use?

The Pcie3-rev2-routed is built around the ESP32-C6-MINI-1-N4, from the ESP32 family.

How big is the Pcie3-rev2-routed PCB?

The Pcie3-rev2-routed measures 103.4 × 44 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pcie3-rev2-routed?

54 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 Pcie3-rev2-routed design files?

From the nathanfraske/CEC-Platform repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Pcie3-rev2-routed 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 Pcie3-rev2-routed 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.
