- OQ-9 (RESOLVED, v3.10 §6.13): PCIe transient capture is the analog DETECTION ladder above — Standard sees that a transient happened (binary, into FREEZE); magnitude/shape are held to the PCIe Pro/Max SKUs. (OQ-57..59 gate the details.) - OQ-10 / OQ-12: bundled-shunt vertical transition + high-current stackup for the ~40–55 A/cable shunt sites…

CEC PCIe 8-pin 2-Port Module: common questions

What microcontroller does the CEC PCIe 8-pin 2-Port Module use?

The CEC PCIe 8-pin 2-Port Module is built around the ESP32-C6-MINI-1-N4, from the ESP32 family.

How big is the CEC PCIe 8-pin 2-Port Module?

The CEC PCIe 8-pin 2-Port Module measures 86.4 × 44 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the CEC PCIe 8-pin 2-Port Module?

45 components, from 25 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 CEC PCIe 8-pin 2-Port Module 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 CEC PCIe 8-pin 2-Port Module 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 CEC PCIe 8-pin 2-Port Module 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.
