- Main baseline: 554e4fe. The failed faf335b object was recoverable. Four PCB placement/source files were extracted, not cherry-picked; no housing work was recovered. - Real native KiCad Computer Use was available. C7 was moved in its properties dialog and two B.Cu 1.8V segments were interactively routed and saved. The attempted 0.25mm C7 move caused a courtyard overlap; C7 was manually returned to Y120.25 and zones refilled/saved. This attempt reduced 16 to 15 opens, without weakening any rules. - One…

Faf335b recovered: common questions

What microcontroller does the Faf335b recovered use?

The Faf335b recovered is built around the ESP32-C3-MINI-1-N4, from the ESP32 family.

How big is the Faf335b recovered PCB?

The Faf335b recovered measures 25 × 30 mm, has 4 copper layers and is 1 mm thick.

How many components are on the Faf335b recovered?

46 components, from 28 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 Faf335b recovered design files?

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

Can I use the Faf335b recovered design in my own project?

Yes, under the terms of its MIT license, which okbrainhq chose for the repository.

Can I test firmware for the Faf335b recovered 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.
