About the Before local repair PCB

Before local repair is an open source ESP32 PCB design by PNT2110, published on GitHub. It is a 2-layer board measuring 79.8 × 79.8 mm, with 72 components from 40 distinct parts.

Its main chip is the ESP32-WROOM-32 (8MB), from the ESP32 family. Other key parts include the MPU-6500, CH340C, USBLC6-2SC6, TPS63001DRCR and TPS61070DDCR. By type, the board carries 23 resistors, 20 capacitors, 9 connectors, 6 ICs, 6 transistors and 6 diodes.

It belongs with the robotics & motion, power & battery and sensors designs in this gallery.

From the project

An ESP32-WROOM-32 based flight controller designed for 1S brushed quadcopters.

An ESP32-WROOM-32 based flight controller designed for 1S brushed quadcopters.

The subsequent datasheet review found B.Cu tracks inside the ESP32 antenna region, power-layout concerns and incomplete flight features despite clean ERC/DRC. See BAOCAOKIEMTRAMACH.md and validation/datasheetaudit/LOGKIEMTRA.md`. The independent antenna check fails; do not interpret the routing checks below as proof that the design is ready to operate or manufacture.

Before local repair design files

The KiCad project lives in the PNT2110/FC_ESP32 repository on GitHub; these links point at the commit this page was built from.

Before local repair: common questions

What microcontroller does the Before local repair use?

The Before local repair is built around the ESP32-WROOM-32 (8MB), from the ESP32 family.

How big is the Before local repair PCB?

The Before local repair measures 79.8 × 79.8 mm, has 2 copper layers and is 0.8 mm thick.

How many components are on the Before local repair?

72 components, from 40 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 Before local repair design files?

From the PNT2110/FC_ESP32 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Before local repair design in my own project?

The repository has no license, so all rights stay with PNT2110. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Before local repair 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.
