About the One connection remaining PCB

One connection remaining 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.

One connection remaining 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.

One connection remaining: common questions

What microcontroller does the One connection remaining use?

The One connection remaining is built around the ESP32-WROOM-32 (8MB), from the ESP32 family.

How big is the One connection remaining PCB?

The One connection remaining measures 79.8 × 79.8 mm, has 2 copper layers and is 0.8 mm thick.

How many components are on the One connection remaining?

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 One connection remaining 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 One connection remaining 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 One connection remaining 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.
