About the Main ctrl esp32 servo PCB

Main ctrl esp32 servo is an open source ESP32 PCB design by Spectating101, published on GitHub under the MIT license. It is a 2-layer board measuring 80 × 50 mm, with 11 components from 11 distinct parts.

Its main chip is the TXU0304PWR, from the ESP32 family. Other key parts include the W25Q128JWSIQ and TLV75518PDBVR. By type, the board carries 4 connectors, 3 ICs, 2 capacitors and 2 resistors.

It belongs with the robotics & motion designs in this gallery.

From the project

Auditable hardware bring-up: donor → KiCad carrier + DRC + bench gates → PROJECT_PACKAGE. Seeking 3 design partners.

Software that runs the checks a hardware engineer would run before a circuit board is built, and packages the result so anyone can rebuild and verify it.

The SPI flash adapter reference design: a routed two-layer board with 18 test points, produced and checked through the workflow.

Hardware Splicer takes a board design through KiCad electrical and design-rule checks, a bill of materials and fabrication-file check, and a staged list of what must pass before bench work begins. An AI agent can do parts of the engineering, but only through those same checks: a model's suggestion never becomes a…

Main ctrl esp32 servo: common questions

What microcontroller does the Main ctrl esp32 servo use?

The Main ctrl esp32 servo is built around the TXU0304PWR, from the ESP32 family.

How big is the Main ctrl esp32 servo PCB?

The Main ctrl esp32 servo measures 80 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main ctrl esp32 servo?

11 components, from 11 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 Main ctrl esp32 servo design files?

From the Spectating101/hardware-splicer repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Main ctrl esp32 servo design in my own project?

Yes, under the terms of its MIT license, which Spectating101 chose for the repository.

Can I test firmware for the Main ctrl esp32 servo 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.
