Open mesh-phone.kicadpro in this directory. The project in ../main/` is the preserved original, not this corrected revision.

- MAX-M10S GPS with passive-antenna U.FL, UART, PPS and bypass capacitors. - Rear keyed 10-pin JST-GH expansion interface, with a current-limited 3.3 V supply and shared SPI/I²C. Switch off and disconnect USB before swapping. - MCU EN/BOOT support, usable SPI pin assignments, keypad expander pin-order corrections, display controls and I²C pull-ups. - Removal of the switch connection that directly joined USB 5 V to the battery. - Reconciled schematic/PCB pad contracts…

Owasso1-unrouted: common questions

What microcontroller does the Owasso1-unrouted use?

The Owasso1-unrouted is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the Owasso1-unrouted PCB?

The Owasso1-unrouted measures 87 × 154 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Owasso1-unrouted?

95 components, from 80 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 Owasso1-unrouted design files?

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

Can I use the Owasso1-unrouted design in my own project?

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

Can I test firmware for the Owasso1-unrouted 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.
