Gaia obc stencil: common questions

What microcontroller does the Gaia obc stencil use?

The Gaia obc stencil is built around the ESP32-S3-PICO-1-N8R2, from the RP2040/RP2350 family.

How big is the Gaia obc stencil PCB?

The Gaia obc stencil measures 0.6 × 9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gaia obc stencil?

161 components, from 45 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gaia obc stencil design files?

From the onionsat-pcbs/gaia-obc repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Gaia obc stencil design in my own project?

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

Can I test firmware for the Gaia obc stencil without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
