HeyPCB/kestrel-gpsKestrel GPS: u-blox MAX-M10S under a 25 mm ceramic patch with an LIS3MDL compass, for Betaflight, INAV and ArduPilot. 28 x 28 mm 4-layer KiCad 10 board, DRC clean, with gerbers, BOM, CPL and STEP.
Kestrel gps is an open-source printed circuit board by HeyPCB, from the HeyPCB/kestrel-gps repository on GitHub, published under the CERN-OHL-S-2.0 licence. It is a 4-layer board of 28 × 28 mm with 14 parts on 21 nets, routed with 116 tracks and 54 vias.
It is built around the MAX-M10S-00B, LIS3MDL and XC6206P332MR-G, with the CL21A106KAYNNNE and SM06B-SRSS-TB(LF)(SN) among its other parts. Its parts include 8 capacitors, 3 ICs and 1 connector. It belongs with the radio and wireless and robots and motor control boards of this library.
A u-blox MAX-M10S under a 25 mm ceramic patch, with an LIS3MDL compass, on a 28 x 28 mm board that plugs 1:1 into the Kestrel H7.
The Kestrel GPS is the navigation module of Kestrel. Its top face is unbroken ground for the patch antenna, whose feed pin passes through a plated hole to one 2.5 mm track to the receiver; every part is on the bottom face. Betaflight, INAV and ArduPilot all have drivers for both chips.
| Layers | Size | Footprints (LCSC parts) | Nets | Connections routed | Routed vias | ERC errors / warnings | DRC errors / warnings / unconnected / parity | Parts per board, 10-board build |

Not fabricated, assembled, powered or flown yet. Every number on this page is measured by KiCad
10.0.6 on the files in this repository (report.json, fab/erc.json,
fab/drc.json) or read from the live JLC/LCSC catalogue (bom_cost.md:
parts only, at a 10-board build's price tier with JLC's Extended-part fee; the bare PCB and assembly are
quoted at order time).
The 1 ERC warning is KiCad's pin-type check on a pin the design ties to a rail on purpose: the LIS3MDL's SA1 tied to Vdd_IO selects I2C address 0x1E.

4 layers, 1.6 mm, 1 oz copper; parts on the bottom face only (the top is the antenna's ground). Upload fab/kestrel_gps_gerbers.zip, fab/kestrel_gps_bom.csv
and fab/kestrel_gps_cpl_jlc.csv to JLCPCB: every part has an LCSC number.
Bring-up, one board at a time, is in the hub's BUILD.md.
Designed with the HeyPCB method on KiCad 10.0.6, headless, by the heypcb-kicad pipeline: a written brief composed from reusable circuit blocks, every pin from KiCad's own symbol library, every part bound to an LCSC number from a dated catalogue read, then ERC, a netlist round trip, locked placement, Freerouting 2.4.1, pours and stitching, silkscreen, DRC with schematic parity, DFM and a fab gate, each stage gated by a measurement. design/make_brief.py regenerates the brief (outline, part locks, net
classes) from code.

14 parts, built around the MAX-M10S-00B, LIS3MDL, XC6206P332MR-G and CL21A106KAYNNNE. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the HeyPCB/kestrel-gps repository on GitHub, at the commit this page was made from: the board is kicad/kestrel_gps.kicad_pcb and its schematic kicad/kestrel_gps.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
