Overview
Carrier rev a is an open-source printed circuit board by rhine59, from the rhine59/ESP32-EFIS repository on GitHub. It is a 4-layer board with 25 parts on 50 nets, routed with 242 tracks and 115 vias.
It is built around the ESP32-S3-WROOM-1-N16R2. Its parts include 7 connectors, 5 capacitors, 5 resistors, 3 ICs and 1 inductor. It belongs with the ESP32 boards of this library.
Main components
1README
hardware/kicad/carrier_rev_a/README.mdCarrier PCB Revision A
KiCad 8-compatible project for the ESP32 Artificial Horizon custom carrier.
- 68 mm circular 4-layer PCB
- ESP32-S3-WROOM-1-N16R2
- TPS62162-Q1 3.3 V buck
- MCP23008 control expander
- USB-C 2.0 device/power input
- direct 40-pin Newhaven FFC
- BMI088, encoder and TPS61169 interfaces
- 60 mm mounting-hole PCD
This is a prototype hardware revision for bench validation. It is not flight-qualified hardware.
Testability and production follow-on
Revision A remains a bench PCB, but bring-up should preserve access needed by the bootable electrical test harness: power rails, reset/boot, display/backlight controls, MCP23008/encoder and sensor interfaces. The later production carrier adds protected nominal 12 V aircraft power conversion, encrypted-NVS-capable firmware configuration, GNSS and protected external DATA/EXPANSION interfaces. Do not expose raw ESP32 GPIO as aircraft-voltage-tolerant connections.

Questions
What parts does the Carrier rev a use?
25 parts, built around the ESP32-S3-WROOM-1-N16R2. 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.
Where can I download the Carrier rev a KiCad files?
From the rhine59/ESP32-EFIS repository on GitHub, at the commit this page was made from: the board is hardware/kicad/carrier_rev_a/carrier_rev_a.kicad_pcb and its schematic hardware/kicad/carrier_rev_a/carrier_rev_a.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Carrier rev a design in my own project?
Its repository states no licence, so its author keeps all rights: ask rhine59 before reusing the design.
