GPS board for the Avionics of a model rocket

This project is a RP2040, GPS board designed to be utilized in an avionics system comprising of 3 CAN connected PCBs which are comprised of a sensorboard, a powerboard, and a GPS Board. This avionics stack is designed for use in High Power model rocketry and aims to provide accurate telemetry, tracking position, altitude, and time during flight.

- L86-M33 -165 dBm GPS - Integrated Patch Antenna - CAN Transiecver - RP2040 - USB-C Connection - 5V -> 3.3V regulated power input - Onboard status LEDs for VBUS, MCU and GPS debugging - External 128Mbit Flash Memory

AvionicsGPS: common questions

What microcontroller does the AvionicsGPS use?

The AvionicsGPS is built around the RP2040, from the RP2040/RP2350 family.

How big is the AvionicsGPS PCB?

The AvionicsGPS measures 60 × 56.1 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the AvionicsGPS?

53 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the AvionicsGPS design files?

From the esb8/AvionicsGPS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the AvionicsGPS design in my own project?

The repository has no license, so all rights stay with esb8. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the AvionicsGPS 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.
