About the Oapogee.space PCB

Oapogee.space is an open source RP2040/RP2350 PCB design by Xaxis, published on GitHub under the CC-BY-SA-4.0 license. It is a board, with 49 components from 36 distinct parts.

Its main chip is the RP2350A, from the RP2040/RP2350 family. Other key parts include the MCP73831, TPS63001, W25Q128JVSIQ, BMP390 and ICM-42688-P. By type, the board carries 13 resistors, 12 capacitors, 9 ICs, 5 connectors, 3 switches and 3 inductors.

It belongs with the rf & radio and test & measurement designs in this gallery.

From the project

Open source telemetry payload for model rockets: altitude, acceleration and orientation logged onboard, with a live LoRa downlink and GNSS recovery tracking. Plus the documentation that teaches you to build one.

An open source telemetry payload for model rockets, and the documentation that teaches you to build one. Site at oapogee.space.

oApogee records altitude, acceleration and orientation through a flight, logs it to onboard flash, and optionally downlinks it live over LoRa and reports GNSS position for recovery. It attaches to a rocket you already own, in a printed pod that needs no modification to the airframe.

Oapogee.space: common questions

What microcontroller does the Oapogee.space use?

The Oapogee.space is built around the RP2350A, from the RP2040/RP2350 family.

How many components are on the Oapogee.space?

49 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the Oapogee.space design files?

From the Xaxis/oapogee.space repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Oapogee.space design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which Xaxis chose for the repository.

Can I test firmware for the Oapogee.space 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.
