From the project
This is a copy of the PROVES Kit FCV5dProductionRev2 flight controller (github.com/proveskit/flightcontroller_board, commit 2a7c1ec).
This is a copy of the PROVES Kit FCV5dProductionRev2 flight controller (github.com/proveskit/flightcontroller_board, commit 2a7c1ec).
Note: the repo also has an earlier FCV5dProduction folder. That revision ties U13 EN to VBUSP through R125, so the 5 V rail is always on. Rev2, the base used here, pulls EN up to +3V3 instead and lets MCP23017 GPB6 (~5VRESET) control it. This board changes R125 to a pull-down. The on-board radios have been replaced by an interface to the AMSAT LTM-1**, which provides all communications for the 1U CubeSat.

What microcontroller does the FC V5d LTM mods 20261010 use?
The FC V5d LTM mods 20261010 is built around the RP2350_60QFN, from the RP2040/RP2350 family.
How big is the FC V5d LTM mods 20261010 PCB?
The FC V5d LTM mods 20261010 measures 88 × 94.5 mm, has 4 copper layers and is 1.626 mm thick.
How many components are on the FC V5d LTM mods 20261010?
280 components, from 106 distinct parts. The full bill of materials is listed on this page.
Where can I download the FC V5d LTM mods 20261010 design files?
From the dpiresearch/claude_flight_board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the FC V5d LTM mods 20261010 design in my own project?
The repository has no license, so all rights stay with dpiresearch. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the FC V5d LTM mods 20261010 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.
