Flight-Data-Computer: common questions
What microcontroller does the Flight-Data-Computer use?
The Flight-Data-Computer is built around the C969151, from the ESP32 family.
How big is the Flight-Data-Computer PCB?
The Flight-Data-Computer measures 86 × 165 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Flight-Data-Computer?
125 components, from 29 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Flight-Data-Computer design files?
From the Ethan-Poag/Flight-Data-Computer repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Flight-Data-Computer design in my own project?
Yes, under the terms of its GPL-3.0 license, which Ethan-Poag chose for the repository.
Can I test firmware for the Flight-Data-Computer without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
