Flight Stick HW and SW files for the Falcon Aircraft

The STM32 MCU is programmed through ST-LinkV3 (SWD) and communicates via UART for debug and development. Differential USB data lines enable HID or COM functionality, depending on firmware.

Strain gauge signals are processed through a TI ADC, which triggers SPI reads via a DRDY interrupt. Processed values are sent to the servo controller board (via CAN) or USB interface.

Falcon flight stick: common questions

What microcontroller does the Falcon flight stick use?

The Falcon flight stick is built around the STM32F103CBU6, from the STM32 family.

How big is the Falcon flight stick PCB?

The Falcon flight stick measures 76 × 51.5 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Falcon flight stick?

55 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Falcon flight stick design files?

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

Can I use the Falcon flight stick design in my own project?

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

Can I test firmware for the Falcon flight stick without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
