From the project

Open source flight controller based on the STM32F405 MCU that runs betaflight.

open-source (not that anyone would want to use it) 40x40 F405 Flight controller using betaflight software. ## Features

- 3 Universal UARTS - Dedicated pads for analog VTX - 9V and 5V Buck converters - 2x 3.3V LDOS - Integrated barometer - LDO and Buck converter status LEDS - 16MB Blackbox flash - Full betaflight support - ICM 42688-P (kind of a flex with how hard they are to get nowadays) - 4V5 Pads for RX

YecnodF405: common questions

What microcontroller does the YecnodF405 use?

The YecnodF405 is built around the STM32F405RGTX, from the STM32 family.

How big is the YecnodF405 PCB?

The YecnodF405 measures 40 × 40 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the YecnodF405?

116 components, from 54 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 YecnodF405 design files?

From the limiez1011/yecnodF405 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 YecnodF405 design in my own project?

Yes, under the terms of its GPL-3.0 license, which limiez1011 chose for the repository.

Can I test firmware for the YecnodF405 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.
