From the project
STM32F405 Flight Controller and NRF24 Transmitter
This repository contains the complete hardware schematics (KiCad) and flight firmware (C++/Arduino) for a custom-designed drone system. This project bypasses off-the-shelf flight controllers by using a scratch-built STM32F405 receiver board paired with a custom NRF24L01+ remote transmitter.
Hardware Architecture & Pinout: MCU: STMicroelectronics STM32F405RGT6 (Arm Cortex-M4, 168 MHz). Radio (Hardware SPI2): NRF24L01+ explicitly wired to PB13 (SCK), PB14 (MISO), and PB15 (MOSI) to prevent clock collisions with motor timers. IMU (Custom I2C): MPU6050 gyro/accelerometer mapped to PA5 (SCL) and…

Controller: common questions
How big is the Controller PCB?
The Controller measures 120.8 × 59.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Controller?
11 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the Controller design files?
From the Harshil200619/STM32-Custom-Drone repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Controller design in my own project?
The repository has no license, so all rights stay with Harshil200619. Use it as a reference, and ask the author before reusing the design.
