About the Aerocore PCB

Aerocore is an open source STM32 PCB design by msamikassem, published on GitHub under the MIT license. It is a 4-layer board measuring 36 × 36 mm, with 50 components from 31 distinct parts.

Its main chip is the STM32F411CEU6, from the STM32 family. Other key parts include the LMR51430, TLV75533PDBV and BMI270. By type, the board carries 18 capacitors, 13 connectors, 9 resistors, 4 ICs, 4 diodes and 1 crystal.

It belongs with the robotics & motion, sensors and power & battery designs in this gallery.

From the project

Flight controller for 3-inch FPV drones, built around an STM32F411 and BMI270 IMU. Custom 4-layer PCB with power regulation, IMU, USB-C, and 4-motor ESC control.

Aerocore is a flight controller for 3-inch FPV drones, built around an STM32F411 microcontroller and a BMI270 IMU. It handles IMU sensing, ESC motor control, USB configuration, and power regulation from a 4S LiPo on a single 4-layer board.

- Runs an STM32F411CEU6 (Cortex-M4, 100MHz) as the main flight computer - BMI270 6-axis IMU over SPI for gyro/accel - USB-C mainly for serial communication with a PC - Powers itself from a 4S LiPo, steps down to 5V (buck) and 3.3V (LDO) on board - Drives 4 ESCs via PWM - UART header for an ELRS receiver - Dedicated ST-Link header for programming/debugging…

Aerocore: common questions

What microcontroller does the Aerocore use?

The Aerocore is built around the STM32F411CEU6, from the STM32 family.

How big is the Aerocore PCB?

The Aerocore measures 36 × 36 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Aerocore?

50 components, from 31 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 Aerocore design files?

From the msamikassem/Aerocore 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 Aerocore design in my own project?

Yes, under the terms of its MIT license, which msamikassem chose for the repository.

Can I test firmware for the Aerocore 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.
