🛠️ I'm designing my first ever PCB (printed circuit board) 🔄 to create an ESC (electronic speed controller) for a drone 🚁 I plan to build. This ESC needs to handle a continuous current of 40A with short peaks of 50A ⚡. It's designed to work with 3S to 6S batteries 🔋.

At the heart ❤️ of the device, I'm using an STM32G431 microcontroller 🧠, chosen for its performance and price (samples available for students 🎓). I've also added:

- DRV8320 MOSFET driver 🔌

- AP63203WU-7 fixed buck converter (1A output) 🔌

- CSD88584Q5DC all-in-one half-bridge 🌉

These components power the MCU, driver, RGB LED 💡, I2C connector 🔌, and other peripherals.

This project is a great way to learn about:

- PCB integrity 💻

- EMI (electromagnetic interference) 📡

- Circuit design ⚡

- Electronic speed controllers 🎛️

But it comes with big challenges 💪! It's complex but exciting 🚀.

Currently, the PCB is ready with all the components soldered and I've only just started working on the code and I did make a test code to test the I2C part using an oled display and it works like a charm!

Also some components are not the same between the BOM the schematics and its because some components were in stock, I've put some alternatives to those that weren't in stock. I plan to release a YouTube video about the project soon on my channel, Nayel KHOUATRA. Stay tuned!

Here is a first video just to show my first attempt to test the board :
