STM32 ESC PCB Schematic Design - KiCAD ESC Project (DeepDrive v1.0)

This is the first version of the DeepDrive project, an STM32-Based ESC PCB Designed For Evaluating Motor Control Algorithms for PMSM/BLDC Motors. I’ve designed this board to be a development board that can be used to test various motor control algorithms, especially Sensorless FOC (Field-Oriented Control).

In this video, I'll show you the STM32 ESC PCB & schematic design steps, explain some of the design decisions that I’ve made, how to prepare the files needed for manufacturing, and how to place the PCB SMT order at JLCPCB who are kindly sponsoring this project as well.

I am so fortunate to have found this helpful video. I was completely overwhelmed by the lack of videos covering this topic. 
Thank you, Khaled.

[DeMaxize]

amazing, waiting for more !
this type of videos are gonna blow up, very good

[retronexusnet]

amazing content! I hope you will produce more videos like this

[dhruvbose]

Superb explanation! Eagerly awaiting the PCB layout and routing followup video.

[mustafa_mah]

ما شاء الله عليك يا خالد
ربنا ينفع بك ويوفقك ❤

[dhairyapanchal]

I'm developing ESC for ebike and found your video its very helpful and guided through my mistakes and helps me a lot if I just changed the FETs to drive at higher voltage along with power sections it's possible to implicate same configuration of your circuit for my project.

Waiting for your follow-up video related to drivers and testing 😊

[kulaniscap]

Give us more videos - this is really good work.

[davidbalderrrama]

Amazing video. Thank you for posting this!

[amerhk]

An Amazing video!! waiting for more similiar videos.

[phutan]

may I ask how you calculate the series gate resistor for the mosfet to be 22ohm?

[rizqokarim]

hello, do you know about the sizing of capacitor and inductor for the bridge filter and bulk capacitor? thanks

[sanjikaneki]

how is V2 going? also is the code finished?

[eelcohoogendoorn]

Thanks, this is a really excellent level of detail, very educative for the level of knowledge I am at. Would be great to see someone go over firmware written for educational purposes as well. As much as I like VESC I cant say the code was very much written to be read.

[nimasalehi]

is there any software coding design video released yet for this project? will you do it?

[kumaylmoosavi]

Amazing guide to BLDC motor driver. Thankyou!
I just have a some small questions, any way you can guide would be very much appreciated
a) What maximum current rating of a BLDC motor this driver can drive?
b) What changes would you suggest I look into to make it a 24V DC supply operated system
c) Can you share or make a video on the firmware that you developed in this video at the end for the six step commutation system? Did you use an FOC algorithm?

[mohamedsafy]

Amazing content as always and looking forward to hear about the consolidated version for cheap skates folks LOL !
I had a question tho regarding the shipment, duty fees and taxes on such boards in Egypt, and was it a smooth process importing such board ?

[giantbee]

Hello! How's the project going? :) Any updates? :D Thanks for the video comprehensively walking through your thought process!

[TrilokSawant-pzsn]

how to download schematic ? it is asking password for drive

[zakhoover]

Did you post your microcontroller code/walkthrough it anywhere?

[damianwiecaw]

Why didnt you use DRV built in buck converter?
