v2.2
The motor controller
Aotenjo One
Bring smooth, precise motion to your robotics and DIY projects with a compact BLDC field-oriented control board.
- DRV8313 motor driver
- 14-bit encoder interface
- CAN FD · switchable termination
Hardware for hands-on builders
Put your ideas in motion.
Build your own automation machines with motor control boards, open source code, and practical guides. Start with one motor. Grow into a whole machine.
AOTENJO / ONEV2.2
Open source software Connected over CAN FD From wiring to working code
01 / The boards
One motor. Or a whole system.
Two boards, built to work together. Drive each motor with One, and coordinate them with Master.
v2.3
The system coordinator
Aotenjo Master
Connect your PC to a network of motor controllers. Send commands, receive feedback, and bring multiple axes together.
- USB Type-C connection to your PC
- Dual CAN & power connectors
- Place at either end or mid-bus
02 / Built with Aotenjo
Real hardware. Real work.
ONE + MASTER
A machine that makes motors.
Our BLDC motor winding machine puts One and Master to work together, turning drone motors into gimbal motors. Explore the build, the code, and what we learned along the way.

Why Open Source Hardware is Hard
Open source software has changed the world-but can the same model work for hardware? I'm not so sure.
Automate Your Physical Work
During COVID, many desk workers experienced the comfort of working from home-something that physical laborers couldn't enjoy. Ironically, those same desk jobs are now the first to be automated by AI.
Selling the Machine as a Kit
I've decided to sell the BLDC motor winding machine as a kit for people who want to build one themselves.
Gimbal Motors for Robotics
Gimbal Motors are great for robotics projects. They are smooth, precise, and powerful at low speeds.
Lack of Gimbal Motors
I've been working on building a motor winding machine for over two months. The primary reason I started this project was that I wanted to create a gimbal motor for robotics projects.
Why We are Building a DIY Winding Machine
I bought this inexpensive mountain bike from Amazon last April for 23,480 yen (about $153). Funny enough, it ended up giving me an idea for the winding machine project.
