Basics
- An open source Motor Controller designed to turn hobby brushless dc motors into brushless dc servo motors
- Thus open source and/or hobby level products can use these instead of stepper motors and have the advantages of servo motors
- According to This it is no longer open hardware, only software post v3.4 ?
- How cheap can this be made assuming diy (milled/etched) pcb's ? OTS is ~159.00USD for the board
- Need to find an older BOM, and do some guestimation
- Also can it be scaled up/down in motors/board, current is two motors per board
- ie small single on-motor board, piles of motors for a single board -> cnc machine application etc

OSE Replication
Basic Process
Phase 1
- Purchase Board
- Dowload Software, get familiar with it, and find the best software
Phase 2
- Scale Circuitry up to something that can be Milled , or something that can be etched using a pen plotter based mask as well as easily soldered
- Get OSE Board Working to the Same Specs
Phase 3
- Move on to higher specs (higher voltage etc)
- Use OSE Motors
- Make it integrated with the servo motor in a 3d printed or cnc machined case
Phase 4
- Make a workbench in KiCAD to allow adding footprints of an ODrive Module to a Custom PCB on a per - servo basis
