README
README.mdThe Clampinator
Inspired by the ODrive Regen Clamp, the clampinator is a custom built regeneration clamp targeting 16-60V systems.
Key Features
- 16-60V input
- Adjustable clamp voltage via trimpot
- Full reverse current protection via TI's LM7481-Q1
- Ideal diode inrush current limiting supported, but marked as DNP
- External pre-charge resistor
- FULL galvanic isolation between power and logic domains
- USB-C port for programming
- STM32H5 based logic control
- Digital control to disconnect power input from output
- 2x CAN FD exposed w/toggleable termination resistors
- Two onboard LEDs (Yellow and RGB)
- Two 10k thermistor slots for thermistors
- Two 15V outputs for active cooling fans
[!CAUTION] The Clampinator must not be plugged in unless the power switch is off. To turn on, slide power switch to
PRECHARGE, and only proceed toRUNafter allowing at least 1s for the bulk capacitors to charge.
Using the CAN bus
The STM32 on the board is equipped with two built in CAN FD controllers, and the Clampinator has two accompanying CAN transcievers in the bottom left of the board. There is dip switch SW5 which can be used to toggle the internal 120Ω termination resistors.
Building the Clampinator
The Clampinator can be ordered from sites like JLCPCB. The KiCAD source files are in ./KiCAD and the production gerber files are in ./KiCAD/prod along with the bom.

Questions
How big is the Clampinator PCB?
It measures 200 × 115 mm and has 4 copper layers, 1.67 mm thick.
What parts does the Clampinator use?
211 parts, built around the MCP2562FD-E/P, TK100E10N1,S1X, PTS810SJM250SMTRLFS and SK6812MINI-E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Clampinator KiCad files?
From the AdrianR3/Clampinator repository on GitHub, at the commit this page was made from: the board is KiCAD/Clampinator.kicad_pcb and its schematic KiCAD/Clampinator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clampinator design in my own project?
Its repository states no licence, so its author keeps all rights: ask AdrianR3 before reusing the design.
