A replacement blade controller for lightsaber blades from Galaxy’s Edge. Firmware and documentation about this project can be found on the project’s github repository.

The links provided in the BOM below are only examples of components that would work. They are unaffiliated and not an endorsement of any specific component provider.

It is possible to reuse the transistors and SOT-23 LDO off a stock blade controller with this PCB.

It is also fine to use a 1 kOhm resistor at R8 instead of 10 kOhm if you wish to simplify things a bit.
