Thank you Réstep
The EMI filter circuit included in the Rotary Tool PCB is based on Chris Arntzen’s openly licensed Réstep EMI Filter add-on for older versions of FarmBot’s vacuum pump.
Thank you Chris for lending your expertise in electronics design to the FarmBot community with this fantastic open-source contribution!
