I have made great progress on my RP2350 powered open source brushless motor (and industrial stepper) controller! This board supports up to 53v max, 30+A peak (depends on thermals), and is designed so anyone can order them from JLCPCB. I also just added USB-PD for 100W at 20V via USB-C!

I get these plastic containers from Michaels (craft store.) They are great for organizing your #hacking tools. I use one for tools and one for interfacing/connection. You can fit a lot in each one. #Glasgow #bruschetta #jtagulator #Tigard #AnalogDiscovery
