made from certified jellybean components!
- Jelly Bean Components
- Universal footprints
- All usefull gpios has been broken out to connectors
- Additional I2C expander
- Battery voltage measurement
- Integrated easy to solder BMS module footprint (HW341)
Board designed to allow manufacture of simple but capable wifi enabled robotics controller from most common avaliable components.
Board is designed to handle multiple packages of same components:
Also some components that are scarse or just rare to have in immediate reach are made bypassable by common ones:
Integrated easy to solder BMS module footprint (HW341)
!Warning! Due to me forgetting to add on/off switch after BMS it needs to be bodged in order to work:
