Reposting from the MCU general:

Are there any simplifications I can make on this power supply circuiit?
- I am wondering if it is safe to drop D1
- I think I could drop R4 and connect DC level to pin 3 of the Barrel_Jack_Switch and use an internal pullup. Never tried using this pin before though.
- Anything else a smart anon may notice.

R1 and R2 are required because I don't want to buy more resistors and BAT_LVL will be attached to a 3.3v ADC.

Hello friends. Are there any simplifications I can make on this power supply circuiit?
- I am wondering if it is safe to drop D1
- I think I could drop R4 and connect DC level to pin 3 of the Barrel_Jack_Switch and use an internal pullup. Never tried using this pin before though.

R1 and R2 are required because I don't want to buy more resistors and BAT_LVL will be attached to a 3.3v ADC.
