Description

This is a power supply for powering a zoom F8-Fn or similar audio recorder from a lithium battery such as the NP-F970.

This pcb requires an arduino or similar microcontroller connected to a display (an oled was used for the original version) via i2c.

This is a slightly modified of my first version, with the addition of a ground plane on the bottom of the pcb.

I have evolved this design a bit since the original, and will likely share those designs as well.
