DSO138mini oscilloscope power module

Overview

## The main control of this small board is IP5306, 2.1A charging and discharging IC. It is a single-chip solution for power bank. A single inductor completes charging and discharging. It has current path management and can be charged while placing it.

## Installation renderings (soldered with rosin It has been used several times so it is dirty)! [IMG_20200703_203734.jpg]

### Built-in small battery (although it is only 700mah, the operating current of the oscilloscope is only 100ma, which is enough to carry it around for several hours)! [IMG_20200703_203702.jpg]

Need to do A little change (remove the D2 diode, otherwise it will automatically turn on when charging, and it will cause the input and output to short-circuit and burn). At the same time, I also changed the crystal oscillator to a thinner model. Although it is of no use at the moment, it may be installed in a larger size in the future. The big battery and crystal oscillator are really in the way.
