Ultra-small and easy-to-use current and voltage meter

Overview

This is a cloned and modified version of the simple ammeter project by @wffg, with only the PCB modified. Thanks to the open-source

project for its features:
ultra-small (only the size of a 0.96-inch TFT screen)
, minimalist design, no CC port (can be used as a meter head),
inexpensive, and needs no further explanation
. Notes on replicating:
When soldering the TFT screen, each pin needs to be soldered individually; the temperature should not be too high;
the back of the screen needs to be insulated; the windowed area needs to be tinned to meet overcurrent requirements.
For the BOM (Bill of Materials), please be sure to open the schematic and purchase the meter yourself.
Except for the sampling resistor, all resistors and capacitors use 0603 for easy soldering.
See the original project for more details.
