USB-POWER V1.2

PD deception uses INA226 for voltage and current detection, and a MOS tube for power output control; TYPE C input and output use XT30PW connectors.

PCB wiring is amateur, and netizens are welcome to give advice if there are any unreasonable ones!

There are currently bugs in V1.1, and V1.2 has been prototyped and awaits verification; except for the LCD screen and an input filter capacitor, all other PCB components are on the same side, and it is very convenient to use a heating table for soldering.

The casing still needs improvement. . .

2022/1/19 V1.2 has been verified and the software code is being sorted out. . .

2022/1/20 The code has been submitted, warehouse: https://github.com/OliverLuo1986/USBPD

Precautions:

1. C1 must be welded, and the withstand voltage must be greater than 20V. Failure to weld will cause the DC-DC chip to work abnormally.

2. Do not solder R7, otherwise it will cause failure to program.

3. When programming, press the middle button first, then power on, or short-circuit the EN and GND pads, and then download the program.

4. The positive and negative pins marked on the XT30PW female connector are exactly opposite to the pin definitions of the male connector on the board. Please pay attention when wiring.

The software is an Arduino project, developed based on LVGL. The code is very rudimentary and the interface is very simple. I would like to see if any netizens can help improve it.
