PD-QC protocol decoy

There are power banks and fast charge chargers, but! It is unfriendly to only support the corresponding protocol handshake to output the corresponding voltage. How can we limit the omnipotent ability of our DIY enthusiasts? We must tell the manufacturers with facts that that is impossible. Using it to the extreme is the spirit of DIY. Let's completely squeeze out the power bank. It's simple. It can be turned into a power bank in seconds. You don't have to worry about it.

ATOM-PD143 is actually just the name of my project. Don’t care too much. You can change it as you like when you get the file. To put it simply, this stuff is used for development and testing of PD/QC adapters, PD/QC mobile power supplies, etc., as well as production line testing and The aging test equipment can negotiate with the adapter or mobile power supply through PD/QC communication to induce the output of the corresponding voltage. The board uses a 4-layer PCB design including 2 negative layers. With our Jialichuang, the four layers are also cheap. , it’s not a big deal, it’s not a waste of money, but the buttons are a bit expensive. Considering the need to frequently adjust the output voltage level, I used SMK buttons. If my rich friends can just buy the original ones, it’s not a waste of money. The PD has a fixed output voltage level. 5V, 9V, 12V, 15V, 20V, PPS voltage regulation range, maximum output power 100W, all project files are shared, schematics, PCB, BOM, GerBer, assembly drawings, firmware needs to be burned, I will also send the burning tools Go up, the project is mass-produced after verification, and the burn-in test, the hardware is updated to version V1.1, I will not talk about the sad development process, it is an absolute productivity tool, simple, easy to use, original project, I am a novice and dare not interact with it Big brother, please feel free to leave me a message if you have any questions. I would like to trouble my friends and give them a thumbs up. My N hours of hard work are not in vain.
