From the project
Barrel jack laptop power supply adapter module for framework laptops
This is a Framework laptop module designed to let you use Dell or HP laptop power supplies with a Framework laptop (or any other device that takes 20V USB-PD)
The schematic for this board was made by Arya, I tweaked it a bit and did the board layout. It requires an Altmode Friend, also made by Arya, to handle all the communication and control.
