Charging pogo pinout - diy replacement of dock

I want to make myself a charging dock out of the box the headset came in but I'd need to know the pinout and possible handshake I would need to mimic. Could anyone who has the dock measure the voltages and see/record and communication over the data pin?

Questa è una buona domanda?

i want to know the same thing as well, i already use a magnetic usb c cable but a dock would be nicer

Me too please. Can someone take a meter to one of these docks a tell us what the pinout is?

Just waiting for someone... anyone, to buy the dock 😆

Hi.

Did you ever make one? if so did you 3d print it, and can you share the files?

and the schematic.

thank you

靠近中间的PIN是GND,靠近外部的PIN是+5V,中间的PIN通过改变对地阻值反应充电状态。我使用这个定义并完成了电路部分的demo设计。可惜的是我不擅长结构建模。

只要你保证电压是5v,就不用担心简单的反接测试会烧毁设备,因为我已经试过了lol

I don't know Chinese, please let me know if you'd prefer me to use some translator.

The inner pin doesn't matter in this case? It's enough to provide 5V to the outside pin and ground to the middle one? I tried doing this with some USB charger cables without luck back when I posted the question.

The PIN near the middle is GND, and the PIN near the outside is+5V. The PIN in the middle reflects the charging state by changing the ground resistor value.

use a 10k pull up resistor link to the pin in the middle pin. 5v means NO CHARGING, 1.7 means CHARGING.

da

The inner pin just a indicator for charging state. if I am right.

official accessory page says:

USB-C Input 9V/12V/15V

Contact Output 5V/9V/12V

so there seems it suppport charing at a higher voltage

Connect the wires, red to red and black to black and add a type A port to charge it

HI.

Did you ever make one? And if so, did you 3d print it and can you share the files. I think i have a schematic but could you share what you have?

I think the same for the magnetic port. My homemade battery works
