2025/10/15 update:

A user asked for source file to remix so I've added Fusion360 file.

---------------------------

I really like this board as it provides 65w PD fast charge (Max 20v 3.25a) in a really small package. This is what I came up with to use it in my backup battery pack.

• You can mount the board after installing this mount
• Include cutout template
• After installing the board, secure it in place using 1.75 filament (softer ones like TPU or PETG preperably), your smallest zip-tie, or a metal wire often used to bind cables. (refer to 2nd attached photo)

CKCS U1E board specs:

• Input: 8-30v
• Output: 5v3a, 9v3a, 12v3a, 20v3.25a
