The typec adapter board uses 0.8mm thick.
Other boards of 0.8mm and 1mm will work.
This solution has flaws, overall The power consumption is large and cannot be turned off manually. The phone runs out of power after 12 hours of standby.
The temperature of the board is relatively high when charging and the power cord is narrow, but there is no major problem after using it for a few days.
 
LDR6028 has a flaw. Disconnect the power cord USB when charging. The signal will be disconnected, which will
have a great impact on the game in the card reader.
 
The shell files use JLC's 3D printing service.
The joystick uses NS joycon joystick
buttons. In addition to the printed parts, a set of ndsl buttons is also required, of which the A button is limited. The bit ring needs to be cut
and assembled with screws: m1.4*5 and m1.7*8.
The assembly is not so tight. Do not tighten the screws too tightly.
You need to buy a 3.5mm high version for the start and select buttons. Other buttons require 5mm
