The most beggar 17+4 PAD modified version

Modified from the third generation of Lettuce, the firmware is universal.
 
The changes are as follows
1. The location of the USB-A port has been modified, and the number has been changed from 3 to 1.
2. Modified the positions of 4 additional buttons.
3. Removed touch.
4. The interface is changed from micro usb to type-c
5. The position of the screw hole is changed.
 
Since I don't know how to write firmware, the lights of the four additional buttons use resistors to reduce the voltage. Those who are capable can modify the firmware themselves.
Comes with 3D shell model, which has been verified. (I didn’t paint the casing well, it’s a bit bad. Don’t complain about my painting skills.) There are reset holes and positions for anti-slip stickers. The shell comes with an inclination angle of 6 degrees
(the nuts are M2.5*3.8*3. Since I don’t like to iron the nuts in with a soldering iron and prefer to use glue to bond them, the nut mounting holes are a bit large. If you need to iron the nuts, you can Modify the 3D model drawings yourself)
