Ladispad is a custom-made 11 key macropad with 2 rotary encoders designed for the simplicity and the ease of assembly to non technical users.
Ladispad uses a direct pin approach, no no need to solder diodes.
In addition, the 2 rotary encoders and the OLED screen are optional.
What I like about this PCB is that it allows you to use non-standard size Pro Micros too:
Ladispad uses a Pro Micro as its main controller. Its very affordable and have many variants with different USB ports and sizes. I designed the PCB so it will be compatible which whatever you choose – ajmandourah.
