+## Thanks
 Thanks to many respectful guys/companies who made their tools or materials free or open source (KiCad, OnShape, InkScape, Fritzing, Raspberry things), ChatGPT and GitHub Copilot helped a lot as well.
 
-And thanks to community developers that inspired me and helped me: CrazyRedMachine (https://github.com/CrazyRedMachine) for the Spicetools Card IO part, Sucareto's AIME Reader (https://github.com/Sucareto/Arduino-Aime-Reader) for the AIME protocol part.

+If you opt for the PN5180 NFC module, note that the housing design is up to you. Ensure it fits your design or you can use it without a case. Be prepared to solder more wires compared to the PN532 version.

+## Building "AIC Key"
 AIC Key is a variation of the AIC Pico - a keypad is integrated. Much more difficult to build than the "AIC Pico" as it has many tiny components to solder.
