Case for USB RFid reader

thingiverse

This is a case for a cutting-edge USB RFID reader module known as the "134.2Khz RFID ISO11784/85 FDX-B EMID MINI Module" that can be found on https://www.aliexpress.com/item/134-2Khz-RFID-ISO11784-85-FDX-B-EMID-MINI-Module/32717871216.html. The module comes with the antenna conveniently attached to the PCB via a simple tape. This case relocates the antenna away from the PCB, which is likely an advantage, and also makes the entire assembly more robust. Printing and assembly should be straightforward processes. The lid can be secured using a small countersunk screw. It might be a good idea to add a small piece of soft foam material to support the antenna for optimal performance. The module itself features a NUC122LD2 Arm-based microprocessor from Nuvoton. Although there is limited information available on how to use it, it appears that the module functions as a USB keyboard device and sends keycodes corresponding to detected RFID IDs after emitting a brief LED flash followed by a return key.
