They current layout contains an SD Card at the top and a micro USB connector on the right hand side of the PCB (as viewed in the PDF). The job consists of the following: 1a) move the SD card next to the micro USB connector 1b) if needed move the mounting point next to the micro USB connector to make space 2) replace the connector with a different variant (IP67) one, STEP and drawing included 3) p...

We currently have a designed and tested anchor PCB for an RTLS system. This design uses two DWM1001C Modules, one for anchor mode (get a reference for fixed position) and a bridge mode (getting data from mobile devices) and we are having poor range with both modules compared to the development boards. The job main activities include: 1.- Choosing proper enclosure (IP67) for this RF design. 2.- Ch...
