As part of a research project aimed at testing and characterizing as many functions as possible of the RP2040 IC, I developed a compact, card-sized PCB with components placed on one side. This board's purpose is not only to test some of the RP2040's features but also to explore the integration of additional components like a GPS, a LORA module, and an IMU module in a compact design.

Instead of being a fully functional final product, this board serves as a test platform for various components to inform the design of future boards, while maintaining the functional shape of a 85x55x1mm contact card.
