MAXREFDES300#: RFID data logger for healthcare and cold chain logistics

The MAXREFDES300# reference design allows the user to prototype a product to measure and log temperature for the healthcare industry and cold-chain logistics.

The major components on the board are Maxim’s MAX32660 microcontroller, Maxim’s MAX20310 PMIC, and Axzon’s Xerxes™ RFM405 wireless sensor. Combined with the RFM405, the MAX32660 provides an evaluation board to overcome the challenges faced by current dataloggers by wirelessly reading/writing, providing traceability of temperature violation, improving battery life, and reducing cost. The reference design has a standards-compliant UHF interface (EPC Gen2v2) which easily allows a compatible RFID reader to communicate wirelessly.
