EVAL-CN0575-RPIZ is a 4-layer printed circuit board (PCB) that allows evaluation of the CN0575 10BASE-T1L field device development platform with Class 12/13 Single Pair Power over Ethernet (SPoE). Designed for use on the Raspberry Pi platform, the CN0575 hardware features a 40-pin GPIO header, and follows the same mechanical dimensions as a standard HAT. To allow board stacking and development of field device applications using Raspberry Pi HATs, an additional GPIO header with extended leads is included with each evaluation board. However, the CN0575 can also be used on its own as a basic temperature sensing field device with remote user input/output via an onboard button and LED.
