MY-ETH001 Specification
The MY-ETH001 is equipped with a 30-pin FPC cable featuring on-the-same-plane wiring for interfacing with the FRDM-IMX91S board. The PIN1 of the J1 interface on the MY-ETH001 module corresponds with the arrow marking on the silk screen and should be connected in sequence to the PIN1 of the J4 interface on the FRDM-IMX91S board, as indicated by the arrow marking on its silk screen.
The MY-ETH001 Gigabit Ethernet module connects to the development board using its J1 connector via a Flexible Printed Circuit (FPC) connector. The J2 connector enables network connectivity through an RJ45 interface, which includes an integrated transformer. The pin assignments for the primary connectors are detailed in the accompanying figure.
