1. Normative Document

uEMC conform to the standard of EN 50121-3-2:2006;

uEthernet complies with the standards of IEC61375-2-3:2015 and IEC61375-3-4:2014

2. Electrical Parameter

Unless otherwise stated, the parameters listed in the following table refer to values at Tamb=25 ° C.

3.Mechanical Dimension

                                                            Top View

The external mechanical dimension (expressed in metric units) as above drawing, which specifies the length, width, height of the product, and part of the mechanical structure. Users can refer to the positioning parameters (expressed in metric units) accord it if they need to make the NETMODSin A7 baseboard (motherboard). The distance between the rows of needles is 40.64mm (1600 mil), and the spacing between needles is 2.54mm (100 mil).

4. Pin Description

* Note: Please leave the reserved pin to be NC! When connect with MCU, TXD1 and RXD1 should be cross-connected.

The reset pin of the nRST should be pulled down at least 500ms before it can be reset, and then it needs to maintain the high level   2000ms before it can work normally.

5. Ethernet M12 Interface

The Ethernet is equipped with "D" coded M12 connector with a metal shield housing, which is hole connector, and the definition as following:

6. CAN Interface Reference Circuit On Baseboard

The CAN interface on the TRDP module is the TTL level, which is the signal from the CAN controller. It needs to add the CAN transceiver to become CANH and CANL levels. So the recommended circuit is as follows:
