TJA110x 2-Wire Ethernet

NXP's TJA1101 is an Ethernet PHY that provides a two-wire 100BaseT1 Ethernet interface. The Ethernet MAC side of this interface is not unusual, and the traffic on the line is "regular Ethernet"

NXP's Flight controller for Mobile Robotics - RDDRONE-FMUK66 includes a 2-wire Ethernet interface on board. In order to connect this with the 8MMNavQ this media converter can be used. The RDDRONE-T1ADAPT is also useful when connecting to other experimental modules such as V2X or an Automotive 5/10 port switch.

Connecting the RDDRONE-T1ADAPT

On RDDRONE-T1ADAPT power is supplied via a 3 pin JST-GH connector. There is a matching 3 pin JST-GH connector on the 8MMNavQ. A simple 1:1 cable is used. Optionally a USB-C cable can be used to provide power (only) connection. A 2 pin JST-GH connector is used for connecting Ethernet between this board and another - such as the RDDRONE-FMUK66. A simple 1:1 cable is used.

There are also locations marked on the bottom side of the board for soldering in wires for both power and 2-wire Ethernet

RDDDRONE-T1ADAPT Software

There is a small NXP LPC processor on board to configure the back to back PHYs and manage setup and LEDs. This board comes pre-programmed and there is no user software required. Contact hovergames@nxp.com or your local NXP representative if there is a specific need to access the software.

This LTE Cat M1 modem is a small form factor module for development that includes the PX4 type connectors suitable for connection with the NavQ.

Cellular IoT solutions are new standards defined by the 3GPP Group to answer requirements such as low power, long range and low data rate usage. Two standards currently exist - LTE Cat.M1 is one of the current standards and is intended for low bandwidth intermittent use, as expected for an IOT-type device.

Cat M1 can deliver secure, world-wide coverage by using the same base stations, public networks and power supplies as mobile phones.

It is important to recognize that Cat M1 is not the same as 4G LTE data bandwidth you have come to expect on your cell phone data plan. This is not suitable for streaming video, instead it would be intended more for intermittent low bandwidth telemetry or sensor data.

Generally speaking LTE Cat M1 modems are designed to support these features:

• High Security, Encrypted communication and FOTA

• Low consumption capable of 10+ years of battery life

• Wide coverage using existing smartphone networks

For development, use on a rover or ground station there is a 5" LCD panel that can attach to the NavQ MIPI DSI output.
