# T1ADAPT Ethernet Adapter ## What is this board? The RDDRONE-T1ADAPT media converter translates between automotive 2-wire Ethernet (100BASE-T1) to Fast Ethernet (100BASE-TX). Automotive IEEE 100BASE-T1 compliant, with 100Mbit/s transmit and receive capability up to at least 15m of unshielded twisted pair (UTP) cable. Based on the TJA1101B 100BASE-T1 PHY and the LPC812 microcontroller Arm® M0+ MCU family, this plug and play tool is well suited for the evaluation and debugging of 100BASE-T1 Ethernet networks in various applications like Automotive, Industrial and IoT segments. Further, it can be used to develop distributed architectures where robotics nodes are connected over robust and reliable 100BASE-T1 Ethernet interfaces. ## List of Technologies & Specifications **Microcontroller (MCU)** - LPC812: Cortex®-M0+ Core low-cost MCU​ **Transceivers** - TJA1101B: Automotive IEEE 100BASE-T1 compliant, 100Mbit/s transmit and receive capability up to at least 15m of unshielded twisted pair (UTP) cable #### T1ADAPT Features: * Plug and play operation * Translation between 100BASE-T1 and 100BASE-TX Ethernet * DroneCode JST-GH connector or Pin header * LED status indicators * Supports simple connector schemes * Smaller size by not requiring RJ45 magnetics * Lightweight single pair wiring saves cost and weight **Interfaces** - Fast Ethernet RJ45, Two wire Ethernet 100BASE-T1, “DCD-LZ” SWD UART **Power** - 5V, Either via micro-USB or JST-GH Power connector​ **Software** - In this software solution for RDDRONE-T1ADAPT, the LPC812 to configures the two back to back PHYs over MDIO and drives status LEDs for the T1 PHY and manages network initiator/receiver mode switching. \*Source files available on request​ ## Links * NXP link to the product webpage: {% embed url="" %} * Design Files link: {% embed url="" %} * GitBook link: {% embed url="" %}
