1pcs LAN8720 Module Network Module Ethernet Transceiver RMII Interface Development Board For Arduino DIY

Semi-finishedproduct : No High-concerned chemical : none Electronic : No Model Number : LAN8720 DIY Supplies : Electrical Brand Name : Stlxy Origin : Mainland China Output Voltage : +1.6V~+3.6V

Main chip: LAN8720A Ethernet PHY physical layer transceiver chip Interface mode: RMII interface (excluding MAC controller, requiring the main controller to have its own MAC) Network port: HR911105A RJ45 built-in pulse transformer with link/activity indicator light Speed: 10Mbps/100Mbps adaptive, full duplex/half duplex adaptive Power supply voltage: 3.3V power supply, IO level 3.3V, 5V input strictly prohibited Working temperature: Industrial grade temperature range Applicable main controller: STM32F1/F4 series, some MCUs that support RMII MAC; Can be used in conjunction with Arduino expansion Output pins: all RMII signal pins, reset pin, power ground pin, convenient for soldering pins

LAN8720A Ethernet PHY physical‑layer transceiver chip. RMII interface, 10/100 Mbps auto‑negotiation, full‑duplex / half‑duplex adaptive. Integrated HR911105A RJ45 magnetics jack with link and activity LED indicators. 3.3V power supply, all IO 3.3V level, do not apply 5V signal. Note: This is PHY‑only module, MAC controller must be provided by host MCU. Widely used for STM32, embedded system, IoT wired network, Arduino DIY project. Notice: Host microcontroller must support RMII MAC function; 5V IO will damage chip.
