K012-B

LAN Module with W5500 SKU: K012-B Although M5 core is ESP32-based, having Wi-Fi and Bluetooth intergrated, it doesn't stop you enable the Ethernet function. This LAN is a M5 Base that having a W5500 chip, which is a Hardwired TCP/IP embedded Ethernet controller that provides easier Internet connection to embedded systems. This Base is speciffically design for industrial application scenarioes, comes with couple of HT3.96 connectors, 485 metal rail and magnet discs for easy installation and fixation. Product Features • • • • Input Supply Voltage: 9-24V HT3.96 port for supporting RS485 Support RS485 communication Easy to fixed on the wall Kit includes • • • • • • • • • • • • 1x LAN Base 1x TTL-to-RS485 adapter board 1x pin header 20pin 1x metal rails and magnet discs 3x HT3.96 terminal 2x 3pin 1x 4pin 10x cold crimp terminal 3x Allen wrench - 1x 1.5mm - 1x 2mm - 1x 2.5mm 2x hexagon socket head cap screws M3x28 4x hexagon socket tapping screw KA2x4 1x countersunk head screw M3x8 Application • M5Core + LAN implemented a conveyor controller • PC transmits video to Core via cable Datasheet - W5500 The 6 pin of HT3.96 connector are dangling, you can wired them up with the M-BUS and other circult as you like. The figure below shows the inner of LAN If you need to add RS485 interface, soldering the RS485 board onto the mian board pin correspondingly. TTL-to-RS485 adapter board and LAN base The figure below tells you how the TTL-to-RS485 adapter board connected onto LAN backplane The serial port pins on the RS485 board will be connected to the GPIO16 and GPIO17 of the LAN backplane. PinMap W5500 W5500 ESP32 Chip MOSI GPIO23 MISO GPIO19 CLK GPIO18 CS GPIO26 RST GPIO13 INTn GPIO34 M-Bus Schematic https://m5stack.com/collections/m5-base/products/lan-module?variant=16804778803290/12-99-19
