+## Description
+
+**Base15** is a highly customizable bottom for industrial purpose. Similar to PLC Base but higher customized level.
+Package includes protoboard which allows you to add up your own circuit design. On the board, two Grove bonding pads are reserved. Another component comes with the package is an M type waterproof joint which can be assembled on the side and the bottom of the Base.
+'15' comes from the hight of the bottom which is 15 cm. and each side on the Base is movable, cuttable and can be customized into different Interface. With regards to the bottom side customization, we have offered plenty of structural components alternative and it is totally opensource. You can 3D print the parts and replace the side as you like.
+
+
+At the bottom side of the product, we have offered 2 different fitting ways: Din-Rail, Hunger.
+
+
+Of course, it is absolutely compatible with the stackable M5module and extendable M5Units.
+This base gives you an unlimited of combinations, it is powerful, flexible, and covered with an industrial-grade case. If you happen to work in an industrial field, We especially recommend this Base to you which will surely give you the best and the fastest way to resolve your requirement.

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.
-The 6 pin of HT3.96 connector are dangling, you can wired them up with the M-BUS and other circult as you like.

## Description
**PLC** is a Base specifically design for industrial application. DC Power in 9-24V.
-Does this PLC remind you of the 'PLC' in industrial controll short for 'Programmable Logic Controller'. This PLC base is not the typical 'PLC' used in programmable controller, but its does able to implement the most common controller in industrial field. Based on the current M5 development system, you can add as many Realys as you want, you can enable the TTL-RS485 communication, you can layout your customized circult on the protoboard. you also can make it an LoRa node by stacking a LoRa module etc. This base gives you unlimited number of combinations, it is powerful, flexiable, and covered with industrial-grade case. If you're happen to working in an industrial field, We especially recommend this PLC base to you which will surely give you the best and the most fast way to resolve your requirement.
