+
+## Description
+
+**Base PoE** is an M5 Base that implements a W5500 Ethernet controller chip with PoE module, which provides Hardwired TCP/IP embedded Ethernet control to facilitate easier internet connection to embedded systems. W5500 integrates TCP/IP protocol stack, 10/100M Ethernet data link layer (MAC) and physical layer (PHY).This base supports RS485 / RS232 communication and can be used as an Ethernet to serial port server. It is specifically designed for industrial applications. PoE (Power over Ethernet) technology is supported. Through the built-in PoE module, power can be directly supplied to the base through PoE hub / switch without a separate power supply. It comes with a couple of HT3.96 connectors, metal rail and magnet discs for easy installation. The 6 pins of the HT3.96 connector are spare, you can wire them up with an RS485 or RS232 adapter board as you like.
+
+**The figure below shows the internals of the LAN base**
+
+If you need to add an RS485 or RS232 interface, make sure to solder the RS485 or RS232 board onto the main board pin correspondingly.

+## Description
+
+**M5CameraF** is a development board for image recognition. It features an ESP32(4M Flash + 520K RAM) chip and 2-Megapixel carmera(OV2640).**M5CameraF** offers plenty of storage, with an extra 4 Mbyte PSRAM.  It also supports image transmission via Wi-Fi and debuging through USB Type-C port.
+
+
+The hardware comes preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image is size 600*800, since it's 2-Maga camera, you sure can optimize the software to output the maximum size of photos.
+
+what this software can do?
+- Power the board via USB type-C or GROVE
+- Use your phone to Wi-Fi scan an AP name start with 'm5stack-' and click to connect this AP.
+- Open up web browser on your phone and visit <mark>192.168.4.1</mark>
+- Then here comes the picture. Video is about 5-6 frames per senconds. not super fast.
+
+## Product Features

+
+>2. After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, click **"Burn"** to start burning. (**For M5StickC burning, please Set the baud rate to 750000 or 115200**)
+
+?>3. Currently EasyLoader is only suitable for Windows operating system, compatible with M5 system adopts ESP32 as the control core host. Before installing for M5Core, you need to install CP210X driver (you do not need to install with M5StickC as controller)[Click here to view the driver installation tutorial](en/related_documents/M5Burner#install-usb-driver)
