+# ATOM SWITCH Kit
+
+
SKU:K042
+
+
+
+## Description
+
+**ATOM SWITCH** is a bi-directional control programable switch for the M5ATOM. It can be connected to bi-directional AC / DC circuits for simultaneous on-off control. The on-board relay can support up to 250V / 16A AC or 5V / 1A DC output. Built in step-down module can provide 5V / 1A DC power supply. In order to ensure safe use, its DC circuit has a built-in self recovery fuse (250V / 1A), which can effectively disconnect the circuit in case of over current or short circuit. In order to facilitate the use of users in industrial scenarios, an SP485EE level-conversion IC is built in. There are also a set of RS485 interfaces provided for the user to connect RS485 equipment. In addition, a set of PH2.0 interfaces is also provided for connecting I2C peripheral equipment or general I/O equipment. With the Bluetooth and WiFi functions of M5ATOM, you can easily setup a remote control switch. If you have multiple M5ATOM HUB SWITCH modules, you can set them up in parallel through the RS485 interface.

+>EasyLoader is a concise and fast program writer, which has a built-in case program related to the product. It can be burned to the main control by simple steps to perform a series of function verification. Please install the corresponding driver according to the device type. M5Core host [Please click here to view the CP210X driver installation tutorial](en/arduino/arduino_development), M5StickC/V/T/ATOM series can be used without driver)
