M5 Stack Mini 3A Relay Unit RELAY as it says is an M5Unit that implements Relay functions. Relay can be used as an electrically operated switch, uses an electromagnet to mechanically operate a switch, where it is necessary to control a large power load circuit by a separate low-power signal such as digital signal output from a microprocessor.The Relay support input voltage of up to 30V DC and 220V AC.There are 3 pins named: ON, OFF, COM. You can program to make COM connect to ON or OFF, just by high and low output of a digital GPIO. Applications: Remote control of high-power appliances, such as refrigerators, air conditioners, TVs, etc. Also check the M5 Stack Grove-T Connector, which comes in a package of 5 pieces. It is a T-shaped hub called CONNEXT-T, used for CONNEXT port expansion. Also check M5 Stack 1 to 3 HUB Unit. The HUB Unit is a device that allows you to connect more GROVE ports to your M5Stack device. This is useful if you want to use multiple sensors or other devices at the same time.  Package Includes: 1x RELAY Unit1x Grove Cable1x 3.96 socket Specifications: Dimensions 48 x 24 x 21mm Weight 26gm

M5 Stack 1 to 3 HUB Unit HUB is a unit that is used in order to expand the GROVE ports over the M5Stack device. For example, if we want sensors with different I2C addresses or output to 3 devices at the same time. (M5Stack device usually can output one device at a time to limited amount of grove ports)Note: HUB is just a hardware expander, if you are looking for a hardware and software (standard protocol) expander like I2C, Single-bus, please check PaHUB or PbHUB.If you are connecting two I2C slave devices onto HUB that share the same address, you will have a problem getting I2C data from both. The I2C addresses of the devices must be different, they can be changed manually by changing the resistor values. Also check M5 Stack Solid State Relay Unit(BT136S). The unit is a small, single-phase AC relay that can be controlled with a DC signal. It has built-in optocoupler isolation and overcurrent protection. Package Includes: 1x HUB Unit1x Grove Cable Specifications: Dimensions 32 x 24 x 12mm Weight 17gm

M5 Stack Grove-T Connector (5pcs) CONNEXT-T is a T-shaped hub. Is this remind you of the HUB unit? They are basically the same thing, just in different shapes. This is also used for CONNEXT port expansion.Note: CONNEXT-T is just a hardware expander, if you are looking for a hardware and software(standard protocol) expander like I2C, Single-bus, please check PaHUB or PbHUB. If you connected two I2C slave devices onto HUB that share the same address, you will have a problem getting I2C data from both. Also check the M5 Stack Mini 3A Relay Unit, It is described as an M5Unit implementing Relay functions, serving as an electrically operated switch. The Relay supports input voltage up to 30V DC and 220V AC. It has 3 pins named ON, OFF, and COM, allowing programming to connect COM to either ON or OFF using digital GPIO output. The applications include remote control of high-power appliances. Package Includes: 5 x Grove-T Connector

M5 Stack Solid State Relay Unit(BT136S) UNIT SSR Solid-state relays are different from traditional electromagnetic relays in that their switching life is much longer than that of electromagnetic relays. With integrated MOC3043M optocoupler isolation and zero-crossing detection, It supports input 3.3-5V DC control signal, and control output single-phase 220-250V AC power.UNIT SSR is controlled by power semiconductor devices, with microsecond on/off speed and built-in overcurrent protection. Extensively used in lighting control, CNC machine tools, etc., where frequent on/off lines and fast response are required. Note: 1. Please be careful when using high voltage AC loads, and do not operate with electricity.2. This relay is for AC loads only. Applications: Motor control Industrial and domestic lighting Heating and static switching Stage lighting Medical equipment, traffic signal lights Package Includes: 1x Unit SSR1x HY2.0-4P Cable Specifications: SCR Model BT136S Optocoupler Isolation Model MOC3043 Control Signal 3.3-5V DC On/Off Voltage 单相 AC: 220-250V Max. load current 2A Number of control channels 1 Overcurrent protection Fuse: 2A Operating Temperature -10 to +80°C Dimensions 54 x 54 x 16mm Weight 70gm
