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.

M5 Stack Battery Module for ESP32 Core Development Kit Would you like to make a demo or prototype that requires long battery life? Perhaps using the battery in the M5GO base and the Basic base is not enough for you.Here comes the BATTERY which is a handy M5modules to upgrade your Lipo battery life. Since the Lipo batteries can work in parallel, you can stack multiple batteries to maximize your power endurance.CAUTION: The safety of the Lipo battery is affected by many conditions. Overcharge, over-discharge, over-temperature, short circuit, crush, and nail penetration may all result in a catastrophic failure, including the pouch rupturing, the electrolyte leaking, and fire. Although every battery we offer have accompanied by a protection circuit board, using Lipo battery in your product still needs to be treated with cautionOnce the BATTERY is stacked underneath the M5 controller, the battery positive pole is connected to the VBAT pin at IP5306 BATTERY: The Battery extension module is a 700mAh battery ADD-ON. Package Includes: 1x M5 Stack BATTERY Module Specification: Dimension 54 x 54 x 14mm Weight 36gm

M5 Stack BUS Module BUS allows you to add your own custom circuit design to the universal prototype perboard so it could interact with the M5Core via M-BUS. Just like other M5modules, BUS can connect with other layers through M-BUS, while in this module, we've extended the M_BUS pin to pin to the other side of the board. You might need to cut off the fence on the side to be able to expose the pins. We've included a 2*15 90 degrees pin set in the package. Also check Guide Rail for M5 Base. It features a spring-type buckle structure and multiple M3 screw holes for flexible installation Package Includes: 1x M5 Stack BUS Module Specifications: Dimensions 54 x 54 x 13mm Weight 23gm

M5 Stack Catch Unit (SG92R) The catch is a gripper that uses an SG92R servo as a power source. The servo uses a PWM signal to drive the gripper gear to rotate and control the gripper for clamping and releasing operations. The structure adopts a design compatible with Lego 8mm round holes. You can combine it with other Lego components to build creative control structures, such as robotic arms, gripper carts, etc. Note: Because the opening and closing angle of the gripper is 90°, please control the rotation angle of the driving servo to 0-45° (PWM: freq: 50Hz, 0°-45°(pulse:0.5ms-1ms) to prevent blocking rotation. The steering gear burned out. Applications: Robot gripper Steering gear manipulator gripper Package Includes: 1x Catch Unit(Built-in Servo-SG92R)1x HY2.0-4 adapter1x RoverC.Pro Connector Specifications: Servo model SG92R Drive signal PWM: freq: 50Hz, 0°-45°(pulse:0.5ms-1ms) Working frequency 50Hz Clamping jaw opening and closing angle 90° Input voltage range 4.2-6V Work dead zone 10us Output torque 2.5kg/cm at 4.8V Output speed 0.1sec/60° at 4.8V Working temperature 0°C to 55°C Dimensions 72 x 56 x 37 mm Weight 50gm

M5 Stack Color Sensor RGB Unit (TCS3472) COLOR is a color recognition unit integrated with the TCS3472 chipset. As the name says, COLOR is able to detect color value and return RGB data as a response.Identify color principle: The TCS3472 chipset is integrated with a 3*4 array of filtered photodiodes and 16-bit analog-to-digital embedded converters. Out of the 12 photodiodes, 3 have red filters, 3 have green filters, 3 have blue filters and 3 have no filter (clear), which gives a total range of RGBA (RGB + Transparency) When detecting the color of an object the TCS3472 returns data from four channels: red(R), green(G), blue(B) and clear(C)(non-filtered). The response from the red, green, and blue channels (RGB) can be used to determine a particular source’s chromaticity coordinates (x, y). Applications: Product Color Verification Color tracking robot Package Includes: 1x COLOR Unit1x Grove Cable Specifications: IC TCS3472 Workingtemperaturerange -40°C~85°C Communication protocol I2C：0x29 Dimensions 32.2 x 24.2 x 8.2mm Weight 17gm

M5 Stack COMMU Module Extend RS485/TTL CAN/I2C Port COMMU is a Muti-Communication-Interface-Converter. Integrated with 2I2C, 1TTL, 1CAN, 1RS485. Apparently, COMMU has packed with most of the series communications. Default connection: TTL - UART0, RS485 - UART2. Since the ESP32 pin map is allowed for re-assign, you can re-assign or re-mapping the TTL or RS485 interface to other pins. Be careful about TTL Interface. It is a UART Interface actually by default. But you can switch it to connect with UART2 after changing those jumpers(J6, J7, J9, J10). Package Includes: 1x M5 Stack COMMU Module Specifications: Interface I2C x2, CAN x1, RS485 x1, TTL x1 CAN Controller MCP2515-1/SO RS485 transceiver SP3485EN-L/TR Dimension 54.2 x 54.2 x 13mm Weight 24gm

M5 Stack Earth Moisture Unit EARTH unit is a Soil Moisture Sensor for measuring the moisture in the soil and similar materials.The soil moisture sensor usage is pretty straight forward, the two large exposed pads function as probes for the sensor, together acting as a variable resistor.The higher moisture that is in the soil means the better the conductivity between the two so that the sensor will result in lower resistance, and a higher SIG out.You can read the moisture in the soil by using the ADC. Inside this Unit, we've added extra potentiometers to change the measurement range. Note: Electrode of the unit is not anti-corrosive, or waterproof, for POC purposes only. Please, do NOT put it in a humid environment for a long while. Package Includes: 1x EARTH unit1x GROVE Cable Specifications: Dimensions 64.4 x 24.1 x 8.1mm Weight 18gm
