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

M5 Stack COMMU Module Extend RS485/TTL CAN/I2C Port COMMU is a Muti-Communication-Interface-Converter. Integrated with 2 I2C, 1 TTL, 1 CAN, 1 RS485. 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).

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.

M5 Stack PDM Microphone Unit (SPM1423) PDM mini Unit is a digital MEMS silicon-based microphone based on PDM (Pulse Density Modulation) signal. The microphone has a high signal-to-noise ratio, high sensitivity, low power consumption, anti-radio frequency interference, smooth frequency response, and other characteristics. It automatically switches the microphone state according to the clock frequency (power down/activate/sleep)and can be widely used for the audio data collection on wearable devices and smart digital devices. Applications: Spectrum Analyzer Recorder Noise meter

M5 Stack Mini Angle Unit with Potentiometer ANGLE is a rotary switch Unit that simply includes a 10K Ohm potentiometer inside. This unit can be used for Continuous signal rotatory control for applications such as volume, brightness, or motor speed. A potentiometer is a manually adjustable variable resistor with three terminals: Two terminals are connected to a resistive element, the third terminal is connected to an adjustable wiper. The position of the wiper determines the output voltage. The out voltage is captured and converted by AD on ESP32 on portB. In the M5 Stack product system, Normally the Grove color indicates the type of communications. Black: Single BUS (AD, DA, GPIO) Red: I2C Blue: Uart White: Others(depends)
