M5 Stack BUS Module

M5 Stack SERVO2 Module 16 Channels - 13.2 (PCS9685) SERVO 2 is an updated servo driver module in the M5Stack stackable module series. It uses a PCA9685 16 channel PWM controller to control 16 channel servos at the same time. The power input is 6-12V DC and two SY8368AQQC chips are used for voltage reduction. The maximum total power output of a dual-channel is 35W (5V / 3.5A * 2), and the maximum output power of a single-channel is 25W (5V / 5A). When the battery base is used for the power supply, the maximum output power is 5V / 2A. The module communicates with the host directly through I2C (the default address is 0x40) however the I2C address can be changed(0x40 - 0x47) through the dial switch. This also means that multiple Servo 2 modules can be stacked and used simultaneously. There is a power switch on the board to control the power supply of Servo 2. Note: The module must use the external power supply of the DC interface when driving the servo. When using the AXP192 power management chip's main control (such as CORE2), the M-BUS power mode needs to be configured as an input when the program is initialized. Applications: Humanoid robot Bionic multi-joint robot 3-axis steering gear pan tilt

M5 Stack PROTO Module with Extension & Bus Socket PROTO is a pure universal prototype perboard. You can have the total freedom to make your own project as you want it, with prototyping perboards that allow laying out the customized circuit to interact with the M5 core via M-BUS.

M5Stack COM.NB-IoT Module (SIM7020G) with antenna COM. NB-IoT is a stackable multi-band NB-IoT wireless communication module with a built-in SIM7020G communication module. The module supports PSM and eDRX low power consumption modes. The COM.NB-IoT module has a wide coverage signal. Compared to GSM, NB-IoT has a strong gain, which also enables the product to have wireless communication capabilities in locations such as basements. The module has a DC power input and can provide a 5V-12V power supply through an external power supply. In order to facilitate the user to configure the pin, the DIP switch is used to set the pin. The SIM7020G module is the optimal solution for low latency, low power consumption, and low throughput applications. It is very suitable for IoT applications such as metering, remote control, asset tracking, remote monitoring, telemedicine, and ride-sharing. Note: The module base has a DC power input interface. Please strictly follow the input range (5-12V) to prevent damage to the module when using this interface to connect to the power supply. The internal power DIP switch can adjust the voltage level of the internal terminal VIN to adapt to different modules. Applications: Smart meter Smart parking Municipal management

M5Stack Goplus2 DC Motor and Servo Driver Module (STM32F0) M5Stack GoPlus2 is a stackable multi-functional motor and servo control module. The master control integrates the STM32F030C8T6 chipset. The module is equipped with a 2-way DC motor drive interface and a 4-way servo drive interface. Three PORT-B interfaces(Analog Input, Digital Output, Digital Input) can be expanded. Built-in 500mAh battery and support infrared (IR) transmission and reception. In order to meet the requirements of a multi-channel interface power supply at the same time, a DC power interface is provided for external power supply, the battery can be charged through the M5Core with USB-C. Communication protocol: I2C(0x38) Applications: Actuator / motor driver Acquisition and control of multiple input and output signals Infrared controller DIY Toy base

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).

M5Stack LoRa Module for ESP32 DIY Development Kit (433MHz) LoRa (433MHz) is a LoRa communication module in the M5Stack stack module series (working frequency is 433MHz). Certain expansion space is reserved on the module, which defeats you for a more functional design. For wireless communication or projects with more customized elements, the M5Stack LoRa module (433MHz) will be a suitable choice. Applications: Automatic meter reading Home building automation Remote irrigation system
