M5Capsule is a embedded development board powered by Stamps3. It combines essential functionalities such as sensors, power management, storage, and control, making it suitable for building IoT, embedded systems, sensor applications, and rapid prototyping and validation of smart device data acquisition systems. With its high-performance BMI270 IMU, enables precise motion and attitude control. It also features the SPM1423 microphone sensor, supporting recording, sound recognition, and wake-up functions. The integrated infrared sensor adds versatility for remote control, signal recognition, and smart home applications. The built-in TF card slot allows for expandable storage capacity, facilitating data logging and media storage. Additionally, the built-in buzzer provides audio feedback, enhancing user interaction. M5Capsule is designed with low power consumption in mind, featuring a power-efficient design with a standby leakage current as low as 35uA. It comes with a built-in 250mAh battery and supports external battery expansion for extended operation. The device also includes the RTC8563 real-time clock module, providing high-precision time and date information and supporting timed wake-up functionality. Power on and off Power On: The device can be awakened and powered on either by pressing the "WAKE" button or by the -triggered signal. After the wake-up signal is triggered, during program initialization, it is necessary to set the "hold" (GPIO46) pin to a high level (1) to maintain power. Otherwise, the device return to sleep mode. Power Off: When not externally powered via USB, the device can be turned off by pressing the button. Alternatively, during program execution, setting HOLD (GPIO46) to 0 achieve a power cutoff shutdown. Note:due to different production batches, the printing screen printing/appearance is different, which does not affect the use.
