Capsule

SKU:K129

Description

Capsule is a multifunctional embedded development platform using Stamps3 as the core controller, integrating key functions such as sensors, power supply, storage, and control. It features a high-performance BMI270 IMU for precise motion tracking and attitude control, an SPM1423 microphone sensor for recording, voice recognition, and wake-up, and an infrared sensor for remote control. For power supply, the platform has a built-in 250mAh battery and supports external battery expansion to ensure long-term operation. In terms of data storage, the TF card slot expands storage capacity for data logging and media storage. The RTC8563 real-time clock module provides high-precision time and date information and supports timed wake-up for low-power functionality. Additionally, a buzzer provides audio feedback, while the Proto pin header offers extra expandability, allowing connection to custom sensors and expansion boards to meet various project needs. Structurally, it embeds 4 magnets and 2 M3 screws for attachment, increasing usage scenarios. This product is suitable for building IoT, embedded systems, sensor applications, and smart device data acquisition systems.

Power On/Off

Power On: Can be awakened by pressing the "WAKE" button and the RTC timed IRQ signal. After triggering the wake-up signal, the hold (G46) pin needs to be set to high (1) during program initialization to maintain power; otherwise, the device will return to sleep mode.
Power Off: When there is no external USB power supply, press the RST button to power off, or set HOLD (GPIO46)=0 during program execution to power off without USB external power.

Download Mode

To enter download mode, press the G0 button on StampS3 during power on.
