Description
The M5Stack K132-Adv Cardputer is a highly integrated, portable development board designed for engineers and makers requiring a compact, feature-rich platform for IoT and embedded systems. Based on the Espressif ESP32-S3FN8 chip, it combines a powerful dual-core processor with 2.4GHz Wi-Fi and Bluetooth 5.0 Low Energy, providing the core connectivity for smart home automation, industrial control, and wireless sensor networks.
Beyond its processing core, the Cardputer is distinguished by its comprehensive human-machine interface (HMI). It integrates a full 56-key keyboard and a 1.14-inch color LCD display for direct input and data visualization, eliminating the need for external peripherals during field testing. The board further expands its utility with an onboard audio subsystem for voice wake-up and playback, an IR emitter for device control, and multiple expansion ports for connecting a wide array of Grove-compatible sensors and modules via I2C, UART, or GPIO.
Power management is handled by an internal 1750mAh lithium-polymer battery, supported by dedicated charging and regulation circuits that enable extended cordless operation. The device’s ultra-low-power sleep modes, with currents as low as 0.26µA, make it suitable for battery-powered edge applications. Its unique card-sized form factor, magnetic base, and Lego-compatible hole pattern offer unparalleled flexibility for prototyping and deployment in educational, industrial, and DIY environments.
