Module with 8-digit 7-segment LED display. The board is equipped with a 74HC595 driver and communicates via a digital interface

Energy-saving 24 GHz sensor LD2410S based on FMCW technology and the Doppler effect, designed to detect human presence and micro-movements in real time. Thanks to the built-in AI algorithm and a range of up to 8 meters and a wide detection angle (±60°), it is perfect for building automation, smart lighting and IoT devices. It supports UART and GPIO interfaces, offers very low power consumption (from 0.04 mA in standby mode) and allows configuration through intuitive tools, making it ideal for integration in modern projects.

BLE Beacon, which emits Bluetooth Low Energy signals, enabling discovery by Bluetooth devices such as smartphones or ESP32 without the need for pairing. With a built-in I2C interface and an 11-bit ADC, it allows data collection from various sensors, and its low power consumption (650nA in sleep mode) ensures long-lasting operation on a single battery, ideal for applications requiring mobility and long range.
