Product description
This development board combines a powerful microcontroller with wireless communication in a compact design. With its dual-core processor and 240 MHz clock frequency, it provides sufficient processing capacity and memory for more complex projects. WiFi and Bluetooth enable wireless connections to networks, smartphones, or other devices without additional modules.
The 26 GPIO pins provide flexibility when connecting sensors, switches, and actuators. The I2C, SPI, and UART interfaces allow several components to operate simultaneously, such as a temperature sensor, motion detector, and LCD display on the same board. The integrated USB interface supplies power to the board and serves as a programming connection, making external programmers unnecessary.
Typical applications include connected measurement stations that send sensor readings to a home WiFi network, controls with remote access via smartphone, or IoT prototypes with data logger functionality. Home automation projects with local control of multiple devices can also be built with it. A real-time clock or additional sensors can be connected via I2C when needed.
Programming requires the usual development environment and a USB connection to the computer. Any USB power supply or a 5 V battery pack can be used as an external power source if additional power is required for higher loads than USB can provide. A level shifter is required when operating with other voltage levels or in systems with 3.3 V logic.
Safety information
The board is intended exclusively for building prototypes and for testing and development purposes and is not suitable for installation in the household electrical circuit. Work on or near electrical installations must be carried out by qualified electricians. Consult a qualified electrician before commissioning when connecting high-current actuators or operating with external voltages.
