Crowtail – I2C Hub 2.0 expands the I2C bus with three additional ports, enabling the simultaneous connection of multiple devices in the Crowtail system. Useful in projects with a larger number of I2C modules.
The Crowtail – I2C Hub 2.0 module enables the expansion of the I2C bus in systems compatible with Crowtail. Equipped with four 4-pin I2C connectors, it allows the simultaneous connection of up to three additional I2C devices using a single I2C port on the base board. It is useful in projects where the number of available I2C ports is limited. It enables the simultaneous operation of multiple devices thanks to separate I2C addresses. The simple design and quick connection support fast prototyping.
8-channel analog acquisition module with default current measurement mode (0–20 mA), designed for industrial applications requiring stable and precise data acquisition. Compatible with current sensors, it supports RS485 communication and the Modbus RTU standard, allowing easy integration with SCADA systems and PLC controllers. Galvanic isolation and noise immunity make it suitable for environments with high EMC requirements. Ideal for industrial process monitoring, environmental parameter measurement, and building automation.
