Yulo Connect

Yulo Connect extends the capability of the Koala Connect® to create a tiny yet powerful IoT platform.


Yulo Connect extends the functionality of the Koala Connect to create a tiny yet powerful IoT platform with modular sensors and a battery support board to enable compact battery powered projects. Yulo Connect has been designed to get your hardware/software prototype up and running quickly and smoothly with a variety of easily interchangeable sensor packages. Offering the same wireless connectivity choices as the Koala Connect, many Yulo Connect and BLE devices can be connected together to create a IoT sensor network. Get your IoT project up and running with reduced risk and start publishing sensor data to the cloud in minutes with the support of our MQTT demo application.




Yulo Connect sensor modules work on a I2C bus using standard header connectors to enable easy interchangeability. Its open design allows for easy integration with sensor boards of your own design or ours, we have many sensor boards available which covers most popular sensor types you may find in a embedded IoT product.
