FAQs
Can I connect multiple Modulino Latch Relay nodes to a single QWIIC connector?
Absolutely! You can connect several Modulino Latch Relay nodes to the same QWIIC bus. To do this, you'll need to assign a unique I²C address to each Modulino node. The Modulino library includes an example sketch called AddressChanger that simplifies this process.
Is a QWIIC cable included with the Modulino node?
Yes, each Modulino node is packaged with a 5 cm QWIIC cable, so you can get started right away.
Are the Modulino nodes compatible with other QWIIC devices?
Yes, the Modulino nodes are designed to be compatible with other devices that adhere to the QWIIC standard and operate at 3.3V. Always double-check the voltage compatibility of any QWIIC devices you intend to use together.
What voltage do the Modulino nodes operate at?
The Modulino nodes are designed to operate at 3.3V. Ensure that your microcontroller or other QWIIC devices provide this voltage level to avoid damage.
Do I need any special libraries to use the Modulino nodes with Arduino?
Yes, you'll need to install the Modulino library either for Arduino language or Micropython, which provides functions and examples to easily interact with the nodes.
