Three new plug-and-play modules address common I²C limitations, extend communication distances and simplify motor control for Arduino-based embedded designs.
Arduino has expanded its Modulino ecosystem with three new plug-and-play modules designed to simplify hardware development and remove common obstacles encountered as embedded projects become more complex. The latest additions increase the Modulino family to 15 modules that can be mixed and matched using Qwiic connectors and daisy-chain wiring.
The new modules target three common challenges in embedded design. A hub module eliminates I²C address conflicts by providing eight independent I²C channels, each with its own isolated address space. This allows multiple devices with identical fixed addresses to operate together without requiring hardware redesigns or software workarounds.
A second module extends I²C communication over cable lengths of up to around 30 metres when operating at 100kHz. The hardware-only solution requires no additional software libraries or code modifications, making it suitable for distributed sensing and larger installations where conventional I²C connections become unreliable.
The third module is aimed at robotics and automation applications, integrating control for either two DC motors or a single stepper motor. By placing motor control electronics closer to the mechanism, the design reduces wiring complexity while enabling speed, direction and positioning control.
Like the rest of the Modulino range, the new modules connect through Qwiic cables, support daisy-chaining and are backed by dedicated libraries for both the Arduino programming language and MicroPython. Standardised module dimensions and breakout pins also provide scope for further customisation.
The modules are compatible with several Arduino development boards, including the UNO Q, Nano Matter, UNO R4 WiFi and Nano families, providing developers with a straightforward way to expand embedded systems without redesigning existing hardware.
