In our opinion, the only thing the Raspberry Pi 4, Pi 3, and Pi 2 are truly lacking is an I2C port. (Of course you may have guessed by looking at our product offerings that we are, admittedly, a little biased. No worries.)
The INPI2 is a non-invasive I2C adapter complete with level shifter providing you with a +5V I2C port for use with ANY of our I2C devices. The I2C port points inward minimizing the footprint of the expansion. The INPI2 does NOT consume the 40-pin expansion port, as it is equipped with a pass-through connector, freeing the 40-pin connector for other purposes, making it a truly non-invasive design.
This is a nodeLynk Master adapter. nodeLynk Master adapters speak to a chain of nodeLynk devices using I2C communications.
Chain expansion devices using nodeLynk. Connect a wide variety of accessories to expand the capabilities of a nodeLynk compatible controller. Use nodeLynk to add Relay Controllers, Sensors, PWM Drivers, Displays, and a wide variety of 4-20mA, 0-10V ADCs and DACs, as well as a wide array of TTL & Isolated GPIO devices. All nodeLynk devices use I2C communications to chain devices together. nodeLynk is an easy way to expand functionality without soldering. nodeLynk allows expansion in seconds so you can focus on your software and firmware development.
This adapter provides a general-purpose I2C port, compatible with our complete line of I2C devices. Control relays, monitor current, read just about any kind of sensor you can imagine.
