In stock (10)


The Tentacle shield is COMPATIBLE with all 5V-tolerant Arduinos (Uno, Mega, Yun, & many more). The Tentacle shield is not compatible with Arduinos that can’t tolerate 5V on their I/O pins (Zero, Due, etc). If you need 3.3V compatibility, the Tentacle Mini is for you.

  • stack 2 shields to get 8 isolated sensor channels
  • I2C and UART compatible

On-board Serial Multiplexer

With the on-board serial multiplexer you can use up to 4 circuits in UART mode per shield – using just 4 pins of your Arduino!

Stack two tentacles to get 8 serial channels.

Extra long pin headers to stack multiple tentacle (or other) shields on your Arduino hassle-free. On-Board reset-button to reset your Arduino without removing shields. Includes a mounting kit with plastic standoffs.


• No wiring, no bread boards
• No soldering necessary, comes fully assembled
• Built in electrical isolation means that sensors won’t
interfere with each other, and removes outside electrical
noise that can interfere with readings.
• Stackable design lets you control up to 8 sensors at once
• Integrated serial multiplexer
• Works in both UART mode, or I2C mode
 5V compliant Arduino only!
• Tentacle Shield does not come with EZO™ class devices.
