Adafruit IO is our IoT cloud service built from the ground up. Our basic free account is great, and lets you have plenty of feeds and dashboards. But maybe you want more than 'plenty'. Adabox 018 includes a one-year subscription pass to Adafruit IO Plus which upgrades your account's limits to:

  • 60 data points per minute
  • 60 days of data storage
  • Triggers every 5 seconds
  • Unlimited feeds

Also, when we add new features to Adafruit IO, we make sure they're always available to IO Plus subscribers first.

The Adafruit IO Plus card included in your Adabox should have a subscription code printed on the back (we've redacted it in this image).

First, if you do not have one already, sign up for a free Adafruit IO Account.

Log into your Adafruit IO account and navigate to

Under "Current Plan", click "Redeem Coupon or Pass".

Enter the secret code from the back of your Adafruit IO Plus card into the text box.

Click "Check Code".


Click "Redeem Pass" to apply the pass to your account.

After redeeming the pass, you will be taken back to the profile page. Underneath "Current Plan", your account should reflect that it's now an Adafruit IO Plus account!

If you are experiencing issues with redeeming your code, please visit and click "Contact Adafruit IO Support".
