Arduino Cloud is free for everybody

The number of Things you need depends on the complexity of the projects you plan to create. Each Thing allows you to create one connected object, which can be associated with one device. For example, connecting 5 smart lamps would require 5 Things, but using 3 sensors controlled by 1 Arduino board would only use 1 Thing.

You can switch to a better plan or update your billing information any time via My Plans page, available in your profile menu. These changes will take effect immediately.

You can also change billing frequency or downgrade to another plan. In this case, the changes will take effect at the end of your billing period.

Yes. When you request the Maker plan cancellation, the change will take effect at the end of the billing cycle (e.g. at the end of your billing month or year). Refunds are not allowed, even in case of account or subscription cancellation.

All projects are stored in the cloud, and will be saved as long as you have access to your personal account, regardless of the plan.

If you exceed the compilation time quota, you won't be able to compile the sketches until the quota is refilled next day. If you exceed sketch storage, you won't be able to edit your sketches until you have freed up some space. If you have exceeded the limits on Things or variables, you won't be able to use dashboards or connect your devices to the cloud until you have deleted the Things and variables that exceed your plan limits.

Yes! The Cloud Editor (online Arduino IDE) is always free to use. You can also try any Arduino Cloud plan free for 30 days—just add your credit card at signup. You won’t be charged if you cancel before the trial ends.

Absolutely! We do accept alternative payment methods like bank transfers and cheques. Simply select “Alternative Payment Methods” during the checkout process, and submit your request. Our sales team will then assist you with the next steps.

“Unlimited” features are designed for generous use within reasonable limits. To provide stability and performance for all users, we consider fair usage to include fewer than 256 variables per Thing, a maximum of 210 MB of sketch storage, and no more than 1,000 sketch files.
