## OpenThread Border Router
[](https://www.threadgroup.org/What-is-Thread#certifiedproducts)
OpenThread Border Router (OTBR) has been certified as a Thread Certified Component on the
[Raspberry Pi 3B](https://openthread.io/guides/border-router/raspberry-pi-3b) with a
[Nordic Semiconductor nRF52840](https://openthread.io/platforms/nrf52840) NCP.
OTBR was certified using the following releases and commits:
| Repository | Release / Commit |
|---|---|
| OpenThread | [`thread-reference-20180926`](https://github.com/openthread/openthread/releases/tag/thread-reference-20180926) |
| wpantund | [commit `8c189c6`](https://github.com/openthread/wpantund/commit/8c189c69b4431c6dd3413fcd423ffe0b4c67960c) |
| OpenThread Border Router | [`thread-br-certified-20180819`](https://github.com/openthread/ot-br-posix/releases/tag/thread-br-certified-20180819) |
[OTBR Thread Certificate](https://openthread.io/static/certification/11A023_2018_10_31.pdf) [OTBR Thread Certification Release](https://github.com/openthread/ot-br-posix/releases)

## Certify with OpenThread
Other platforms running OpenThread, including NCP designs, can be certified as
Thread Certified Components. OpenThread can also be used for a product
certification, which carries the "Built on Thread" badge.
For more information about the difference between Thread and OpenThread as it
relates to certification, see the [Thread Group FAQ](http://threadgroup.org/About#faq).
> [!NOTE]
> **Note:** To certify, you must have [Implementer, Contributor, or Sponsor
> Membership](http://threadgroup.org/thread-group#Membershipbenefits) in the Thread Group.
### Why certify?
Certification indicates to customers that your product is fully Thread
compliant, and that it works with other Thread products. Product certification
is required to ship a product based on OpenThread, and to claim that a product
supports Thread.
Certifying a product running OpenThread provides an added benefit, given
that OpenThread itself is a Thread Certified Component. Certification time and
costs are generally reduced, as the Thread Group's test houses are already
familiar with OpenThread as a reference stack.
### Testing
Certification testing is done with the
[GRL Thread Test Harness](http://graniteriverlabs.com/thread/), available for
download to Thread member companies. To increase the likelihood of a successful
Thread certification using OpenThread, we recommend running and passing all
certification tests in a local setup prior to submission to the Thread Group.
