The piwheels project wouldn’t be possible without considerable support from Mythic Beasts, who provide storage, bandwidth and cloud Pis. The Pi platform is so straightforward, it’s been a pleasure to use, allowing us to scale up builder Pis with ease. We highly recommend using this (very affordable) service for real Pi testing for your projects.
