Built for Backers

Good news folks. We are almost ready to ship HealthyPi v4. All orders should be on their way to Crowd Supply within a few days, after which they will be sent to backers as quickly as possible.

As soon as the campaign ended, we shifted our focus to manufacturing and shipping. Electronics manufacturing being an inherently complex process, it’s difficult to foresee and plan for all contingencies that might arise as a project goes from design to production.

While waiting for the arrival of components that had been delayed due availability issues, we kept ourselves busy adding features, carrying out additional tests, and finalizing the design of our own simple, accurate, Qwiic-connected temperature sensor. With all crowdfunding and pre-order HealthyPi v4 units successfully assembled, we are now in the final testing phase.

We have added several additional features to the HealthyPi v4 firmware – and to the mobile application – that make health-related data both easier to measure and easier to read. We are in the process of making our source code and design files available on the ProtoCentral Github repository, and our online documentation is nearing completion. By the time you receive your HealthyPi v4, it will be ready and waiting to help you configure and use your new remote monintoring system.

Despite a few teething issues, HealthyPi v4 is now compatible with Raspberry Pi 4 single-board computers (SBCs), one of which is now included as part of our Complete Kit. We also tracked down a new case that has room for your HealthyPi v4 HAT and a Raspberry Pi to drive it.

Our team is working hard to ship everything on time, and we’ll keep you posted as more news comes in. Only the shipment to Crowd Supply is pending now! Thank you all for your patience and support!

Please remember, if you need to change your shipping address for any reason, you can do so through your Crowd Supply account.

To all our wonderful backers, we thank you wholeheartedly for your support. We wish you a Merry Christmas, a Happy New Year, and Happy Holidays. Thank you for being such an important part of what we do.
