They're on Their Way!

by Jon Luke

Yes, the wait is very nearly over. We are delighted to announce that we shipped our first production batch to Crowd Supply last Friday, and they are all packaged up and ready for final distribution to our backers. Thank you all for your support. We literally could not have done this without you!

And remember, if you’d like an EMIT of your own, it’s not too late to order one. Crowd Supply will soon have plenty of stock for post-campaign sales, so you can pre-order EMIT from our campaign page.

Please Update Your Shipping Address!

Orders will begin shipping next week, so please take some time to check your Crowd Supply account and make sure that your shipping address is up-to-date. By doing so, you will help Crowd Supply avoid delays. Once they have sent your order details to their warehouse team for processing, it may be impossible for them to re-route your shipment. If you have fulfillment-related questions or concerns, please contact Crowd Supply Support.

Arduino/C++ Developer Guide

One of the aims of this project was to make EMIT—and IoT in general—as accessible as possible. To that end, we recently released our Firmware Developer Guide for Arduino/C++. So now, when it comes to firmware development, you can choose between MicroPython and Arduino/C++. Please visit our developer wiki for more information and developer resources.

EMIT Support Forum

As of today, we’ve also launched a dedicated support forum to help provide as much direct support as possible. You an find it at https://forum.controlbits.com. At the moment, it’s mostly "tumbleweeds and good intentions," but we really hope you’ll sign up there and help us build a thriving community of IoT developers.

See you there soon. And stay safe!
