Almost There!

It's been a hell of a journey. In the past week, we've been working extra hard to ensure fulfillment time and schedule as planned. The 200 Eduponics mini PCBA arrived at us yesterday and now we are left to test each one of them using a custom QA script we've developed in order to ensure the proper functionality of each device.

Extension Board Gets an Update!

Over the past two weeks, we've noticed that a lot of backers have been requesting more than a single Eduponics Mini Extension Board. Which makes sense, given that we described how one Eduponics Mini ESP32 Dev Board can support up to four extension boards. Until recently, however, a setup like that would have required additional soldering to configure the resistors that control the I²C addresses. And that, in turn, could inconvenience our users and perhaps even result in damaged boards—neither of which we want. Our solution? DIP Switches! This update covers that and other extension-board upgrades. Read the full update.

Tracking Down Components & Getting Ready for PCBA

The support and feedback we've received so far have been incredible. Without our loyal backers, none of this would have been possible, so thank you! In this update, we talk a little about the feedback we've been receiving, describe some of the component-availability issues we've managed to overcome, and tease a surprise feature of our Expansion Board.
