Lean process and adjusted goal

After the update last week, I have more news, this a bit more important than the last. My original campaign goal was calculated with the first revision design, under the assumption that 100% of the assembly would be done by PCBWay. As anyone familiar with manufacturing knows, there is a certain minimum order quantity needed to get an acceptable price.

Not knowing what to expect of a campaign, that was my initial direction. However, with the current status and number of units needed, I can assemble the biggest (read: highest cost) part of the design myself, and avoid buying the total number needed for the batch in excess of what’s ordered, making my goal significantly lower.

The plan is to have the PCB’s manufactured and populated with all components except the ESP32-WROVER-B, and to add that component myself before doing the already planned program and test. This way I can avoid some freight costs, some risk in things being lost/delayed in shipping, and I can keep a lower total value of inventory on hand (buzzword: lean manufacturing, just in time).

And so after some discussion with Crowd Supply, a new goal has been set. We’ve also extended the campaign deadline one week to allow backers time to process this goal change. I thank you all for your interest and support!

If any backers do not feel comfortable with this goal change, they can cancel their order before the end of the campaign and they will not be charged a thing. If you have any questions about this decision, feel free to reach out to us through to form below.
