Many things was happen with this project it recent months both on hardware and software side. Details could be found on project
home page or on the
GitHub. In the meantime I was successfully completed an experimental group buy for bare PCBs, TFT display and customized metal enclosure. That encourage me to start thinking about another group buy but this time for assembled modules and all other parts. But PCBA service makes sense only for larger quantity that means more people needs to be involved and I decide to run new group buy as a crowdfunding campaign.
The campaign will be conducted on the
CrowdSupply and I'd like to hear your opinions about pledge levels. First please note that I'm not going to offer a completed solution. The reason for that is CE/FCC certification that is very costly and for 100 units that is campaign goal it could make a whole calculation completely unattractive.
Again, this is a group buy,
not a new product production kick start, because it's not a profit driven (I have another source of money for living). Therefore prices of all pledges will be set to cover without loss the cost of manufacturing, packaging, transportation and campaign fulfillment cost, crowdfunding platform (12%) and payment gateway fees (2.9% + $0.30).
I was thinking about the following pledge levels (the final number and contents will be set in accordance with interested parties wishes):
- Set of bare PCBs only (4 of them, 2 layer)
- As above + metal enclosure (with other metal parts such as TFT display support, AC/DC modules support, channel's heatsinks)
- Set of assembled PCBs only
- As above + metal enclosure set + wire harness
- As above + TFT display + AC/DC modules (2 of them)
- As above + Arduino Due
The latest one include all what is needed to assembly a fully functional unit that can be ready to run after firmware is
uploaded. In essence you'll need a screwdriver for that operation and PC with Arduino IDE for uploading. Of course, you also need multimeter to calibrate it using built-in calibration wizard (see
video).
Thanks in advance for your valuable inputs.
