I would be interested in at least 2 of each, if 22mm came along I would not be unhappy. If you decide to do the fet tail boards, 4 or 5 of them as well.
Been thinking about the tailswitch and will likely get a bunch of the boards made, and perhaps a small lot of the pogo programmer boards too, but I will leave it up to everyone to build them. They are not too difficult to assemble and is a good way for those to get used to SMD work
Since there is alot of interest in the 20mm version, I may as well ask the manufacturer how much more it would cost if they can do half the batch in 20mm, since its the same components, it wont be too difficult for them to do both runs together, but will still be seperate cost for another pcb design, stencils, etc so not too sure what saving there would be at this stage.
Changing R13, the 0402 resistor to 120k should give you 9v operation.
Sense resistor R1 would probably need to be changed also to some where in the 15mohm range.
.
Everything will be shipped with default firmware. I would like to see some devs in the community play around with it and write some of their own if there are people with that skill with arduino in here.
There is quite alot of potential with firmware.
And an update on pricing.
Ive got my initial quote in and component costs are just shy of $20 per board, so we are looking at $1962 total component cost for 100 boards and fabrication costs of the PCB and assembly.
We are not going to be much below $30 per board if at all by the time I get charged with import tax at my end.
Would like to feel out how much everybody is prepared to pay for a driver, and would need to fill in most of the orders before we go ahead.
If I cant get enough orders in, I may have to opt for a lower amount produced perhaps 50 boards, but this will likely increase the cost per board further.
