maybe adding 12 groups of vias, even though there are 11 charlieplexed groups will make it easier to route around the hour LEDs? this PCB is starting to look like a @welshpixie mandala
#Kicad friends: is there a way to request tented vias on only one side? I'd like the spiral to be shiny on the top and covered on the bottom
thanks to a suggestion from @marble and the power of python, there are now a gross number of small circles in the F.Mask layer to un-tent the vias on only one side of the board.
All of the test Charliewatch boards fab'ed and assembled by Aisler work perfectly (other than things that I broke, like not noticing that this MSP430 requires load caps for the crystal). For the next rev I want to squeeze the LEDs closer together to shrink the watch face a bit, which might require violating the ERC.
@th omfg this is gorgeous! 🤩✨
The original Charliewatch boards, also with 0603 LEDs, fit entire inside the circle of the new layout. Despite increasing to 132 LEDs, it should still be routable on the two layers, assuming the fab will put them that close together.
