So here is HQB15 v2.
This board is provided as is, and yet untested
Partlist and Firmware see post#84
.
.
Changes from v1 to v2:
Size increased to 15.6mm, the copper GND ring should now result in full 15.0mm
PAM2803 now has a Pin1 dot that appears on the board
Several component positions slightly adapted
A lot of paths widened
GND vias doubled and rearranged
.
The yellow circle is not in the actual board, it just indicates 15.0mm
.
