Just added another PCB layout with conventional components (through-hole) and single sided for ease of diy board manufacturing. The board measures 1.8 x 2.6 inches (roughly 40 x 70 mm) and has connections for VCC and RESET pins. The remaining pins were kept at the same configuration as the original board which means 2 rows of pins, A1-A9 and B1-B9.

The Eagle files are on github under "circuit" folder.
