(side without copper) so that the metal bits are flush with the plastic which keeps
the pins together (plastic on the top), then solder the pins on the bottom side. You
may then take off the plastic from the top side and slide it in from the bottom side.
* You may need to flip the image before the transfer to the copper board, because
the copper is on the bottom side.

stored in the gerbers directory and upload it to the manufacturesr's site of your choice.
Use fab_1_1.zip for smaller PCB design that allows to program 16V8 devices only.
Use fab_2_0.zip for a bigger design that allows to program 16V8 and 22V10 devices.
Use fab_1_2.zip for smaller PCB design that allows to program 16V8 devices only.
Use fab_2_1.zip for a bigger design that allows to program 16V8 and 22V10 devices.
The price difference should be minimal as both designs fit within 100x100 mm area.
* Dimensions of the fab_1_1 board is 55x53 mm
