// Description:
// A reversible footprint for the nice!nano (or any pro-micro compatible
// A single-side or reversible footprint for the nice!nano (or any pro-micro compatible
// controller) that uses jumpers instead of two socket rows to be reversible.
//
// Note that the extra pins are *ONLY* compatible with nice!nano boards and not with
// clones like the Supermini, which has pins in a slightly different position.
//
// This is a re-implementation of the promicro_pretty footprint made popular
// by @benvallack.

// - Add single side (non-reversible) support
// - Add ability to mount with MCU facing towards or away from PCB
// - Add ability to show silkscreen labels on both sides for single side footprint
// - Add extra pins (P1.01, P1.02, P1.07) when footprint is single-side
// - Add extra pins (P1.01, P1.02, P1.07) when footprint is single-side or reversible
// (only required jumpers)
//
// # Placement and soldering of jumpers
//
// The footprint is meant to be used with a nice!nano (or any other pro micro
// compatible board) that is placed on the top side of the PCB with the
// components facing down.
//
// This means when you look down at it, the RAW pin is in the upper left
// corner and the 006 pin in the upper right corner.
//
// To make it work in this configuration, you solder the jumpers on the
// OPPOSITE side.
//
// The silkscreen labels are displayed on the opposite side of the MCU, when
// it's facing down. This is so that one can solder all components and jumpers
// on the back side, and be able to read the correct labels to do tests.
//
// Due to the way how this footprint works, you can also place it with the
// components facing up or even at the bottom. You just need to make sure you
// solder the jumpers on the correct side. Remember that the silkscreen matches
// what the jumpers enable for every through-hole.
// The reversible footprint is meant to be used with jumpers on the
// OPPOSITE side of where the nice!nano (or pro-micro compatible board) is
// installed. The silkscreen labels will also match the board when read on
// the opposite side. This is to have all jumpers and components to solder on
// the same side, and be able to read the correct labels of the MCU to do
// tests with a multimeter.
