// Description:
// A single-side or reversible footprint for the SuperMini NRF52840 (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 SuperMini NRF52840
// board and not with the Nice!Nano, which has pins in a slightly different position.
//
// This is a re-implementation of the promicro_pretty footprint made popular
// by @benvallack, adapted to match the SuperMini extra pin position.
//
// Pinout and schematics:
// https://wiki.icbbuy.com/doku.php?id=developmentboard:nrf52840
//
// Params:
// side: default is F for Front
// the side on which to place the single-side footprint and designator, either F or B
// reversible: default is false
// if true, the footprint will be placed on both sides so that the PCB can be
// reversible
// reverse_mount: default is false (MCU facing away from the PCB)
// if true, the sockets will be oriented so that the MCU faces the PCB (RAW / B+ is the
// top left pin). This is the most common mounting option for the SuperMini.
// When set to false, the pads will match the datasheet and assume the MCU faces away
// from the PCB (RAW / B+ is the top right pin).
// include_traces: default is true
// if true it will include traces that connect the jumper pads to the vias
// and the through-holes for the MCU
// include_extra_pins: default is false
// if true and if not reversible it will include SuperMini extra pin sockets (P1.01,
// P1.02, P1.07). If the board is reversible, extra pins will be added only if the
// flag `only_required_jumpers` is set to true, and only P1.01 and P1.02 will be
// added to avoid overlap of P1.07.
// only_required_jumpers: default is false
// if true, it will only place jumpers on the first 4 rows of pins, which can't be
// reversed in firmware, i.e. RAW and P1, GND and P0, GND and RST, GND and VCC.
// use_rectangular_jumpers: default is false
// if true, it will replace chevron-style jumpers with rectangual pads
// via_size: default is 0.8
// allows to define the size of the via. Not recommended below 0.56 (JLCPCB minimum),
// or above 0.8 (KiCad default), to avoid overlap or DRC errors.
// via_drill: default is 0.4
// allows to define the size of the drill. Not recommended below 0.3 (JLCPCB minimum),
// or above 0.4 (KiCad default), to avoid overlap or DRC errors.
// Pxx_label, VCC_label, RAW_label, GND_label, RST_label: default is ''
// allows to override the label for each pin
// mcu_3dmodel_filename: default is ''
// Allows you to specify the path to a 3D model STEP or WRL file to be
// used when rendering the PCB. Use the ${VAR_NAME} syntax to point to
// a KiCad configured path.
// mcu_3dmodel_xyz_offset: default is [0, 0, 0]
// xyz offset (in mm), used to adjust the position of the 3d model
// relative the footprint.
// mcu_3dmodel_xyz_scale: default is [1, 1, 1]
// xyz scale, used to adjust the size of the 3d model relative to its
// original size.
// mcu_3dmodel_xyz_rotation: default is [0, 0, 0]
// xyz rotation (in degrees), used to adjust the orientation of the 3d
// model relative the footprint.
//
// @infused-kim's improvements:
// - Use real traces instead of pads, which gets rid of hundreds of DRC errors.
// - Leave more space between the vias to allow easier routing through the middle
// of the footprint
//
// @ceoloide's improvements:
// - Move vias closer to the pads to clear up more space for silkscreen
// - Add ability to use rectangular jumpers instead of chevron-style
// - Add ability to control via size, to free up space for routing if needed
// - Add ability to only have required jumpers and let the rest be handled in firmware
// - 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 or reversible
// (only required jumpers)
// - Upgrade to KiCad 8
// - Adapted to match the SuperMini extra pin positions
//
// # Placement and soldering of jumpers
//
// The reversible footprint is meant to be used with jumpers on the
// OPPOSITE side of where the SuperMini (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.
//
// # Further credits
//
// The original footprint was created from scratch by @infused-kim, but was based on the ideas from
// these other footprints:

// https://github.com/Albert-IV/ergogen-contrib/blob/main/src/footprints/promicro_pretty.js
