Updating OP with new renders and examples:
CoreJamón is built around its Core kit, which is the starting point for everyone. With just 116 keys, it provides coverage for most keyboards ranging from 60% to TKL form factors, including those with a WKL bottom row, split backspace, or stepped caps lock.
NumpadThe numpad extension kits adds layout support for 1800, 96-key, and full-sized keyboards. An accent Enter key and extra compatibility keys have been included.
UK ISOA small extension kit that adds UK layout support for international layouts. The kit comes with two ISO Enter accent keys, and an extra R1 1.00U `¬ key for color symmetry purposes.
Forties & SplitThe Forties & Split kit was designed with two purposes. The first one is to provide layout support for ortholinear and other 40% keyboards, such as Planck, Vortex Core, or Percebe.
The second one is to add all the necessary keys, including a second B that many of them use, for ergonomic and split keyboards.
SpacebarsThe spacebar kit provides a set of accent 2.00U, 2.25U, 2.75U, 6.25U and 7.00U spacebars. Additionally, it extends Jamón’s layout compatibility by including two 6.00U spacebars (one with a center stem and another with an off-center one) so you could cover an Uniqey C70, and Cherry G80-1800 boards.
JamoneltiesA novelty kit with a set of accent arrows, Esc, and Enter keys, a R3 Ñ with ANSI sublegends, and two Jamón related custom keycaps. The kit also comes with four F-Row bacon strips, eggs, and bottom row bacon modifiers.
