 The Iron180 PCB is a F13 TKL PCB with ALPS switches support. It also supports in-switch single-color LEDs and a multi-layout design for default or 7U bottom row, ISO layout, split backspace and right shift.
 
-As of November 2020, the only way to obtain an Iron180 was through the [Group Buy](https://geekhack.org/index.php?topic=109513) which is already over and all spots were filled.
