Polaris Hotswap Replacement PCBs — FJLaboratories
Aftermarket Replacement Hotswap PCBs for the ai03 Polaris Gasket Mount Keyboard — Felix Jen
Released on June 04, 2021
ai03 Polaris Hotswap PCBs
Designed and produced by FJLaboratories, these aftermarket hotswap PCBs were made to fit the ai03 Polaris gasket mount keyboard. These PCBs use high grade FR4 for long term durability and heat tolerance even in intense desoldering. Furthermore, these PCBs are only 1.2mm thick—like the original Polaris PCBs—for ultimately flexibility. Revolutionary multi-layout hotswap support was added without compromising usability of any of the positions. Reinforcement was added to the underside of the hotswap sockets to reduce chances of damage during repeat insertions.
