  • Connect three devices via Bluetooth 5.0, 2.4 GHz or wired USB-C
  • Swap TTC Neptune switches without soldering for custom feel
  • 22 RGB effects with five brightness levels and music sync
  • 800 mAh battery lasts 10 days with lights off

Compact numeric keypad for mobile professionals

The fopato S21 is a 21-key numpad that connects through Bluetooth5.0, 2.4 GHz wireless or a USB-A to Type-C cable. It pairs with Windows, Android, macOS, iPadOS and iOS devices and can switch between multiple paired hosts using the FN+1, FN+2 or FN+3 shortcuts.

Hot-swappable switches and three connection modes

The board uses TTC Neptune switches rated at 41 gf actuation force with a 2.0 mm pre-travel distance. Every key socket is hot-swappable so switches can be changed without soldering. The three connection methods share the same 800 mAh rechargeable battery, which lasts up to 10 days with lighting off and 7 days with lighting on.

Upgrades a laptop’s missing number row

Users who regularly enter spreadsheets, accounting data or code gain a dedicated numeric cluster without carrying a full-size keyboard. The gasket-mounted structure and 22 RGB lighting effects with five brightness levels add desk appeal, but the device lacks programmable macros or QMK/VIA support, so advanced customisation is not possible.
