JSAUX Launches SkyLark S1 Pro Controller and Elite Extender With TMR Sticks for Switch Pro Controllers

SAUX is moving deeper into gaming hardware with the launch of its new VOIDJOY controller brand, and its first two products are aimed at players who want more control without moving to expensive premium Controllers. The company has introduced the VOIDJOY SkyLark S1 Pro Portable Controller and the VOIDJOY Elite Extender for Switch Pro Controller, with both products going on sale September 1.

The SkyLark S1 Pro is the more conventional of the two, but its compact design and magnetic TMR sticks give it some useful hardware features for its $49.99 price. The controller supports 2.4GHz wireless, Bluetooth, and USB-C wired connections, allowing it to be used with Windows PCs, Nintendo Switch, Switch 2, SteamOS, Android, and Apple devices. It is not compatible with Xbox consoles or PlayStation 5.

VoidJoy has fitted the S1 Pro with recessed dual TMR sticks that use magnetic sensing. The lower stick position helps keep the controller compact, while the optical triggers can be switched between two modes. Analog Mode provides longer travel for pressure-sensitive input, which can be useful in racing and simulation games, while Quick Mode reduces the trigger travel for faster input in shooters and action games.

The controller also includes ML/MR expansion buttons that can be assigned to different functions through the KeyLinker app. Users can adjust button mappings, stick sensitivity, dead zones, trigger settings, vibration, lighting, macros, and turbo functions. The controller can also record macros containing up to 42 button-sequence entries.

For local multiplayer, the included 2.4GHz receiver can pair with two SkyLark S1 Pro controllers at the same time. VoidJoy also supports player-role switching between two connected controllers, allowing players to swap Player 1 and Player 2 assignments without physically exchanging the gamepads.

The second product takes a different route. The VOIDJOY Elite Extender is designed for owners of the original Nintendo Switch Pro Controller who want additional controls without replacing the gamepad. The accessory attaches directly to the controller and adds P1 and P2 rear buttons along with detachable LT and RT shoulder triggers.

The Elite Extender also adds optical analog triggers with 1,280-step sampling, making it possible to get progressive throttle and braking input in supported games. Its KeyLinker support includes button remapping, macros, turbo settings, stick calibration, trigger adjustments, lighting controls, and firmware updates.

Another feature is the integrated 1,800mAh battery, which works alongside the Switch Pro Controller’s own battery to extend gaming time. The 68-gram accessory also supports Android touch mapping, allowing physical controller buttons to be assigned to on-screen controls in compatible mobile games.

The two VOIDJOY products are now available through JSAUX, with the SkyLark S1 Pro priced at $49.99 and the Elite Extender listed at $39.99. JSAUX will also show the new controller lineup at IFA 2026 in Berlin from September 4 to 8, where it plans to preview a modular VOIDJOY PC Controller scheduled for release later this year.

For PC and handheld players, the SkyLark S1 Pro is the more interesting starting point because of its TMR sticks, multiple connection options, and compact design. Meanwhile, the Elite Extender targets a different group: Switch Pro Controller owners who want rear buttons, analog triggers, extra battery capacity, and software customization without buying another gamepad.
