113 Grams, Recessed TMR Sticks, and Optical Triggers: JSAUX Packs Full Gamepad Controls Into the Pocket-Sized VOIDJOY SkyLark S1 Pro
Slipping a full-featured controller into a jacket pocket without snagging its thumbsticks or weighing down a travel bag has long been a frustrating compromise for portable gamers. Under its controller-focused VOIDJOY sub-brand, hardware accessory maker JSAUX GAMING is tackling that physical bottleneck head-on with the SkyLark S1 Pro, a 113-gram multi-platform gamepad built for players jumping between handheld PCs, tablets, and smartphones.
A 24mm Pocket Footprint That Pairs Two Controllers to One 2.4 GHz Receiver
Where most ultra-portable controllers strip away analog triggers, rumble motors, or rear paddles to shave off a few millimeters, JSAUX GAMING engineered a complete layout inside a 133 mm x 75 mm x 24 mm shell. As Winnie Chen, Marketing Communications Manager at JSAUX GAMING, explained in the company's official announcement: "Portability should not come at the expense of functionality. We designed the SkyLark S1 Pro to be as easy to carry as a phone while still delivering the control players expect from a serious gamepad."
To keep travel setups clutter-free, the SkyLark S1 Pro features tri-mode connectivity across wired USB-C, Bluetooth (with multi-device memory for instant reconnection), and 2.4 GHz wireless rated at a 1,000 Hz polling rate. Its standout hardware trick lies in that 2.4 GHz dongle: two SkyLark S1 Pro controllers can connect simultaneously through a single receiver. Whether you are gaming on a docked Nintendo Switch or taking advantage of the growing SteamOS and Linux handheld ecosystem on a Steam Deck with limited USB ports, that dual-link capability makes it effortless to fire up local co-op sessions in It Takes Two or Overcooked! without carrying a USB hub.
Recessed TMR Magnetic Thumbsticks and Dual-Travel Optical Triggers
Traditional protruding analog sticks are always the first component to suffer when a gamepad is tossed into a backpack. To solve this, VOIDJOY equipped the SkyLark S1 Pro with recessed TMR (Tunneling Magnetoresistance) thumbsticks set directly into the controller housing. The lowered profile prevents accidental inputs and physical snags in transit while delivering higher resolution, lower power draw than standard Hall Effect sensors, and complete immunity to stick drift.
Up top, the gamepad integrates optical linear triggers paired with physical travel-stop switches offering two distinct actuation modes:
- Long-Travel Analog Mode: delivers smooth, gradual input modulation tailored for throttle and brake control in racing and simulation titles.
- Short-Travel Quick Mode: cuts trigger travel distance down for rapid actuation in first-person shooters and fast-paced action games.
Despite its 113-gram frame, the controller packs six-axis gyro motion controls, dual vibration motors, programmable rear buttons (ML and MR), and a 1,000 mAh battery rated for roughly 10 hours of playtime. Players can also fine-tune button remapping, dead zones, stick sensitivity curves, and per-game profiles through the companion KeyLinker mobile app.
Platform Compatibility, Pricing, and Launch Discount
The VOIDJOY SkyLark S1 Pro is compatible with Windows PCs, Steam Deck, Nintendo Switch (and Switch 2), Apple iOS/iPadOS devices, and the wider Android portable gaming ecosystem. It carries a standard retail price of $49.99, and JSAUX GAMING is currently offering a limited-time launch price of $44.99 (10% off) when buyers apply the promo code VOIDJOY10 on the official store.

My Take on the Spec Sheet
On paper, JSAUX is addressing the exact mechanical compromises that have held pocket-sized controllers back for years. Swapping out fragile protruding sticks or mushy flat sliders for recessed TMR magnetic sensors inside a 24mm shell tackles the biggest durability headache of portable play. Factor in dual-travel optical triggers and a 1,000 Hz 2.4 GHz dongle capable of linking two gamepads to a single USB-C port, and the sub-$50 price point looks genuinely compelling for handheld owners. In full transparency, we have not yet had the VOIDJOY SkyLark S1 Pro on our lab bench, so real-world ergonomics over multi-hour sessions and the physical tension of those recessed TMR sticks remain to be tested. If the VOIDJOY team would like to send a review unit over to our lab so we can put its sticks, optical triggers, and wireless latency through their paces, our door is wide open.
