Lily 58 Wireless SMT PCB – Assembled Hot-Swap, ZMK Compatible

Meet the Lily 58 Wireless SMT PCB, a fully assembled, hot-swappable wireless PCB built for the Lily 58 layout. It ships pre-flashed with ZMK (ZMK Studio Ready) and requires no soldering, no TRRS cable between halves, and no firmware setup. Drop it in a compatible case, add switches and keycaps, pair, and type. Whether you are looking for a reliable Wireless Lily 58 or a drop-in wireless upgrade for your existing case, this PCB delivers a premium, cable-free experience. Why This Board? Zero soldering: Factory-assembled with hot-swap sockets. True cable-free halves: Wireless between halves. No TRRS. ZMK pre-flashed: Ready for pairing and live remapping in ZMK Studio. Universal switch support: MX, Choc v1, and Choc v2 on one PCB. Case friendly: Works with Lily Pad, LuLu and most standard Lily 58 cases. Expandable: 8-pin header for screens and peripherals. Key Features Hot-swap sockets: Build and iterate without touching a soldering iron. Hot-swap sockets: Build and iterate without touching a soldering iron. ZMK out of the box: Ships pre-configured and compatible with ZMK Studio for real-time keymap changes. Wireless by design: No interconnect cable between halves. MX + Choc footprint: Custom hot-swap footprint supports MX, Choc v1, and Choc v2. Spacing is always 19.05 mm. Case compatibility: Backwards compatible with Lily Pad and most 3D-printed, FR4, or stacked acrylic Lily 58 cases. Display/peripheral header: 8-pin expansion header for nice!view or e-ink displays and other add-ons. Power made simple: Dedicated on/off switch positioned for easy access in common cases. Battery options: JST-PH micro connector and solder pads for 3.7 V LiPo packs.

What's Included? 1x Left Lily 58 Wireless SMT PCB (assembled) 1x Right Lily 58 Wireless SMT PCB (assembled) Frequently Asked Questions Is the Lily 58 Wireless SMT PCB fully assembled? Yes. It’s a fully assembled, hot-swap wireless Lily 58 PCB with the microcontroller, wireless module, and sockets pre-installed. No soldering required. What firmware does it use? It ships pre-flashed with ZMK and works with ZMK Studio for real-time keymap changes, ideal for a wireless split Corne build. Will it fit my existing Lily 58 case? It works with Lily Pad and most standard Lily 58 cases, including many 3D-printed, FR4, and stacked acrylic designed. In order to use the PCB with a Lily Pad, a Wireless Plate is required. What batteries does the PCB support? 3.7 V LiPo packs via JST connector or the +/- solder pads. Typical max sizes: Choc ~22×12×3 mm, MX ~22×12×6 mm. Which switches are supported? MX, Choc v1, and Choc v2 on the same PCB. Spacing is always 19.05 mm. Can I add a display? Yes. An 8-pin header supports screens such as nice!view and other peripherals. VCC is switchable for power savings. What is the pinout for the expansion header? There is an 8-pin header on each side intended for screens (like nice!view) or other peripherals. The pinout from left to right is: 0.07, 0.21, 0.12, 0.23, VCC (Switched), GND, 0.19, 0.05. The VCC pin is controlled via GPIO pin 0.31 to save power. More quesitons? Check the Docs for the PCB
