Layout & compatibility
The Yier and Bubu 5108B Plus supports Bluetooth 5.0, 2.4GHz wireless and wired USB-C. Its hot-swap sockets support 3-pin and 5-pin mechanical switches, so compatible switches can be changed without soldering. Akko Cloud Driver supports customization through Mac, Windows and Web interfaces. Replacement keycap sets should provide complete 108-key full-size coverage.
Performance & experience
FULL-SIZE + TRI-MODE
Full-Size Without Giving Up Modern Connectivity
The 5108B Plus keeps the numpad, navigation cluster and function row while still offering the connection options expected from a modern wireless mechanical keyboard.
Use USB-C for a fixed wired setup, 2.4GHz for a dedicated wireless receiver, or Bluetooth when switching to a laptop, tablet or other compatible device. For buyers who genuinely use a full-size layout, that combination is more useful than shrinking the keyboard just for portability.
- 108-key full-size layout
- USB-C, 2.4GHz and Bluetooth
- 3000 mAh battery
Why it matters: You get the complete 108-key layout without being locked to a single device or connection method.
MOA PBT KEYCAPS
MOA PBT Dye-Sub Keycaps Carry the Theme
The collaboration is expressed most strongly through the keycaps. Akko specifies MOA-profile PBT dye-sub keycaps, combining a rounded sculpted shape with durable PBT material and dye-sublimated legends and artwork.
That matters here because the keycaps are not just a technical component — they are a major part of the reason this edition looks different from a standard 5108B Plus.
- MOA sculpted profile
- PBT material
- Dye-sublimated character artwork
Why it matters: Buy this edition because you want the themed keycap experience, not just because you need another full-size keyboard.
CUSTOMIZATION
Cute Outside, Still Customizable Underneath
The themed design does not turn the keyboard into a closed system. Akko V3 Piano Pro linear switches come installed from the factory, while the 3-pin / 5-pin hot-swap sockets let you try other compatible mechanical switches without soldering.
Programmable RGB adds another layer of personalization through Akko Cloud Driver, so you can keep the Yier and Bubu case and keycaps while changing the switch feel later.
- V3 Piano Pro linear switches
- 3-pin / 5-pin hot-swap
- Programmable RGB + Akko Cloud Driver
Why it matters: You can preserve the themed look while changing compatible switches and supported lighting or key settings later.

LIMITED-EDITION THEME
The Collaboration Is the Main Product Story
The biggest reason to choose this edition over a standard full-size keyboard is the Yier and Bubu theme itself. The color palette, character artwork and keycap legends extend across the entire 108-key layout, making the keyboard a visual centerpiece rather than a generic board with a small collaboration badge.
Yellow and Pink give buyers two distinct directions for a themed setup, while the large full-size canvas gives the artwork more room to appear across the alphanumeric area, navigation cluster and numpad.
- Character-led limited-edition design
- Yellow and Pink colorways
- Theme extends across a complete 108-key layout
Why it matters: If desk aesthetics are part of the buying decision, this model gives the collaboration much more visual presence than a subtle themed accent.
Check before buying
- The 108-key layout takes much more desk space than 75%, TKL or compact keyboards.
- At roughly 442 mm wide and about 1.2 kg, it is better suited to a permanent desk than frequent travel.
- This PDP is for the 5108B Plus; the newer 5108 V5 is a separate model.
