What will you mostly use it for?
The B3 Pro is the more suitable pick when gaming or programming calls for a full typing layout in one board. For office use, the right choice depends on whether you need general typing or a dedicated number pad. The V0 Ultra is easier to carry as a small add-on and offers more hardware customization. Its numpad-only layout limits it as a standalone keyboard.
Pick the Keychron B3 Pro
- The B3 Pro has a 75% layout, making it the more complete option for general keyboard input.
- The V0 Ultra is a numpad, though its 8000 Hz polling rate is a specified advantage for responsiveness.

Keychron B3 Pro vs V0 Ultra Numpad: your questions
The B3 Pro has a 75% layout and multimedia keys, so it is the more complete typing board in this comparison. It does not include a numpad.
No, the V0 Ultra is a numpad-only device. It is suited to adding number-pad input rather than replacing a full keyboard.
The V0 Ultra has hot-swappable switches. Keychron says its switches can be changed without soldering, with support for many 3-pin and 5-pin MX-style mechanical switches.
The B3 Pro's switches are soldered, so changing them requires soldering. It is not listed as hot-swappable.
The V0 Ultra lists an 8000 Hz polling rate, while the B3 Pro lists 1000 Hz. The V0 Ultra is a numpad, so the higher rate does not make it a full keyboard.
No, the B3 Pro is listed without RGB. The V0 Ultra has south-facing RGB lighting.
The V0 Ultra's south-facing LEDs may leave shine-through legends dark. Some sculpted keycaps can also clip the LEDs.
The V0 Ultra measures 29 x 118 x 139 mm and weighs 310g. The B3 Pro measures 3 x 100 x 380 mm and weighs 410g, but the two devices serve different layout roles.
No, the B3 Pro is limited to low-profile switches and keycaps. Standard MX keycaps will not fit.
The B3 Pro is the more practical choice for general programming input because it has a 75% layout. The V0 Ultra is a numpad, which can add dedicated number entry but is not a standalone typing board.
The V0 Ultra is the stronger fit for switch changes because it is hot-swappable and has a gasket mount with a polycarbonate plate. The B3 Pro's switches are soldered and it only accepts low-profile switches and keycaps.
The V0 Ultra cannot replace the B3 Pro as a general typing keyboard because it is numpad-only. Choose the B3 Pro for its 75% layout and multimedia keys, or the V0 Ultra to add number-pad input.
