KEEBD Reviung 39 II
39
- Ultra-compact 39-key layout maximizes desk space.
- Includes FR4 switch plate and acrylic bottom plate for a firm typing feel.
- Kailh hot-swap sockets and support for screw-in stabilizers ease assembly.
- Requires sourcing a Pro Micro controller, switches, and keycaps separately.
- The 39-key layout demands heavy reliance on layers for daily use.
- No included stabilizers or LEDs in the base kit.
Get the
KEEBD Reviung 41
41 Key Layout Choice
- 41-key layout offers two more keys than the Reviung 39 for slightly easier layer access.
- Includes an FR4 switch plate for consistent mounting.
- Features the same Kailh hot-swap sockets and stabilizer support as the Reviung 39.
- Also a barebones kit, requiring a separate controller, switches, and keycaps.
- The vendor description notes a customer review mentioning it does not come with LEDs or extra plates.
- Still a 40% keyboard, lacking dedicated number and navigation rows.
Select the Reviung 41 if you value having two additional physical keys to potentially simplify your layer mappings. Opt for the Reviung 39 MKII if you want the most minimalist footprint possible. Be prepared to source all electronic components and keycaps for either, as they are true DIY kits.

What will you mostly use it for?
The Reviung 41 holds a slight edge for office and programming use due to its two extra keys, which can reduce layer complexity. For travel, the Reviung 39 MKII's minimalism is a minor advantage. For gaming, modding, and content creation, the kits are functionally equivalent, with the choice boiling down to key count preference within an otherwise identical DIY platform.
It's a tie
- Both require extensive layer usage for gaming keys due to their 40% size.
- Identical hot-swap sockets allow for the same switch choices.
- No inherent latency or polling rate advantages are stated for either model.

KEEBD Reviung 39 II vs Reviung 41: your questions
The main difference is the key count. The Reviung 39 MKII is a 39-key board, while the Reviung 41 has 41 keys. Their vendor descriptions show they share identical core components like the acrylic case, FR4 plate, hot-swap sockets, and optional RGB support.
Both are DIY barebones kits. According to the vendor listings, they require you to source and install a Pro Micro controller, MX-style switches, and keycaps separately. The kits include the PCB, plate, case, and mounting hardware.
The base kits do not include RGB LEDs. The vendor descriptions list 11x WS2812B RGB LEDs as an optional separate purchase for adding rear-facing drop-in lighting to either model.
Both PCBs support screw-in stabilizers. The vendor lists a 2u clip-in stabilizer as an optional item for creating a spacebar, indicating compatibility with standard MX-style stabilizers.
Yes. Both kits include an FR4 switch plate and an acrylic bottom plate, according to their included parts lists. The Reviung 41 listing also mentions 'Plastic' as a plate material, but the specific kit item is FR4.
No. The vendor descriptions for both state that precompiled firmware can be found via a linked source, implying you need to flash it onto the Pro Micro controller yourself after assembly.
Both use Kailh hot-swap sockets, which are compatible with standard 3-pin and 5-pin MX-style switches. They require standard MX keycaps, with 39 needed for the Reviung 39 and 41 for the Reviung 41.
Possibly. An optional 'EZ-Solder Header' is listed for both kits, which the vendor description says can enable controller hot swap. This would allow you to remove the Pro Micro without desoldering.
They are equally complex for a first build. Both require soldering diodes and hot-swap sockets onto the PCB, then assembling the case. The Reviung 41's two extra keys involve marginally more soldering but follow the same process.
No wireless capability is mentioned in the specifications or vendor descriptions. Both kits are designed for a wired connection using a Pro Micro controller, which typically connects via USB-C or micro-USB.
Unlike traditional row-staggered keyboards, a column-staggered layout aligns keys in vertical columns that follow the natural arc of your fingers. Both the Reviung 39 and 41 use this ergonomic design, which can be more comfortable for some typists.
The vendor description specifies the included acrylic controller cover is 'Blank/Clear.' The finish of the main bottom plate is not explicitly stated, but it is likely clear acrylic to showcase the internal components.
