KEEBD Contra vs Mechboards Gherkin Kit40% vs 30% Ortholinear DIY Kits

The KEEBD Contra may be slightly better for a first build. It includes more components like a separate plate and bottom, and its 40% layout is less intimidating than the Gherkin's extreme 30-key layout. However, the Gherkin's build process is also documented and its lack of stabilizers simplifies one step.

According to the vendor listing, you need a Pro Micro controller, MX switches, MX keycaps, and a 2u clip-in stabilizer for the spacebar. The kit does not include these items.

The Mechboards description states you need 30 MX switches, 30 keycaps, and a USB cable. The kit includes the RP2040 controller, so you do not need to buy one separately.

No, both the KEEBD Contra and Mechboards Gherkin are soldering kits. The vendor description for the Contra mentions an optional EZ-Solder Header to enable controller hot-swapping, but the switches themselves must be soldered.

The KEEBD Contra is a 40% ortholinear keyboard with 47 or 48 keys. The Mechboards Gherkin is a 30-key ortholinear keyboard, which is significantly smaller.

No, neither kit includes a full set of keycaps or switches. The Contra includes one 6x6 tactile switch as a sample. Both require you to purchase MX-compatible switches and keycaps separately.

An ortholinear layout arranges keys in a straight grid, with each key aligned vertically and horizontally. This differs from the staggered rows found on standard keyboards. Both the Contra and Gherkin use this layout.

Yes, but it requires significant adaptation. With only 30 physical keys, you must use function layers to access numbers, symbols, and punctuation. The vendor description notes that layers are normal for small keyboards and can be fast once learned.

The KEEBD Contra uses a two-piece design with an FR4 switch plate and a separate acrylic bottom plate, connected by standoffs. The Mechboards Gherkin uses a single 'Plate Case' unit, which combines the plate and case.

You need to flash firmware for both. The Contra vendor page links to precompiled firmware, but you must flash it to the Pro Micro controller yourself. The Gherkin build instructions include flashing the included RP2040 controller as a step.

The Mechboards Gherkin is more portable due to its smaller 30-key size. Its integrated Plate Case design may also contribute to a slimmer profile, making it easier to transport than the two-piece 40% Contra.
