What will you mostly use it for?
The KM16 Pro secures the win in both Gaming and Content Creation due to its 1000 Hz polling rate and three highly versatile knobs that excel for shortcuts and live control. The KM40 dominates Programming and Travel thanks to its complete 40% layout, deep layer customization, and larger 2000 mAh battery. For Office work, both offer PBT keycaps and flexible programmability leading to a tie, and for Modding, both platforms are equally open with hot-swap PCBs and QMK/VIA. The core choice is whether you need a dedicated macro tool or a standalone minimalist keyboard.

MMD KM16 Pro Numpad vs KM40: your questions
Yes, the vendor description states that the KM16 Pro can be configured as a classic numpad using VIA. The 16 keys become digits 0-9 and operators, while the knobs can handle functions like Tab, Enter, or comma.
A 40% keyboard like the MMD KM40 is a standalone typing device with 44 keys that includes all letters, accessed via layers for numbers and symbols. A macropad like the KM16 Pro is a companion device with only 16 keys and 3 knobs, intended for shortcuts or as a numpad, not for full typing.
Yes, both the MMD KM16 Pro Numpad and the MMD KM40 are listed with QMK and VIA support. This allows for full key remapping, macro creation, and layer configuration through a browser without installing drivers.
The MMD KM40 has a larger 2000 mAh battery, while the KM16 Pro has a 980 mAh battery. Based on the provided specifications, the KM40 should offer longer runtime between charges, though actual battery life depends on usage and RGB settings.
No, the MMD KM16 Pro does not have a screen according to the metadata. The KM40 also lacks a screen. Both rely on RGB or layer indicators for visual feedback.
Yes, both keyboards are hot-swappable with 5-pin MX standard PCBs, according to the vendor descriptions. This allows you to change switches without soldering for experimentation or customization.
The MMD KM40 comes with 1.7 mm thick five-sided dye-sub PBT keycaps. These are durable, with legends that are embedded into the material so they won't wear off over time, and the extra thickness contributes to a fuller sound and feel.
At only 200g and with dimensions of 50 x 150 x 120 mm, the KM16 Pro is very lightweight and compact for travel. However, note that it is an accessory and requires a separate keyboard for typing, so it works best as a supplement to a laptop or tablet.
Yes, the vendor listing states that the KM40 supports Bluetooth 5.0 with up to 3 devices paired simultaneously. You can switch between connected devices using a key combination, making it convenient for multi-device setups.
The MMD KM16 Pro uses a gasket mount system on an FR4 plate. This design cushions the PCB with soft rubber gaskets for a slightly bouncy typing feel and a refined sound profile, as described in the vendor details.
Yes, the KM40 can be used for gaming, as it supports tri-mode connectivity and hot-swappable switches. However, its polling rate is not specified in the provided data, and the 40% layout may require layer access for number keys, which could be a drawback in some games.
The MMD KM16 Pro is offered in five colors: Black, Silver, White (labeled Cream in the vendor text), Mint, and Pink. The MMD KM40 comes in six colors: Black, Silver, White, Pink, Red, and Green.
