What will you mostly use it for?
The K3 Max is the more suitable primary keyboard for gaming, office work, programming, and travel, mainly because it provides a complete layout and wireless options. The DOIO is better considered as a supplementary macro controller, with its 12 keys and knob in a compact aluminum case. For modding, both offer hot-swap and firmware customization, but their switch compatibility differs substantially. Content creators can choose based on whether they need extra dedicated controls or a full keyboard.

DOIO KB12 01 vs Keychron K3 Max: your questions
No. The DOIO KB12 01 is a macropad with 12 keys and a knob, not a full keyboard. Its compatibility rules specifically note that it is macropad-only.
Keychron lists the K3 Max as an 84-key, 75% keyboard. It also includes multimedia keys, but no numpad.
The K3 Max supports Bluetooth and 2.4 GHz wireless as well as wired use. The DOIO KB12 01 is wired only and connects over USB-C.
The K3 Max is listed with ISO variants including UK, DE, Nordic, and SW, as well as ANSI. The DOIO KB12 01 has no ISO layout options.
Both models list hot-swappable support. The DOIO vendor description specifies most 3-pin and 5-pin mechanical switches, while the K3 Max is restricted to Gateron or Keychron low-profile mechanical switches.
No. The K3 Max compatibility rules specify low-profile switches and keycaps only, so standard MX keycaps will not fit. Keychron describes its included caps as low-profile double-shot PBT.
The K3 Max has north-facing LEDs, and its compatibility rules warn that Cherry-profile keycaps can hit the switch housing. Consider that limitation before choosing replacement keycaps.
Both products list QMK and VIA support. The DOIO vendor description also identifies VIA programmable layers, while Keychron describes QMK and its Launcher web app for remapping and macros.
The K3 Max offers Bluetooth and 2.4 GHz wireless operation and has a stated 1550mAh battery. The DOIO is narrower, but its 12-key macropad layout and wired-only connection make it an accessory rather than a standalone travel keyboard.
No. The K3 Max compatibility rules specify that it has no numpad. Its layout is 75% with 84 keys.
The DOIO product description identifies it as a 12-key-plus-one-knob macro keyboard and describes customizable control functionality. The source does not specify a fixed default function for the knob.
The K3 Max is the more complete gaming option here, with an 84-key layout and a listed 1000 Hz polling rate in 2.4 GHz and wired modes. The DOIO is a 12-key macro pad, so it is better suited to adding controls alongside a separate keyboard.
