The DZ17 is the wireless version of the DS17: nRF52840 MCU, USB wired + Bluetooth 5.0 dual-mode, 5 monochrome status LEDs, ZMK firmware with live keymap editing via ZMK Studio.

Designed around one word — pure low power: no RGB, no screen, no extra load; indicators only confirm a state and then turn off. Measured standby current ~20 µA (Bluetooth always connected, instant-on), active average ~700 µA. ZMK open-source firmware: you can always remap, build and fix it yourself.
