Jamesdonkey A3 3.0 vs R3 TMR HE: your questions
The Jamesdonkey A3 3.0 offers wireless connectivity. It supports Bluetooth, 2.4 GHz, and wired USB connections, and includes a 3750mAh battery. The R3 TMR HE is a wired-only keyboard.
Yes, the Jamesdonkey R3 TMR HE features hot-swappable sockets. However, it is designed for its specific Gateron Golden Dragon magnetic (Hall Effect) switches, which may limit compatibility with standard mechanical switches.
The vendor description for the Jamesdonkey A3 3.0 mentions an 'ultra-low latency performance' and 'delay-free response,' but does not specify a numeric polling rate. The R3 TMR HE explicitly lists an 8000 Hz polling rate.
Yes. The Jamesdonkey A3 3.0 supports QMK, which is an open-source firmware that allows for extensive key remapping, layer creation, and macro programming through a web-based driver.
Hall Effect switches, like the Gateron Golden Dragon magnetic switches in the R3 TMR HE, use a magnetic field and sensor to register keystrokes. This allows for features like rapid trigger, adjustable actuation points, and theoretically longer durability as there is no physical contact for actuation.
This depends on preference. The A3 3.0 comes with TTC Iron V2 switches and a five-layer padding for a dampened sound. The R3 TMR HE has customizable magnetic switches and a four-layer filling. The A3's 75% layout may be more comfortable for some due to its dedicated navigation keys.
