Ferris Sweep MX Kit - Clean Design, Maximum Comfort
The simple design won me over right away. The build process was straightforward - just a single evening of soldering. I have the MX version, the switches are soldered directly to the PCB. I really appreciate the minimalism: no diodes, no LEDs, no OLED screen—just the essentials. Visually, I like that both controllers face downward on the MX build, though this does mean the buttons on the RP2040 Pro-Micro controller aren’t accessible. Because of this, socketing the controller is doubly important.
On the software side, things weren’t quite as simple. I prefer compiling my own firmware, and it took me a while to figure out how to adjust the QMK settings for this board. In the end, I settled on the following pin mapping:
#undef DIRECT_PINS
#define DIRECT_PINS { \
{ E6, F7, F6, F5, F4 }, \
{ B1, B3, B2, B6, D3 }, \
{ D1, D0, D4, C6, D7 }, \
{ B4, B5, NO_PIN, NO_PIN, NO_PIN } \
}
#undef DIRECT_PINS_RIGHT
#define DIRECT_PINS_RIGHT { \
{ F4, F5, F6, F7, E6 }, \
{ D3, B6, B2, B3, B1 }, \
{ D7, C6, D4, D0, D1 }, \
{ B5, B4, NO_PIN, NO_PIN, NO_PIN } \
}
Typing on it feels excellent - the aggressive stagger is very comfortable for me. The only drawback I’ve noticed is the weight. The keyboard out of the box is very light, and I miss the stability that a bit of weight would bring.
