Ploopy Bean Brings TrackPoint-Style Pointing Stick to USB with Open-Source Firmware
Ploopy launches the Bean, a USB pointing-stick mouse with four programmable buttons and a 3D-printed case. It uses a Raspberry Pi RP2040 MCU, a TMAG5273 sensor for precise movement, and runs open-source QMK firmware (configurable via VIA) with all design files on GitHub; Early Access orders are shipping, but units sold out with Tier A/B timelines. The device is CAD 70 (~$52) and targets users who want a Lenovo TrackPoint-style input with customizable controls.
