Ploopy has announced the Bean, an open-source pointing stick mouse. The device is designed for users who prefer a TrackPoint-style input over a traditional mouse.
Bean features a silicone TrackPoint and four Omron switches.
The Bean features a silicone TrackPoint with 11mm of axial travel. It uses a Texas Instruments TMAG5273 Hall effect sensor with a 20kHz sampling rate and 12-bit resolution, capable of detecting movements as small as 3 micrometers. The mouse has four buttons equipped with Omron D2LS-21 switches. It runs QMK firmware and supports VIA for key remapping.
