Way back in 2012, I wrote about Microchip MGC3130 3D Gesture Controller with “GestIC technology” which allows you to make gesture up to 15cm from the surface and at lower power in order to control devices in a new way. At the time, the chip was said to sell for $2.26 in large quantities, and the evaluation kits went for $169 and up. I’m writing about MGC3130 about 5 years later, as Seeed Studio has started taking pre-orders for a $25.89 Flick HAT board based on the solution, and designed for Raspberry Pi boards, or other boards with a compatible 40-pin “GPIO” header featuring an I2C interface.
Flick HAT 3D Tracking & Gesture HAT specifications & features:
- Chip – Microchip MGC3130 3D Tracking and Gesture Controller
- Tracking / Gesture Features
- 3D tracking
- Gesture sensing up to 15cm: Swipe (east to west, west to east, north to south, south to north), tap and double tap (center, east, west, north, south), airwheel (clockwise, anti-clockwise)
- Touch and Tap sensing (center, east, west, north, south)
- Position rate – 200 positions / second
- Spatial resolution – up to 150 dpi
- Host Communication Interface – I2C
- Header – 40-pin header compatible with Raspberry Pi B+, Pi 2 model B, Pi 3, and others.
