Distance Pulsed Radar Breakout - A111 For Raspberry Pi (SparkFun)

The SparkFun A111 Pulsed Radar Breakout is a high-precision sensor module that uses 60GHz pulsed coherent radar (PCR) technology for distance measurement, gesture, motion, speed, and material detection. Unlike traditional ultrasonic or infrared sensors, it provides millimeter-level accuracy up to 2 meters. The single-chip radar includes an integrated antenna and communicates via a high-speed SPI interface supporting clock speeds up to 50MHz, suitable for real-time applications.

Package Includes

  • 1 × SparkFun Pulsed Radar Breakout Board - A111
  • 1 × Female Header - 26-pin (2x13)
  • Note: Raspberry Pi board is not included.
