A111 60GHz Pulsed Radar Breakout

Bring 60GHz radar sensing into your project with the Acconeer A111 single-chip pulsed coherent radar sensor on a SparkFun breakout board. It is suited to high-precision distance measurement, and also supports gesture, motion, material and speed-detection applications at distances up to two metres.

The board includes an integrated antenna, a 1.8V regulator, voltage-level translation, and breaks out all pins from the pulsed radar sensor. Connections are available on both 0.1-inch headers and Raspberry Pi-friendly headers, with a 26-pin -- 2x13 -- header layout intended to sit directly on top of a Raspberry Pi.

For development, Acconeer provides the Python-based Exploration Tool for real-time data collection and visualisation, including distance and presence sensing graphs, sweep counts and communication-port information. The tool supports Windows and Linux and requires Python version 3.6 or later.

Features:

• 60 GHz Pulsed Coherent Radar (PCR) sensor
• Integrated antenna
• Measurement distance up to 2m
• Accuracy down to mm-range
• SPI interface -- up to 50MHz SPI clock support
• All SPI pins broken out
• On-board 1.8V voltage regulator
• 1.8V level translation to any voltage between 1.8V-5V
• Bypass jumper
• PTH for VCCIO
• Bypass jumper to set VCCIO to VIN
• Silkscreen name change for input voltage (5V => VIN)
• Improved logic level translation on the Raspberry Pi side
