Set-up
The sensor already has the firmware pre-loaded onto the XM132 and ATmega. Loaded onto the ATmega is a small program which enables power on the XM132. The XM132 has the Acconeer XM132 Module Software version 2.8.2 available on the Acconeer developer website. We recommend using the Acconeer portable exploration tool available here to interface the sensor with a computer via rapid prototyping.
To connect the sensor please wire up the 3V3, GND, RX2, TX2 from the radar sensor to the USB-TTL converter as per the wiring table below. Leave all other wires disconnected. Open up the Acconeer portable exploration tool and select the serial port attached to the XM132. Click connect. The radar sensor should now interface with the software. If not, double check the wiring between the USB-TTL converter and the radar sensor, sometimes RX and TX are labeled opposite to what is expected, so try swap these pins around. The Acconeer portable exploration tool must be restarted before to reattempt the connection.
Wiring
To connect the sensor to a USB-TTL converter please follow the wiring diagram below:
| USB-TTL | Radar Sensor |
|---|---|
| 3.3 V | Green |
| GND | Grey |
| reset | Orange |
| wake | White |
| TX (ATmega) | Yellow |
| RX (ATmega) | Blue |
| TX2 (XM132) | Purple |
| RX2 (XM132) | Black |
Radar Lens
The provided radar lens is removable. To remove the radar lens insert the supplied lens removal tool onto the face of the lens. The tool should key into the lens when properly inserted. Turn the tool counter-clockwise to unscrew the lens. Follows these instructions in reverse to re-attach the lens.
