A: No. This is the debugging/evaluation carrier board only. The HLK-LD6001 or HLK-LD6002C radar module must be purchased separately and inserted into the board's header connector. Q: Which radar modules are compatible with this board? A: The board is designed for Hi-Link's 60GHz series including HLK-LD6001 and HLK-LD6002C. Check pin mapping before using other modules from the HLK-LD series. Q: What software do I use to configure the radar? A: Hi-Link provides a free Windows PC configuration tool (HLK Radar Config). You can also use any serial terminal at 115200 baud and send UART protocol commands documented in the module's datasheet. Q: What is the difference between HLK-LD6001 and HLK-LD6002C? A: The LD6001 is the base human presence and motion detection module. The LD6002C adds fall detection capability and outputs more detailed motion data. Both work with this debugging board. Q: Can I connect the board to an Arduino or Raspberry Pi? A: Yes. Use the UART header pins (TX, RX, 3.3V, GND) on the board to connect directly to your MCU or SBC. The onboard CH340 is only needed for USB/PC connection. Q: What data does the radar output? A: Over UART, the module outputs presence/absence flags, motion intensity, range estimates, and (for LD6002C) fall detection events. The exact protocol is detailed in the Hi-Link module datasheet. Q: Does it work through walls or furniture? A: 60GHz mmWave radar can penetrate thin non-metallic materials such as plastic enclosures, but not concrete walls or metal surfaces. It is optimized for detection within a room. Q: What is the detection range? A: The HLK-LD6001 and LD6002C support up to 8m range detection with ±60° horizontal and ±30° vertical coverage. Detection distance varies with sensitivity settings and target size. Q: How does 60GHz radar compare to PIR sensors? A: 60GHz FMCW radar can detect stationary humans (micro-motions like breathing), works in complete darkness, and is not affected by temperature changes. PIR only detects moving objects and can false-trigger from heat sources. Q: Can this board be powered without a USB connection? A: Yes. The board can be powered via the 5V pin header if USB is not convenient. Provide 5V from your system power rail to the VCC header pin.
