JAE JRE-30 Radar¶
The JAE (Japan Aviation Electronics Industry) JRE-30 radar is a light weight (110g) radar with a maximum range of over 50m. The relatively wide beam width (about 20 deg) and reliable ranging even in difficult environments can make it a better choice than lidar for some applications.
The sensor supports both CAN and Serial interfaces.
Where to Buy¶
The JAE JRE-30 radar can be purchased directly from JAE. Note that it is only certified for use in Japan.

If you choose to build a custom cable BPH-002T-PO.5S socket connectors should be used.
Setup using Serial¶
Set the following parameters which assume the radar is connected to the autopilot’s Serial1 port
Set SERIAL1_PROTOCOL = 9 (Rangefinders)
Set SERIAL1_BAUD = 460 (460800 Baud)
Set RNGFND1_TYPE = 41 (JRE Serial)
Set RNGFND1_MIN_CM = 10 (cm)
Set RNGFND1_MAX_CM = 5000 (cm)
Setup using CAN¶
Set the following parameters which assume the radar is connected to the autopilot’s CAN1 port
Set CAN_P1_DRIVER = 1 (First Driver)
Set CAN_P1_BITRATE = 1000000 (1 Mbps)
Set CAN_D1_PROTOCOL = 1 (DroneCAN)
Set RNGFND1_TYPE = 24 (DroneCAN)
Set RNGFND1_MIN_CM = 10 (cm)
Set RNGFND1_MAX_CM = 5000 (cm)
Set RNGFND1_ADDR = 1
