Review on 🔌 Complete 38 Modules Sensor Kit for Raspberry Pi - KINCREA KUMAN K5: Ideal for RPi 3, 2 Model B B+ A A+! by Mike Woolford

They are compatible with Arduino projects that use I2C displays and other I2C devices, unlike many similar shielded versions of this transceiver. I didn't find anything wrong with them. Radio. I unplugged unshielded devices, plugged them in, turned on the backup power and enjoyed a better connection. However, I felt the need to use higher gain antennas from unshielded devices to feel like I was getting the best out of them. On the test track, I found reliable communication up to several hundred meters through fairly dense forest and more. open line of sight. I've tried both the included 2.1dBi and higher antennas (no gain markings). Longer, higher-gain antennas provided significantly greater range.
