Building a LoRa receiver

In Figure 9.6, we see a LoRa receiver processing messages from our LoRa sensory transmitter. Our receiver design is straightforward, requiring only an LED to acknowledge received messages. We’re utilizing a Raspberry Pi Pico W for the receiver as we plan to leverage its Wi-Fi capabilities in the next chapter and publish sensory data to the internet.

We will not cover the steps to install CircuitPython or the required libraries onto the Pico W of the LoRa receiver as we covered these steps already for the LoRa sensory transmitter, and we merely need to do the same for the receiver. We should use the Pico W version of CircuitPython for this part of the project as we will implement Wi-Fi functionality in the next chapter.

Also, we won’t detail the construction of the custom case for the LoRa receiver as it mirrors the transmitter’s process. The key variation is fitting an LED with a resistor and LED holder in place of the DHT22 sensor...
