Constructing a Raspberry Pi RP2040 Low-Power Sensor Node – Day 4
There is absolutely nothing wrong with stringing wires to our RP2040 sensor node. However, Kirk and Spock didn’t do that on TV and don’t count on us doing that here either. There are too many LoRa, 900MHz, Wi-Fi, and 2.4MHz wireless solutions we can pick from. We won’t stoop to planting a garage door opener radio on our sensor node, but we will take a look at some other suitable data radio modules that operate in the ISM band.
