This time we get hands-on: flashing three nodes with the Meshtastic firmware, configuring them through the phone app, and sending our first broadcast, direct, and encrypted channel messages.
In this first part, I want to cover what LoRa is, how mesh networking works, and how the two protocols differ, along with the hardware I will use for the rest of the series.
The SparkFun Pi Servo pHAT provides your Raspberry Pi with 16 PWM channels that can be controlled over I2C. These channels are broken out in a header combination that is perfect for connecting servo motors.
