I did a basic schematic of the four sensor that I will be testing with the Adafruit Feather 32u4 LoRa. I'm using EasyEDA since it is cloud based and therefor really convenient when working from multiple computers. I have the GPS and IMU already, and I'm currently getting to grips with interfacing them with the Feather. Still waiting for the pulse sensor and RTD probe and amp breakout.
