I built a LoRa-GPS Tracker // Range test, battery life & firmware

#lora #gps #eink

I built my LoRa-GPS Tracker with PCBs from PCBWay https://www.pcbway.com. I worked on the firmware and ran some tests before doing an outdoor range test. Here, I describe each of the components of building the device.
