Quantity   Component name
1 × Adafruit Feather LoRa M0 433Mhz Tracker - radio, microcontroller and charge/battery management
1 × Adafruit Ultimate GPS Featherwing Tracker - GPS position source and timing source for pseudo-TDMA
1 × 3.7v >1200mAh LiPo cell w/ JST connector. Tracker - power supply 1200mAh lasts around 24 hours with 20 second transmissions. Consider 1x18650@2200mAh
1 × 433Mhz 1/4 wave antenna - u.Fl Tracker - rubber duck antenna for tracker. Consider SMA-u.Fl to increase buying options
1 × u.Fl SMT Tracker - adds u.Fl connector to Feather LoRa M0 board
1 × 433Mhz mag mount antenna Base Station - reception antenna - magmount makes it easy to take down and install but you might consider a tall pole with 5 element colinear for better range
1 × Raspberry Pi 3 Base Station - map server, WiFi access point
1 × Uputronics Hoperf RFM98 expansion board Base Station LoRa reception. Could use a bare RFM98 module for cost, but this is neat. https://store.uputronics.com/index.php?route=product/product&path=61&product_id=68
1 × UPSPico Raspberry Pi UPS (was MoPi power unit, but can't do desired UPS functions)
1 × DS3231 RTC module Base Station Real-time clock source to set time on Pi at boot - otherwise position reports are wrong. Could use mobile device to set time but this works fine. https://thepihut.com/blogs/raspberry-pi-tutorials/17209332-adding-a-real-time-clock-to-your-raspberry-pi
