Production Unit Development Overview

This is a document recording notes for the path to creating a working production unit.

Hardware

Get SIM5320A GPRS/GPS working
- Need to automatically start and connect on boot
- Need to confirm GPRS antennae and GPS antennae work inside or at other positions in housing
- GPRS needs to have some pin tied for automatic power on (potentially rpi controlled)
Connect/stack SIM5320A in line with screen
- make sure screen and serial have no physical pin conflicts
Make breakout board for power connector
Find solution for speaker amplifier
Need to figure out case. Stop-gap of retrofitting to current case
- New case need only to attach to the four screw configuration already in place for DIU bottom plate
Look into brighter screen
