* map system (automatically load open source)
* separate fully from view1090 (which interface?)
###HARDWARE ###HARDWARE
Notes:
Pi 3b+ and below are a little underpowerd for unoptimized map drawing
Pi 4 is smooth, may have USB issues with RTLSDR?
Up squared is good, but large
Up Core may be fine but bad connection options - try up core?
PiJuice is by far best battery option. FCC/CE certified!
Need to test stratux low power dongles. 987Mhz?
Waveshare 4.3" HDMI(B) is very good, slightly too large for handheld. Uses a lot of power, around 500ma
Pimoroni Hyperpixel 4.0 is the right size, but takes over default I2C pins so conflicts with PiJuice, unless some pin remapping. Also lower power, around 150ma
Adafruit PiTFT 2.8" capacitive touch is ok, but a little small. Not sure about power draw. Docs claim no multitouch?
