## KNOWN UART ##
################
UART HEADER: is a 4 pin header in the back of the router behind the metal heatsink
PIN 1: Is marked by silkscreened hollow triangle
Pin 1: If facing router, with ports & lights in front of you, pin 1 is on the left.
Pin FUNCTION
1 VCC (3.3v constant)
2 GND (continuity to DC negative)
3 TX (3.3v high, fluctuating during transmission, dead when unpowered)
4 RX (3.3v high, fluctuating during transmission, dead when unpowered)
