(1) These signals are test UART signals which are 1.8v logic, and they should be left unconnected for normal operation.
(2) The I2C data signals from the CC3000 and EEPROM must be connected together for normal operation.
(3) The I2C clock signals from the CC3000 and EEPROM must be connected together for normal operation.
(4) The antenna terminal presents a DC short circuit to ground.
PI = Power Input
