1 Antenna

0 SMA connector

0x15 Cal OSC 16 MHz uint8 RF231 XTAL calibration value, register

“XTAL_TRIM”

0x16 Cal RC 3.6 V uint8 AVR internal RC oscillator calibration value

@ 3.6 V, register “OSCCAL”

0x17 Cal RC 2.0 V uint8 AVR internal RC oscillator calibration value

@ 2.0 V, register “OSCCAL”

0x18 Antenna Gain int8 Antenna gain [resolution 1/10 dBi]

eg.: 0x0A = 10d will indicate a gain of 1.0dBi.
