The module power supply voltage range is DC 3.0
～
3.6V, above DC 3.6V, the module will damage. It is
recommended work at DC 3.3 V.

．
The module interface use double row headers to connect with mother board. The GND pin must connect to
the system ground.

CC1110’s pin P0.6 and P0.7 are used as power amplifier switch control. The right voltage level is:
RX mode: RE=0

TE=0
（
Low

Except the TX mode you have to set the PA control voltage at TX mode, the PA control pins should be set at RX
mode to get a low power consumption.

C, and CC1110’s pin P2.1 and P2.2 are used as
EEPROM’s clock(SCL) pin and data(SDA) pin. These two pins are also debug pins, so the EEPROM doesn’t
support IAR.
If you purchase the module integrated EEPROM, we will provide the read/write code.

CC1110 integrated 8051 microcontroller core support IAR, the debugging interface include clock pin
P2.2(DCLK) and data pin(DDA), you can connect these two pins to the simulator interface on the programming,
detail information refer to CC1110 datasheet.
