The design is based on the CC2520 from Texas Instruments.

• P1: Vdd supply voltage 1.8 - 3.8V

• P2: GND

• P3: SO SPI Interface Serial Out

• P4: SI SPI Interface Serial In

• P5: SPI_CLK SPI Interface Serial clock 8MHz max

• P6: CS_N SPI Interface Chip select active low

• P7: External Reset pin active low

• P8: Vreg_EN when High, digital voltage regulator is active

• P9: GPIO0 general purpose digital I/O

• P10: GPIO1 general purpose digital I/O

Mounting instruction:

The module could be mounted and connected with a plug connector or could be mounted on a

plastic holder and connected with cable (P1-P10).

Maximum Voltage: 3,8V

Connect the SPI Port to a microcontroller and use the instruction of Texas Instruments to start

running the module.
