Trimble TK42RF User Manual

TI RF AMP Module Integration Manual

This module will be built in only in Trimble products by Trimble itself. Trimble makes sure that the
maximum voltage is 3.8V.

The design is based on the CC2520 from Texas Instruments.

• VDD: supply voltage 1.8 - 3.8V

• GND

• SPI_OUT: SPI Interface Serial Out

• SPI_IN: SPI Interface Serial In

• SPI_CLK: SPI Interface Serial clock 8MHz max

• CS_N: SPI Interface Chip select active low

• RESET_N: External Reset pin active low

• VREG_EN: when High, digital voltage regulator is active

• GPIO0: general purpose digital I/O

• GPIO1: general purpose digital I/O

Mounting instruction:

The module could be mounted and connected like a SMD_component.

Maximum Voltage: 3,8V

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

running the module.
