  • Page 3: Introduction

    1 Introduction This manual contains reference information for the CC2430 DB hardware. The following tools, which can be used with the kit, have their own user manual that can be downloaded from the TI website: ® SmartRF Studio Chipcon general packet sniffer IAR EW8051 C-compiler and C-Spy debugger (www.IAR.se) The CC2430DB demonstration board includes a number of functions and applications that allows quick testing of the RF interface and peripherals of the CC2430.

    Figure 2: Power switch setting The Power Switch S3 must be set according to what power source is used. If DC jack or USB power is applied, the switch should be set to the USB position. If the board is powered from batteries, the switch should be set to the BATT position as shown in Figure 2.

  • Page 6: Light Sensor

    5.7 Light sensor A light dependent resistor (LDR) measures light level and gives an analog signal that is measured by the CC2430 A/D converter. The light sensor resistance ranges from 5KΩ (light) to 20MΩ (dark). 5.8 I/O connectors The I/O connectors bring out all the signals from CC2430. These connectors allow easy access to all CC2430 I/O pins.

  • Page 8: P5 Jumpers

    The jumper between pin 3-4 can be removed when performing current measurement to reduce leakage current of the peripheral devices connected to the CC2430. The jumper must be mounted for normal operation The jumper between pin 5-6 can be mounted to perform accelerometer self test function. By mounting this jumper, a voltage is applied to the accelerometer outputs.

  • Page 9: Signal Flow

    5.10 Signal flow The signal lines from the I/O connectors and the CC2430 run via 0Ω resistors to the various peripherals on the CC2430DB. The peripherals can be disconnected from the CC2430 signal pins by removing the 0Ω resistors. Please refer to Table 6 for a list of what resistors correspond to which signals.

  • Page 10: Using Cc2430Db For Prototyping

    6 Using CC2430DB for prototyping The CC2430DB can be used for prototyping by programming the CC2430 with custom applications. All I/O ports on the CC2430 are available on pin row header at the edge of the board, and the USB interface can be used as In Circuit Emulator (ICE) interface allowing real time in circuit emulation of the CC2430.

  • Page 11: Low Power Operation

    6.3 Low power operation CC2430DB is designed for low power operation when running from batteries. Only the CC2430 is powered in this mode, the USB MCU is not powered. The voltage to the peripheral functions connected to the CC2430 is controlled by an I/O pin P1.2 (VDD_SW_CTRL) on the CC2430.
