5. RF-EB

The RF-EB is an evaluation board for demonstrating the main features of CMOSTEK NextGenRF

TM

products and allowing the user to develop their own applications.

The module can be used with the evaluation modules in Evaluation Scheme (see

Chapter 2 for details).

The main components are shown in Figure 6 below:

5.1 Main Components

1.

EM-Connector –The EM-Connector is 10-pin, 2.54 mm female connector which connects the RF-EB to the evaluation modules.

2.

LED – There are 3 LEDs available to indicate the working status of the RF-EB.



LED1 indicates that the RF-EB received 1 frame successfully when working with CMOSTEK Rx products.



LED2 indicates that the RF-EB transmitted 1 frame out successfully when working with CMOSTEK Tx products.



LED3 is reserved for future use.

3.

Power Mode Jumper – The power mode jumper (J7) determines the power supply source of the RF-EB. The board can be supplied by the USB (J7 switched to the USB side) or the batteries (J7 switched to the BAT side).

4.

Power Switch – The power switch (SW1) allows the user to turn the RF-EB power on or off. It is recommended that the user shall power off the RF-EB before plugging in or out the CMT2110A-EM.

5.

USB Socket

– A USB (type B) socket is used on the RF-EB. A USB cable is provided in the Development Kits for the user to connect the RF-EB to the PC. The USB connection is for power supply only, not for data communication.

6.

LCD

– A 128*64 pixels LCD is available on the RF-EB to display the information for the configuration and demonstration
