CC2511 Dongle

8.3Debug connector

The CC2511 Dongle has debug connector (P3) that is compatible with the SoC debug connector on the SmartRF04EB. This enables the CC2511 Dongle to be programmed and debugged via the SmartRF04EB. The debug connector and the test pins on the CC2511 Dongle can be removed to reduce its size. If that is done, programming and debugging can still be done using the connector on the back of the CC2511 Dongle (P5). The pin-out of the debug connector (P3) is given in Table 2.

8.4General purpose I/O connectors

All GPIO pins on the CC2511 that are not used on the Dongle are routed to the P4 “Test pins” pin-row. They can be used for debugging or to connect external devices to the CC2511. The pin-out is given in Table 3.

8.5Cutaway section

On the CC2511 Dongle the debug connector and the GPIO test-pin connector is mounted on a section of the Dongle that may be removed to minimise the CC2511 Dongle size. This cutaway section is marked with a white line, see Figure 11. If this section is removed from the dongle, the CC2511 can still be programmed and debugged using the alternative debug connector found on the back of the CC2511 Dongle, see Figure 12.

8.6RF Performance of PCB antenna

The performance of the PCB antenna will be affected by the device the CC2511 USB dongle is connected to. Thus, when plugged into different computers or a USB extension cable differences in the CC2511 USB dongle RF performance must be expected. The maximum antenna gain measured with this design is 5.3 dBi. Thus, duty cycling or reduction of output power might be needed to ensure compliance with regulatory limits, see application note AN032 for more information about SRD regulations in the 2.4 GHz ISM band. AN032 is available from www.ti.com/lpw or www.chipcon.com.
