2. Disclaimer Typical values contained in this application note are based on simulations and testing of individual examples. Any information about third-party materials or parts was included in this document for convenience. The vendor may have changed the information that has been published. Check the individual vendor information for the latest changes. 3. Overview The REB233CBB Module is a compact solution providing wireless connectivity between IEEE 802.15.4/ZigBee compliant devices.
5. Functional description The block diagram of the REB233CBB Module is shown in Figure 5-1. The Radio PCB and Microcontroller PCB are connected via a mounting header. The Radio PCB is not functional without connecting it correctly to the Microcontroller PCB. The Radio PCB is equipped with two approved antennas; see B.3 and [2], to enable antenna diversity (AD) operation.The Microcontroller PCB controls the Radio PCB, provides the power supply as well as the user interface.
.2 Radio PCB The Radio PCB carries the radio transceiver AT86RF233 [3]. The radio transceiver is a high performance RF-CMOS 2.4GHz radio transceiver targeted for IEEE802.15.4, ZigBee, RF4CE, 6LoWPAN, and ISM applications. The identification EEPROM carries Radio PCB information used by the Microcontroller PCB. 5.3 Antennas The antennas intended for the REB233CBB Module, see B.3 and [2], are to be connected to the SMA connectors on the Radio PCB.

PC connectivity can be easily achieved by using a serial to USB level shifter stick [8] as shown in Figure 5-3. Figure 5-3. USB level shifter stick. 5.
Address Name Type Description 0x18 Antenna gain Int8 Antenna gain [resolution 1/10dBi]. For example, 15 will indicate a gain of 1.5dBi. The values 00h and FFh are per definition invalid. Zero or -0.1dBi has to be indicated as 01h or FEh 0x20 Board name Char[30] Textual board description 0x3E CRC Uint16 16-bit CRC checksum, standard ITU-T generator polynomial G16(x) = x 12 5 +x +x +1 16 Note: MAC addresses used for this product are Atmel property.
7. Firmware description 7.1 Range measurement The REB233CBB Module is pre-flashed with the RF performance test suite featuring a range measurement application. Each module operates in a standalone manner, and is able to transmit or receive data frames. A successful transmit or receive operation is indicated by a blinking LED. 7.1.1 Power up the modules Apply power to both modules by switching on the power switch.
7.2.2 Driver installation Download the USB adapter drivers from http://www.dresden-elektronik.de/shop/prod152.html?language=en, ‘Downloads’ tab and extract the archive to a folder of your selection. If the ‘New Hardware Found’ wizard prompts for drivers ignore Windows® update search (‘No, not this time’). In the next dialog, select ‘Install from a list or a specific location’ and point at the extraction directory.
8. Electrical characteristics 8.1 Absolute maximum ratings Stresses beyond the values listed in Table 8-1 may cause permanent damage to the board. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this manual are not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
