AMW106-A02 Application Field and Working Principle

The AMW106-A02 is an evaluation board that provides basic integration of the AMW106-A02 daughter card, enabling quick and easy evaluation of the digital features of the device and the board. This board is a multi-chip evaluation platform for the AMW106-A02, featuring single- and multi-channel WLAN, Bluetooth, Zigbee, ISM and 802.11n Wi-Fi. It is a building tool for embedded design prototyping and testing, and is ideal for designers who want to quickly create an embedded wireless device with the AMW106-A02. It also provides a low-cost development platform for users looking to evaluate their own applications and testing.

The AMW106-A02 includes a controller, analog base band layer, PHY layer and RF transceivers. The controller is based on the Ralink Wi-Fi RT5350 processor, a synthesizable, single-chip 16-bit microcontroller. It also includes a 64KB SRAM. The analog baseband layer is based on a single, low-power direct conversion receiver (DCR) for use in the 2.4GHz ISM band. This is connected through a set of two RF transceivers which can be connected to the antenna to operate in either single- or multi-channel environments to increase the radio signal coverage.

The AMW106-A02 board\'s features for highly integrated wireless signal transmission and reception include:

• 802.11b/g/n wireless LAN
• Bluetooth
• ZigBee
• ISM 2.4GHz band
• RF transceiver for low power application
• Power-saving functions

The AMW106-A02 board is primarily used for wireless development and communication. The board has two radio modules, Wi-Fi module and the Bluetooth module. With the Wi-Fi module, users can access and control the web server or IO devices locally using IEEE 802.11b/g/n. The Bluetooth module allows users to embed a BLE radio and monitor connections. The ZigBee module allows users to bridge two networks and route data. The ISM module enables users to have a cloud-based wireless access to the Internet. Furthermore, the board supports power-saving features such as low power internal active and sleep modes. It supports the standard UART, JTAG, SPI, I2C, USB, NFC, and SD interfaces.

The board\'s working principle is circular; it uses the transceiver\'s RF receiving ability to simultaneously receive data from different areas and then the controller makes decisions on how the data should be processed. The transceiver then sends the data to a designated destination. The Main Controller is responsible for decision making and other processes on board. It controls the on-board peripherals, such as Ethernet ports, GPIOs, and RS232. It also stores all program flow control and monitoring information. The analogue baseband layer is responsible for the signal processing for the incoming and outgoing digital RF signals. This layer includes the direct conversion receiver and low noise amplifiers.

Overall, the AMW106-A02 evaluation board provides designers and engineers with a low-cost, low-power and easy to design platform that helps them quickly evaluate and develop their own embedded device that takes full advantage of the AMW106-A02 daughter card integrated. With the added features of the two-radio modules, Wi-Fi module, Bluetooth module, ZigBee module and ISM module, users can quickly set up a cloud-based wireless network that is secure and reliable.
