125932-HMC675LC3C

Evaluation and demonstration boards and kits offer a platform to prototype, evaluate, and demonstrate a wide range of applications and devices. 125932-HMC675LC3C is one such development and evaluation board from RFmodule, which is ideal for developing systems that employ 802.11b/g/n wireless communications. It supports both host and client modes, allowing it to be used both as an application controller or as a wireless modem. The board is also FCC and CE compliant, which means that the system can be put to commercial use without any further approval.

Main Features

• 802.11b/g/n compliant
• Operates in dual mode - host or client
• Full control and regulation of MAC layer
• Support reception of all the currently available 2.4GHz frequency rates and channels
• FCC and CE compliant
• Supports up to 256 concurrent association devices

Application Field

The 125932-HMC675LC3C is suitable for many applications requiring direct, secure wireless communications over RF frequencies, such as smart home applications, intelligent health care systems, industrial instrumentation, Internet of Things (IoT) networks, and wireless sensor networks. It offers a simple and cost-effective way to embed wireless communication into any embedded system.

Working Principle

The 125932-HMC675LC3C evaluation board includes a RF module comprising a RF transceiver, an RF power amplifier, a microcontroller, and a board that controls the operating parameters of the transceiver and determines the functions of the module. This board communicates through the SPI interface with the controller, which can use its internal memory to store packet routing information, transmit data, receive data, and control the actual transceiver chip. It also provides a physical connection between the transceiver and the antenna, which is used for both transmission and reception.

In host mode, the board is used to control and manage the association devices that establish wireless communication. It can be used to manage power levels, transmit and receive data, and help with range and overall network communication. In client mode, the board is used as a slave device on an already existing network and can send or receive data.

Conclusion

The 125932-HMC675LC3C from RF Module is a great evaluation and demonstration board for developing, testing, and deploying wireless applications. It is easy to use, low cost, and FCC and CE compliant, making it suitable for both commercial and hobbyist deployments.
