The HF-A21 module is a compact high performance WiFi module providing 802.11b/g/n 2.4 GHz WiFi networking for a printed circuit board device design. With a rich feature set and an industrial temperature range, this surface mount embedded module is well suited for many applications even in harsh environments. A small footprint makes the HF-A21 easy to use in handheld devices.

Available with 2 antenna options, the HF-A21 module provides design flexibility to meet specific application requirements or can be used in existing device designs.

The interface with the HF-A21 is via 10/100 Ethernet and high speed UART. Using either the user-friendly web page or an AT+ instruction set, this module is easy to configure. The HF-A21 can operate in Infrastructure Station (STA) mode, Soft Access Point (AP) mode or AP+STA mode. Support for Ethernet-to-WiFi Router/Bridge mode networking is also provided.

The High-Flying A11 modules are design for high performance applications normally, using 802.11b/g/n, Ethernet, and local serial ports. The A11 is available in two formats – SMT (surface mount) and DIP (2x7pins). A11 integrates an Ethernet and Wireless MAC, a baseband processor, a RF transceiver along with a power amplifier. The on-board software includes a complete Wi-Fi protocol, configuration utility and networking stack. Applications include access points, routers, serial to Ethernet, serial to Wi-Fi, Ethernet to Wi-Fi bridging and many others.gc-hf-a11_1_1The A11 integrates all Wi-Fi functionality into a low-profile SMT or DIP module package that can be easily mounted on a printed circuit board. The different A11 modules connect to antennas using the local chip antenna (INT), external antennas through the standard IPEX/U.FL connector, or directly through the on-board SMA connectors.

Features:

  • Serial UART, Ethernet, Wi-Fi 802.11b/g/n applications
  • WEP / WPA / WPA2 security modes
  • Low Cost High Performance MCU

10 Internet of Things (IoT) Design Considerations: Power and Size

5. Power

Power considerations need to be made when connecting a product to the IoT. Products already using a wall outlet will not have an issue. Manufacturers of products not using a wall outlet will have to consider how their power source will affect their product’s design.

IoT devices running on batteries will have to make hardware decisions based on power conservation. There are also a variety of different types of batteries to be taken into consideration: alkaline, lithium (rechargeable) and coin. There are also AA, AAA, coin cell, C, D, 9V, or custom batteries to choose from. As noted earlier, wireless technologies have different power requirements based on use-cases. Once a manufacturer understands how long and how often a device will be connected and the wireless network is chosen, a properly sized and type of battery can be chosen.

Another source of power for Ethernet-based devices is Power-over-Ethernet (PoE). This technology is popular for low-wattage IP phones and security cameras. Recent advancements and new switching technology is pushing the wattage available through PoE to new levels, thus opening up new possibilities for more power-hungry applications and devices.

6. Size

Many manufacturers start testing the IoT waters by modifying their existing product designs to add networking technologies. Because these devices already exist, many early entrants into the IoT world fail to redesign the product to allow for its newly added connectivity. Fortunately, there are a number of compact modules available for networking technologies that will fit in a manufacturer’s existing products.

These small modules are different though. Some modules are surface mount, others through-hole or pin-header and some still use a specialized mating connector. Also, how the network connector or antenna connector are integrated into the product vary from module to module. Designers must consider the space they have available on their circuit boards and/or in the product’s enclosures to allow whatever technology selected to be used in existing designs.
