Product Description

This product is our RFM22B breakout board, for the RFM22B RF transceiver modules from HopeRF. The RFM22B breakout board gives you access to all the pins on the RFM22B module in a through hole format so that it is easy to use in a prototyping environment. The antenna connection is a convenient SMA connector so you can attach anything from a stub antenna up to a yagi for superior range (we have been able to communicate over many km’s using these modules with good antennas).

These RFM22B breakout boards come with the RFM22B module pre-installed, so all you have to do is attach the breakout board to your project and you’ll be up and running!!

The HopeRF RFM22B is a low cost, highly integrated, 433, 868 & 915MHZ wireless ISM transceiver module (frequency depends on the product selected). The low receiver sensitivity (–121dBm) coupled with industry leading +20dBm output power ensures extended range and improved link performance. These modules can communicate of many, many km’s depending on the data rate and RF environment  Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance. The wide operating voltage range of 1.8–3.6 V and low current consumption makes the RFM22B an ideal solution for battery powered applications.

Communication with the RFM22B module uses a standard 4-wire SPI interface. Three configurable general purpose I/Os are also available, the use of which can be tailored for the needs of your project or solution. The RFM22B also incorporates a range of other features, including an 8-bit ADC, temperature sensor, RX and TX FIFOs, and low-battery detection. A datasheet for this product is available below (manufacturer provided)

The breakout board comes in a 14pin DIP compatible module, with pins spaced at 2.54mm (suitable for breadboard use) and uses an SMA connector for the antenna.

    :

    Excellent product, we’re using some of these at my local Maker Space along with the nanoTRONCIS24 dev board. They are working really well for us and they appear to be a quality product.

    Our only complaint is that we want to buy some more to extend our network, but we’d like to be able to buy them with nanoTRONICS24 boards as a kit. Is this something you’d consider offering?

    :

    Thanks for the feedback – we’ve added nanoTRONCIS24 kits as an new option. You can now order the nanoTRONCIS24 in any of the following combinations:

    - Standard nanoTRONICS24 development board
    - nanoTRONICS24 development board with LCD
    - nanoTRONICS24 development board with 433MHz RFM22B Breakout Board
    - nanoTRONICS24 development board with LCD and 433MHz RFM22B Breakout Board

    If you wish to order any of these kits you’ll find them on the nanoTROINCS24 product page: http://modtronicsaustralia.com/shop/nanotronics24-pic24-development-kit-board-usb-rfm22b-lcd/

    We hope that you’ll find this to be a useful addition.

    Thanks,

    Modtronics Australia Team
