RS Components adds two new wireless connectivity options to its portfolio

RS Components, trading brand of Electrocomponents plc, has added two wireless connectivity options to its portfolio of products based on the Raspberry Pi computer.

Built using Wi-Fi and low power radio technology, the new modules deliver wireless interface capability for applications requiring low cost, low power, small form factor solutions, such as mobile devices.

The frist module is a wireless nano USB adapter from Edimax, which provides high-speed Wi-Fi functionality compliant with the IEEE802.11b/g/n wireless protocol via a tiny adapter that plugs into the USB port on the Raspberry Pi. It supports transmission rates of up to 150Mbps, adjusting the transmission output according to the distance and CPU offload to achieve a reduction in power consumption of between 20% and 50% when the wireless function is idle.

The second module is Connect2Pi from LPRS, which also features a USB wireless device offering 'plug-and-play' connection to the Raspberry Pi, but instead uses low power RF transceiver technology to provide a bi-directional link to any device supporting serial communications.

The device allows users to configurate frequency, bandwidth, power output and data rates, so that multiple devices can communicate free from interference from each other and any other RF devices.

The RF technology enables greater range (up to 200m depending on the terrain) and lower power consumption than other wireless protocols such as Wi-Fi or Bluetooth. The host device can send and receive up to 180 Bytes of data per packet to other hosts within range, making it particularly useful for 'sense and control' applications.

The module comes in wo versions, of 433MHz and 868MHz, and an integral SMA antenna is included.
