RS Components (RS) has added two wireless connectivity options to its growing portfolio of products based on the Raspberry Pi computer.

The first module is a wireless nano USB adapter from Edimax, while the second module is Connect2Pi from LPRS. Built using Wi-Fi and low power radio technology respectively, the two new modules deliver wireless interface capability for applications requiring low cost, low power, small form factor solutions, such as mobile devices.

The wireless nano USB adapter from Edimax 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. The adapter supports transmission rates of up to 150Mbps, which is ideal for large data transfer and three times faster than standard 11g connections. The smart adapter adjusts 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. It can be configured using Wi-Fi Protected Setup (WPS) to provide a simple, secure wireless network.

Connect2Pi from LPRS also features a USB wireless device offering 'plug-and-play' connection to the Raspberry Pi. However, this module uses low power RF transceiver technology to provide a bi-directional link to any device supporting serial communications, for example another Raspberry Pi. Frequency, bandwidth, power output and data rates can be configured to allow multiple devices to communicate free from interference from each other and any other RF devices. 

The RF technology employed enables significantly 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 Connect2Pi module is available in 433MHz and 868MHz versions along with an integral SMA antenna. A kit variant of this product, which contains dual rather than a single transceiver, is also available.

All three Raspberry Pi wireless products are available from RS stock for same-day despatch.
