Wi-Fi and Bluetooth bring wireless connectivity to Raspberry Pi 3 Model B+ IoT SBC

Wireless connectivity is accessible to the Raspberry Pi 3 Model B+ Internet of Things (IoT) single board computer (SBC), says Cypress Semiconductor, as it announces its Wi-Fi and Bluetooth combination for the board.

The Cypress CYW43455 provides 802.11ac Wi-Fi for faster internet connections, advanced co-existence algorithms for simultaneous Bluetooth and Bluetooth Low Energy (BLE) operations such as audio and video streaming, and low-power BLE connections to smartphones, sensors and Bluetooth Mesh networks.

The high-speed 802.11ac transmissions enable faster downloads and better range, as well as lower power consumption using deep sleep modes. The CYW43455 SoC features a dual-band 2.4- and 5.0-GHz radio with 20-, 40- and 80-MHz channels with up to 433Mbit per second performance. Fast 802.11ac throughput allows devices to get on and off of the network more quickly, preventing network congestion and prolonging battery life by letting devices spend more time in deep sleep modes. 

Wi-Fi networks powered by 802.11ac simultaneously deliver low-latency and high-speed with secure device authentication, making it suitable for connecting products directly to the cloud. The Raspberry Pi 3 Model B+ board with the integrated Cypress CYW43455 SoC allows developers to quickly prototype industrial IoT systems and smart home products that leverage 802.11ac.

Eben Upton, CEO of Raspberry Pi Trading says: “Our new board democratises high-performance, interoperable and highly reliable 802.11ac Wi-Fi for use across a huge range of IoT products.”

The Raspberry Pi 3 Model B+ board features a 64-bit, quad-core processor running at 1.4GHz, 1Gbyte RAM, full size HDMI and four standard USB ports, Gigabit Ethernet over USB2, Power over Ethernet (PoE) capability, CSI camera connector and a DSI display connector. The platform’s resources, together with its 802.11ac wireless LAN and Bluetooth/BLE wireless connectivity, provide a compact solution for the intelligent edge of connected devices, says Cypress.

The SoC includes Linux open source Full Media Access Control (FMAC) driver support with enterprise and industrial features enabled, including security, roaming, voice and locationing.

The SoC is also supported in Cypress’ Wireless Internet Connectivity for Embedded Devices (WICED) software development kit (SDK).
