At the end of February, Raspberry Pi launched Raspberry Pi Zero W. This is the first Raspberry Pi that offers Wi-Fi connectivity on their boards. The Raspberry Pi Zero W is an updated version of the original Raspberry Pi Zero v1.3, with a wireless chip that supports 802.11b/g/n Wi-Fi (2.4GHz) and Bluetooth 4.0. At 2.6″ x 1.2″ x 0.2″, the Pi Zero W has the same dimensions as the original but weighs a little more due to the extra chip.
The Pi Zero W has the same radio chip as the Raspberry Pi 3, but has an antenna that has been printed into the board. The antenna is licensed technology from Swedish company Proant. Roger Thornton, principal hardware engineer, says, it is “a resonant cavity which is formed by etching away copper on each layer of the PCB structure.” This means radio waves resonate in the cavity at the right frequency. The Pi Zero W comes with a case with interchangeable lids, sold separately, that have holes for ports, pins and a ribbon connector for the camera.
