Description This is the smallest Raspberry Pi available at the moment, now with the GPIO-header presoldered. The board is just half the size of a Raspberry Pi Model A+, but with more capabilities! The Raspberry Pi Zero W features wireless connectivity providing onboard Bluetooth 4.1, BLE and WiFi! The board itself is just 65mm x 30mm x 5mm in size, is has a mini camera connector, a microSD slot, mini HDMI, 2x microUSB (one for USB and one for Power). Just like the A+ and the B+, the Pi Zero W features a single core CPU clocked at 1GHz and 512MB RAM. The GPIO header is presoldered so you can start right away with your projects! Features BCM2835 (same as the Pi 1) but clocked at 1GHz (40% faster) 512MB RAM 802.11 b/g/n Wireless LAN Bluetooth 4.1 Bluetooth Low Energy (BLE) microSD Slot mini HDMI connector microUSB for data microUSB for power mini Camera connector (camera adapter cable needed) Pre-soldered 40-pin GPIO header (same pinout as other Pi's) Dimensions are 65mm x 30mm x 5mm
