for Raspberry Pi Zero WH with 40 PIN Pre-Soldered GPIO Headers with WIFI and Bluetooth in Demo Broad 1GHz CPU With all of the features we know and love of Raspberry Pi Zero W; the new Raspberry Pi Zero WH is the same board that also includes professionally 40 PIN soldered headers. The difference between this edition and the current Pi Zero W is its pre-soldered GPIO header. This makes it much easier to start prototyping with a Pi Zero board, because you no longer need to solder pins to the header manually.It's perfect for everyone who doesn't own a soldering iron or who wants the soldering legwork done for them. There are many instances where you do want a header on your Zero W, for example in order to easily take advantage of the GPIO expander tool for Debian Stretch on a PC or Mac. Using the GPIO expander with the Raspberry Pi Zero WH decreases the setup cost for anyone interested in trying out physical computing in the classroom or at home. for Raspberry Pi Zero WH Features: BCM2835 512MB RAM Mini-HDMI port (1080p60 video output) 1GHz ARM11 single-core processor 40PIN pre-soldered GPIO headers Composite video and reset headers CSI camera connector Added wireless connectivity 802.11b/g/n wireless LAM Bluetooth 4.1 Bluetooth Low Energy (BLE) Micro-USB OTG port Micro-USB power Micro-SD card slot Dimension: 65mm x 30mm x 11.6mm colour:green Material:plastic Package Contents: 1 x Raspberry Pi Zero WH 1 x 40 PIN pre-soldered GPIO Headers Only the above package content, other products are not included.
