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.      Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
