For Zero/Zero 2W to 3B, Banana Pi -M2 Zero to 3B expansion board, zero USB HUB and Ethernet expansion board,This adapter board can perfectly convert the zero to the 3B shape structure,At the same time, if you are using Zero 2W, because the zero 2W main control CPU is the same model as the 3B, it can be perfectly compatible.With design, you can make your Zero using the same USB/-compatible/RJ45 ports.The height of the 20x2 GPIO Pins will not change. Perfect use of GPIO expansion boards.Interface IntroductionOnboard USB expansion port, compatible with USB 2.0/1.1 transmissionOnboard RTL8152B Ethernet chip, supports 1 RJ45 network port, 10/100M -adaptiveCan be installed directly to Zero/Zero W/Zero WH and Banana Pi M2 Zero, through jumper test, can be connected to other versions of , Banana Pi or general computer or Android phone through usb cable3USB+RJ45 expansion board: 3 USB ports, with RJ45 Ethernet portMaterial: PCBcolour: greenPackage Contents:1 x 3USB Expansion BoardOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
