Expansion card features:1. Using a unique adapter design, direct insertion, a strong sense of .2. At the same time, the zero -compatible port is converted into a 3B universal female port, which is convenient to use.3. At the same time, the GPIO height position perfectly inherits the GPIO height of 3B and zero, so that customers who need to insert GPIO expansion boards can insert perfectly without changing the height.Interface Introduction: 1. Onboard 4-way USB expansion port, compatible with USB 2.0/1.1 transmission. 2. Onboard RTL8152B Ethernet chip, support 1 RJ45 network port, 10/100M adaptive. 3. It can be directly installed to for Zero/Zero W/Zero WH and Banana Pi M2 Zero, through the jumper test, it can be connected to other versions for , Banana Pi or general computer or Android mobile phone through the usb cableDevelopment board specifications:Module: for Banana Pi -M2 ZeroCPU: H3+ -core -A7 H265/HEVC 1080PGPU: Mali400MP2 GPU @600MHz, Supports OpenGL ES 2.0Memory (SDRAM): 512M DDR3 (shared with GPU)Onboard Storage: TF card (Max. 64GB)Onboard Network: ( can extension with PIN define)PoE power: Onboard flash: Onboard WIFI: SDIO AP6212 (option AP6181, AP6335)Video decoding: 1080p@60fps, 264 Video encoding 1080p@30fps, 264Video input: A CSI input connector CameraVideo Outputs: mini -compatible 1.4, 1080P@30fps, DHCPAudio Output: Mini -compatiblePower Source: -USB with 5V/2AUSB 2.0 Ports: one USB 2.0 OTGButtons: Power Button, Reset ButtonLow-level peripherals: 40 Pins Header, compatible with 3uart GPIO(1x3) pin: UART, groundLED: Power led & Status ledIR: N/ASupported OS: android linxProduct size:65mm x 30mmColour:blueMaterial:PCB+MetalPackage Contents:1 x ZERO to PI3 Adapter1 x -M2 Zero development boardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
