Expansion card features:1. Using a unique adapter design, direct insertion, a strong sense of unity.2. At the time, the - port is converted into a 3B universal female port, which is convenient to .3. At the time, the GPIO height position perfectly inherits the GPIO height of 3B and , so customers who need to insert various GPIO expansion boards can insert perfectly without changing the height.Interface Introduction: 1. Onboard 4-way USB expansion port, 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 / W/ WH and Banana Pi M2 , 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 BPI-M2 CPU: H3+ Quad-core Cortex-A7 H265/HEVC 1080PGPU: Mali400MP2 GPU @600MHz, Supports OpenGL ES 2.0Memory (SDRAM): 512M DDR3 (shared with GPU)Onboard : TF card (Max. 64GB)Onboard Network: (but can extension with PIN define)PoE : 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 - 1.4, 1080P@30fps, DHCPAudio Output: Mini - Source: -USB with 5V/2AUSB 2.0 Ports: one USB 2.0 OTGButtons: Button, Reset ButtonLow-level peripherals: 40 Pins Header, with 3uart GPIO(1x3) pin: UART, groundLED: led & Status ledIR: N/ASupported OS: android linxProduct size:65mm x 30mmColour:blueMaterial:PCB+MetalPackage Contents:1 x to PI3 Adapter1 x BPI-M2 development boardOnly the above package content, other products are not included.Note: Light reflection and different displays may the color of the item in the a little different from the real thing.
