Banana Pi P2 Zero is H2+-based board by Sinovoip internally similar to Banana Pi M2 Zero. It features: - Allwinner H2+, Quad-core Cortex-A7 - 512MB DDR3 SDRAM - 8G eMMC flash - MicroSD card slot - 100M LAN - WiFi (AP6212) & Bluetooth onboard (SDIO + UART) - Micro USB OTG port - Micro USB connector (power only) - Mini HDMI - 40 PIN GPIO includes UART, SPI, I2C, IO etc. - GPIO-connected key and LED - CSI connector - IEEE 802.3af PoE standard PoE module support (optional) This adds support for v1.1 revision. There was also v1.0 available which has different SDcard CD polarity and Ethernet port LEDs disconnected in layout.
