The Libre Computer Board ALL-H3-CC from Libre Technology is a Raspberry Pi B+ form factor single board computer based on the Allwinner H3 SoC. The board has 1GB DDR3 SDRAM, provided by 4 2Gb chips. The mounting holes and connectors are in the exact same position as on the Raspberry Pi B+. Raspberry Pi B+ like peripherals supported on this board include: - Power input through micro-USB connector (without USB OTG) - Native 100 Mbps ethernet using the internal PHY, as opposed to USB-based on the RPi - 4x USB 2.0 host ports, directly connected to the SoC, as opposed to being connected through a USB 2.0 hub on the RPi - TV and audio output on a 3.5mm TRRS jack - HDMI output - Micro-SD card slot - Standard RPi B+ GPIO header, with the standard peripherals routed to the same pins. * 5V, 3.3V power, and ground * I2C0 on the H3 is routed to I2C1 pins on the RPi header * I2C1 on the H3 is routed to I2C0 pins on the RPi header * UART1 on the H3 is routed to UART0 pins on the RPi header * SPI0 on the H3 is routed to SPI0 pins on the RPi header, with GPIO pin PA17 replacing the missing Chip Select 1 * I2S1 on the H3 is routed to PCM pins on the RPi header - Additional peripherals from the H3 are available on different pins. These include I2S0, JTAG, PWM1, SPDIF, SPI1, and UART3 In addition, there are a number of new features: - Console UART header - Consumer IR receiver - Camera interface (not compatible with RPi) - Onboard microphone - eMMC expansion module port - Heatsink mounting holes - Power button The power button requires corresponding software for the embedded coprocessor to properly function. This patch adds a dts file for this board that enables all "onboard" peripherals currently supported. This means no display or camera support.
