What is it?

Blueberry PI

I have designed this SBC, because the sheer power of this SoC, at very low power consumption, combined with its display capabilities, it offers options that makers have never seen before.

The Blueberry PI features:

• Ethernet Jack
• 1 USB Host Port / 1 mini USB port
• MIPI CSI interface, pin compatible with the Raspberry Pi camera (no support in the linux kernel yet)
• pinheader for an OV2640 and an OV7670 parallel camera
• Wifi and Bluetooth (RTL8723BS)
• parallel RGB interface, compatible with 40pin parallel RGB displays
• Audio jack (3,5mm)
• onboard microphone
• five buttons for play, pause, next, previous and reset
• a 26pin Raspberry PI compatible header
• footprint for SPI Flash
• SD card slot

The Blueberry PI can boot from an SD card or SPI Flash. The Blueberry PI comes fully assembled, except for the SPI Flash and the NS2009 touch IC. You will have to get them on your own.

Processor Specs:

• ARM Cortex-A7 @ 1.2GHz
• 64 Megabyte of RAM @ 320 MHz

SD / MMC Interface

• up to three SD / MMC controllers
• 1 / 4-bit SD, SDIO, MMC mode

PWM

• up to two PWM channels

• up to 24 MHz output frequency

Video output

• Support RGB Interface with DE/SYNC mode, up to 1024x768 @ 60fps

Camera

• Still capture resolution up to 5M with parallel interface

• Video capture resolution up to 1080p @ 30fps with parallel interface

Audio codec

• two audio DAC channels

• one differential microphone input

• one stereo headphone output

• one low-noise analog microphone bias output

USB

• One USB 2.0 OTG controller with integrated PHY

• Support High-speed, Full-speed and Low-speed in host-mode

Ethernet

• Integrated an internal 10/100M PHY

• support full-duplex and half-duplex operation

UART

• up to three UART controllers

SPI

• Full-duplex synchronous serial interface

• Master / slave configurable

• Mode 0-3 are supported

I²C

• up to two I²C controller

• support Standard and Fast mode

Softwaresupport (Linux Kernel)

The support of mainline U-boot and mainline Linux kernel is in good progress. You find all the details at the Linux mainlining effort at sunxi.

The mainline linux kernel (4.19) has support for:

• basic SOC features
• Ethernet
• USB
• parallel CSI
• RGB and TCON
• UART
• I²C
• SPI
• SDIO
• Audio
• LRADC0
• RTC
• Watchdog

Whats not implemented:

• CPU frequency scaling
• MIPI CSI
• Video Engine (encoding / decoding video)
