to use with spi-nand flash build & flash this Linux tree:

OpenWRT: https://github.com/bhgv/openwrt

main build board now is Blueberry Pi 7.1.2.esp32.no-lan.gsm-a9g. because a9g gsm module is much better then sim800c. because of open source SDK and support of GPS.

but still work-in-progress. not finished.

sources of Linux kernel (4.10.15) for this board(s). preconfigured: https://github.com/bhgv/linux

precompiled Linux-4.10.15 SD-image with support of fb-graphics an resistive touch: https://github.com/bhgv/linux/releases/tag/1.0a

exp2_Blueberry Pi 7.1.2.licheepi-zero.esp32.no-lan.gsm-a9g.no-50p

most simplest to assembly choise

cheap Lichee Pi zero module as CPU and CPU-power module. also used its TFT connector
ESP32-WROOM as wifi/bluetooth module
A9/A9G as GSM/GPS module
connector for cheap popular gt911 capacitive touchscreens (workable driver for gt911 is included to this Linux)
includes Li-Ion/polimer battery charging/powering circuits

Blueberry Pi 7.1.2.esp32.no-lan

(not finished yet)

removed lan port,
added 50pins fpc RGB connector for popular 7" tfts (AT070TN[90, 91, 92, 93, 94]) in parallel to 40pins one,
connector for capacitive touchscreens (i2c1),
power converters for 50pins socket,
25% smaller board.
esp32 now wired as wifi/bluetooth and as io expander-coprocessor.

Blueberry Pi 7.1.1+ESP32-S

(not finised yet)

other power controller(s). 3 cheap and easy to solder chips in sot23-6,
a try to use ESP32-S module as a WiFi/Bluetooth co-processor.

Blueberry Pi 7.1+axp203

is the Blueberry Pi 7.1 board but with AXP203 power controller, not EA3036. and has DC-DC step down (5-12v) on power input.

Blueberry PI 7.1

Added:

LVDS interface with cheap SN65LVDS84 serialiser,
resistive touchscreen controller TSC2003 + pinheader for resistive touch,
flash w25q128,
more popular MicroSD card slot,
datasheets for them

Removed:

pinheader for OV7670

Blueberry PI

Another fruit single board computer (SBC), based on the Allwinner V3s system on a chip (SOC). The Allwinner V3s comes in an easy to solder 128pin TQFP package.

The Blueberry PI features:

100 mbps Ethernet
1 USB Host Port / 1 mini USB port
MIPI CSI interface (unfortunately no support in the linux kernel yet)
Pinheader for an OV2640 and an OV7670
Wifi and bluetooth
RGB interface for connecting displays
Audio jack
an onboard microphone
four buttons for play, pause, next and previous
a Raspberry PI compatible header
SPI Flash
SD card slot

The Blueberry PI can boot from an SD card or SPI Flash. Since the V3s doesn't have a standard video output, I'm planning on creating a video addon board which provides VGA or HDMI. In combination with the ADV7611 it is possible to capture HDMI.
