From: Alex Gonzalez
Date: Tue Sep 04 2018 - 11:28:51 EST

The ConnectCore 6UL Single Board Computer (SBC) Pro contains the
ConnectCore 6UL System-On-Module.

Its hardware specifications are:

* 256MB DDR3 memory
* On module 256MB NAND flash
* Dual 10/100 Ethernet
* USB Host and USB OTG
* Parallel RGB display header
* LVDS display header
* CSI camera
* GPIO header
* I2C, SPI, CAN headers
* PCIe mini card and micro SIM slot
* MicroSD external storage
* On board 4GB eMMC flash
* Audio headphone, line in/out, microphone lines
