Wed Apr 8 21:54:45 CEST 2015
The GW551x is a small form factor board based on the IMX6 SoC that includes:
* up to 512MB DDR3 memory
* up to 2GB NAND flash
* 1x miniPCIe socket (with USB)
* HDMI out (micro-HDMI)
* HDMI in (micro-HDMI)
* TTL level I/O (supported by GW16111 breakout board):
* I2C
* 2x UART
* CAN
* 2x DIO (GPIO/PWM)
* USB OTG
