Tue Jan 16 02:51:57 PST 2024
From: Frieder Schrempf <frieder.schrempf at kontron.de>
The Sielaff i.MX6 Solo board is used as controller and user interface
in vending machines. It is based on the i.MX6 Solo SoC and features
the following peripherals and interfaces:
* 512 MB DDR3 RAM
* 512 MB NAND Flash
* 1 MB NOR Flash
* SD card
* Debug LED
* Debug UART
* Key Inputs
* RTC
* RS232
* 100 MBit Ethernet
* USB Hub
* USB OTG
* HDMI
* 7" LVDS IPS panel
* PWM Backlight
* Optional Extension Board with USB Ethernet NIC
