1.
There are two configurations of i.MX8 Processor, hence in this document i.MX8 is used to represent either i.MX8QM
or i.MX8QP based on SOM Part Number.
2.
The i.MX8 can support up to 16GB RAM but considering the available LPDDR4 configuration, it can support 8GB
RAM by using two 4GB LPDDR4 chips. If 8GB (64Gb) LPDDR4 chips are available then 16GB RAM can be supported
on Board.
3.
Memory Size will differ based on iWave’s SOM
Product Part Number.
4.
16GB and 32GB eMMC are already validated on i.MX8 QM platform.
5.
JODY-W2 Wi-Fi is supported by using SDIO interface, hence On SOM microSD will be an optional feature.
6.
802.11ax (Wi-Fi 6) can be supported by changing from JODY-W2 to JODY-W3
7.
The i.MX8 support HDMI or Display Port through same pins, hence any one can be supported at a time based on
SOM part Number.
8.
The i.MX8 support MIPI_DSI and LVDS interface, but in SMARC Specification LVDS and MIPI_DSI interface pins are
multiplexed hence any one can be supported at a time based on SOM part Number.
9.
UART1 interface of i.MX8 is connected to on SOM Bluetooth module in the default configuration. One more UART
can be supported with CTS and RTS if Bluetooth is not supported
10.
In default configuration 12 GPIOs are supported, SMARC GPIO_12 and SMARC GPIO_13 are Optionally supported.
