ODROID-N2L is a variant SBC in small form factor and some peripherals
are removed from ODROID-N2PLUS based on S922X SoC.
- On-board ethernet is removed
- On-board RTC is removed
- USB 3.0 hub is removed, so one USB 2.0 and one USB 3.0 host ports
are available
- Huge heatsink is replaced with 40x40mm heatsink, 5V active heatsink
is recommended or a tall passive sink is optional
- 3.5mm earjack is removed
- IR remote receiver is removed
- MIPI DSI port is added
It doesn't use the odroid-n2 board support since ADC revision
collides with Odroid-N2+ and since it doesn't have on-board ethernet
no need to load the MAC address from eFuses.
