Description
ODROID-N2L
Compact, cost-effective, simple, and still high-performance SBC.
- Smaller and neater form factor: 69 x 56mm
- Small size allows for mounting inside a variety of small devices
- Suitable for various standalone embedded system which don’t require Ethernet connectivity
- Suitable for building robots, drones, arcade consoles, human-machine-interface devices, and many other applications
- Faster and lower power consumption LPDDR4 RAM
- Lightweight
- Low cost
While the letter ‘L’ does not refer to any specific word, it has various meanings such as Little, Leaf, Lynx, Lovely, Lumen, LPDDR and Light. The N2L has removed some features which were available on the N2+ to reduce the material cost and to minimize the PCB form factor. Ethernet, RTC, SPI-Flash, OTG port, Analog audio output, IR receiver, three USB 3.0 ports and the large heatsink frame were removed.
DDR4 RAM chips were replaced with a single LPDDR4 chip to minimize the PCB form factor and reduce power consumption. As a bonus, around 20% higher DRAM interface clock frequency is an obvious and important improvement. It was found that 10% to 20% of increased system performance compared to the original N2+ in various benchmark test results.
The GPU benchmark glmark2-es2 also showed about 10% of increased performance which is very similar to the improvement of the memory bandwidth (MBW) test.
OS images and CAUTION
Because the DRAM chip was changed from DDR4 to LPDDR4, the existing OS image for N2/N2+ will NOT boot on N2L.
It is necessary to modify the boot loader files at a minimum.
Currently, the following OS images for N2L have been prepared.
- Android 9.0 64bit and 32bit images
- Ubuntu 22.04 Mate / Minimal with Kernel 4.9
- Ubuntu 22.04 Desktop with Kernel 5.15 and upstream
- EmuELEC (TBD)
