The ODROID-N2L is the low-cost variant of our most popular and powerful ARM SBC ODROID-N2+.
This project was actually initiated at the request of several B2B customers. They were satisfied with the performance and convenience of the highly versatile N2+.
However, they wanted to embed a relatively compact, cost-effective, simple, and still high-performance SBC into their system.
Therefore, we made it!
- 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
- 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.
We 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.
Since we developed the ODROID-N2L model to be built into the device, we did not prepare a dedicated case.
We will release the files for 3D printers used for internal review and certification later.
If you need wireless connectivity, consider using a USB adapter like our WiFi Module 5BK.
We replaced the DDR4 RAM chips 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. We could find 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.
The N2L power consumption is obviously lower than ODROID-N2+ thanks to the less power demanding LPDDR4 memory and the removal of Ethernet and some other components.
We used our SmartPower3 (see https://www.hardkernel.com/shop/smartpower-iii/) to test and measure the ODROID-N2L power consumption while performing specific activities.
Average power consumption
- Ubuntu Desktop Booting : 2.429 Watt
- IDLE : 1.836 Watt
- CPU Stress (stress-ng) : 5.134 Watt
- YouTube play : 3.991 Watt
- Power Off : 0.204 Watt
The stock cooling fan must always rotate to avoid thermal throttling when running a very heavy computing load with an overclocked 2.4Ghz CPU clock frequency.
If your system design doesn’t allow moving parts such as a cooling fan, you will need to replace it with a passive heatsink. In this scenario, you may need to limit the maximum CPU frequency to lower than 2Ghz if the working ambient temperature is high and computing load is very heavy.
Since the heat dissipation characteristics are somewhat diminished, the maximum clock frequency of the CPU may be slightly lowered and will need to be taken into consideration according to the purpose.
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)
As we plan to distribute development samples to forum community developers from next week, we expect that many 3rd party OS images will appear within a few months.
- S922X Hexa-core CPU
- 2GB or 4GB LPDDR4x RAM
- DC Power Jack (7.5V ~ 16.5V wide input range)
- HDMI 2.0
- 1 x USB 3.0, 1 x USB 2.0
- MIPI-DSI (Not supported yet)
- Micro SD slot
- UART for System console
- Cooling Fan connector
- 40 pin GPIO header
- eMMC Module socket
Note that the MIPI-DSI port is not enabled at this moment and may take several months to develop and distribute a device driver. If your major application needs a MIPI display device, please wait to purchase the N2L until after a working driver is available.
