ODROID-N2+ with 4GByte RAM (G200702239825) Hardkernel N2plus

ODROID-N2+ is a revision from ODROID-N2.

  • – Maximum CPU clock of Quad-core Cortex-A73 is increased to 2.4Ghz from 1.8Ghz.
  • – Maximum CPU clock of Dual-core Cortex-A53 is increased to 2.0Ghz from 1.9Ghz.
  • – On-board RTC backup battery holder is mounted on the board.

The main CPU is based on big.Little architecture which integrates a quad-core ARM Cortex-A73 CPU cluster and a dual core Cortex-A53 cluster with a new generation Mali-G52 GPU.
Thanks to the modern 12nm silicon technology, the A73 cores run at 2.2Ghz without thermal throttling using the stock metal-housing heatsink allowing a robust and quiet computer.
The CPU multi-core performance is around 20% faster and the GPU is 10% faster than the N1. The N2+’s DDR4 RAM is running at 1320Mhz with 1.2volt low power consumption.
The large metal housing heatsink is designed to optimize the CPU and RAM heat dissipation and minimize throttling. The CPU is placed on the bottom side of the PCB to establish great thermal characteristics.

More information is on our WiKi.

Optional Active Cooler


Heatsink size comparison : The system height decreased from 34mm to 29mm approximately thanks to the slimmer heatsink.

GPIO (40Pin header)

The N2 GPIO interface is similar to C2 and fully supports a 3.3Volt interface while N1 could only support 2.8Volt IO. This is beneficial for using various peripherals without complicated level shifters.
Another big improvement is a faster SPI bus interface. Its maximum frequency is over 150Mhz, and we will try to implement a DMA driven SPI driver for faster LCD display.

Power consumption
Idle state: 1.6~1.8 Watt
Heavy load state: 5.9~6.2 Watt (stress-ng –cpu 6 –cpu-method matrixprod)
No cables are attached except DC power input and USB-UART debug console cable.


Software support

Ubuntu 20.04 LTS images are available with Kernel version 4.9.230 LTS as of today. This LTS kernel version will be officially supported until Jan, 2023.
The Mali G52 GPU Linux driver works only on the framebuffer and Wayland. We tested the latest PPSSPP emulation and it can handle x3 scaling on a 4K display nicely with well implemented VSYNC.
The fb-dev Mali driver supports OpenGL-ES 1.1, 2.0, 3.0 and 3.1 as well as OpenCL-1.2 and 2.0 at this moment. Note that you have to use the Minimal Ubuntu OS image to utilize the GPU acceleration instead of the Ubuntu Mate image.

There is a Linux Wayland driver too. Ubuntu 20.04 Gnome desktop works with fully accelerated hardware GPU on a modern Kernel 5.7.
This trial upstream OS image is available on the forum.

Android 9 Pie is ready, and you can access a source code BSP and pre-built image together. Note that GUI layer(SurfaceFlinger) resolution is limited at 2K while the video layer is true 4K.
The Android platform is based on a full 64bit system software with a Vulkan capable GPU driver.
