# ODROID boards for IoT: M1S (low power, eMMC + NVMe), N2L (no Ethernet) and H4 (x86)

> Hardkernel's ODROID-M1S (RK3566) has soldered 64 GB eMMC, an NVMe slot and about 1 W headless idle power; the N2L (Amlogic S922X) drops Ethernet for size and power; the H4 is an x86 board with the Intel Processor N97, SATA and 2.5GbE.

Hardkernel's ODROID line covers low-power Arm boards and x86 boards. Three representative models, per Hardkernel's product pages:

## ODROID-M1S: low-power gateway with real storage

| | ODROID-M1S |
|---|---|
| SoC | Rockchip RK3566 |
| RAM | LPDDR4; sold in 4 GB and 8 GB versions (plus a 2 GB "Lite" version) |
| Storage | **64 GB eMMC soldered on board**, M.2 M-key slot, **PCIe only (NVMe)**: M.2 SATA does not work; PCIe 2.1 x1, slower than the original M1 |
| Network | gigabit Ethernet |
| GPIO | 40-pin header plus a 14-pin header |
| Power (Hardkernel's measurements) | about 1.0 W idle headless, about 0.7 W with Ethernet unplugged, about 3.2 W CPU stress test |

A strong fit for always-on IoT gateways: no SD card to wear out, low idle power, NVMe for databases or recordings.

## ODROID-N2L: compact and no Ethernet

| | ODROID-N2L |
|---|---|
| SoC | Amlogic S922X, 12 nm: 4x Cortex-A73 @ 2.2 GHz + 2x Cortex-A53 @ 2 GHz |
| RAM | 2 or 4 GB LPDDR4 |
| Storage | eMMC module connector (8–128 GB modules) |
| Network | **none onboard**. Hardkernel removed Ethernet (and more) versus the N2+, and notes that USB 3.0-to-Ethernet adapters cannot be used reliably |
| GPIO | 40-pin header, including 2 ADC inputs (10-bit, 1.8 V max) |

Good for standalone embedded systems (kiosks, displays, local control) that don't need wired networking.

## ODROID-H4: x86 in SBC size

| | ODROID-H4 series |
|---|---|
| CPU | Intel Processor N97 (x86-64) |
| RAM | DDR5 SO-DIMM (single channel, a limitation of the Alder Lake-N platform) |
| Storage | SATA ports (2–4 depending on variant) and NVMe |
| Network | 2.5GbE (up to four ports on some variants) |

Choose x86 when you need software only built for amd64, a standard PC boot flow, or SATA disks for a NAS. Note: at the time this was written, Hardkernel's product page said H4 production and sales were **suspended** because of Intel CPU supply issues. Check availability before designing around it.

## Claims

- Hardkernel reports that a headless ODROID-M1S idles at close to 1.0 W, and about 0.7 W with the Ethernet cable unplugged. (unverified)
- The ODROID-H4 series uses the Intel Processor N97 and supports DDR5 memory. (unverified)
- The ODROID-N2L uses the Amlogic S922X (quad-core Cortex-A73 at 2.2 GHz plus dual-core Cortex-A53 at 2 GHz) and has no onboard Ethernet. (unverified)
- The ODROID-M1S uses the Rockchip RK3566, has 64 GB of eMMC soldered to the board and an M.2 slot that supports only PCIe (NVMe), not M.2 SATA. (unverified)
