1 x USB 3.0 host port
1 x USB 2.0 micro OTG port
1 x Debug serial console (UART)
1 x 40 pin GPIO and 1 x 14 pin GPIO
Other features RTC backup battery connector (to keep time and date for several months without main power input)
System LED Indicators:
- Red (POWER) – Solid light when DC power is connected
- Blue (ALIVE) – Flashing like heartbeat while Kernel is running. Solid On in the u-boot stage.
Power 1 x USB Type C for Power only
DC input : 4.9V ~ 5.3V
- USB Type C 5V/3A power adapter is recommended
- IDLE : ≃ 1.1W
- CPU Stress : ≃ 3.52W (Performance governor)
- Power Off : ≃ 0W
We recommend powering the ODROID-M1S with a bundle Type C 5V/3A power adapter.

The M1S case consists of an upper case and a lower case. When both the upper and lower cases are assembled, the board inside is well secured.
However, if you remove only the upper case and connect an add-on accessory, the board will move and you will need to use two screws to secure the board to the lower case.

Flat Wafer Head Screw two M2 bolts with a length(L) of 4mm are required to secure.
It is readily available in your local bolt market of the specification.

low Flat Wafer Head Screw Bolt M2

Screw the board down on ODROID-M1S case as shown in the figure below.

Be warry of the amount of force applied while screwing down the board. The main idea is to secure the board inside the case, not overtighten them

You can install a standard 2280 size NVMe SSD.
PCIe 2.1 x 1 Lane

Expansion Connector Description

What we heard from many B2B and B2C customers is that they often didn't use the actual GPIO functionality.
Therefore, to lower production costs and product price, we decided to make GPIO header pin installation an option.
If you choose the option to install 40-pin and 14-pin GPIO headers, $3 will be added to the price. An IO-labels board for easier DIY tinkering will also be provided.
