M.2 Connectors

UDOO BOLT GEAR features two M.2 connectors on the bottom of the board.

M.2 SATA/PCI-e Slot: Socket 2 Key B type 2242/3042/2260

The mass storage capabilities of the UDOO BOLT GEAR are completed by an M.2 SSD Slot, which allows plugging M.2 Socket 2 Key B Solid State Drives with SATA interface or PCI-e x2 interface (PCI-e x1 is also supported). The connector used for the M.2 SATA/PCI-e slot is CN20, which is a standard 75 pin M.2 Key B connector.

On the UDOO BOLT GEAR board there is also a Threaded Spacer which allows the placement of M.2 Socket 2 Key B SATA/PCI-e modules in 2260 size.

In the Official Accessories section you can find a M.2 SSD Transcend MTS600 2260 drive compatible with this connector, available in the UDOO shop.

It is possible to also place modules in 2242 or 3042 size, by using a M/F Spacer, which allows fixing the M.2 module on the spacer already available on the PCB, deemed for the fixing of the M.2 Key E.

The PCI-e x2 interface can also be used for different purposes other than SSD modules, but it is important that the CONFIG_1 signal is driven properly (it can be left unconnected on PCI-e based modules, due to the presence of the pull-up resistor on the platform).

For example you can connect other accessories as the official M.2 dual Ethernet Module Kit or an adapter from M.2 to PCI-e 2x as used in this project to connect an external GPU.

M.2 NVMe Slot: Socket 3 Key M Type 2280

Another possibility to connect mass storage devices is given by the M.2 Key M Slot, which allows the plugging of M.2 High Capacity SSD NVMe drives with PCI-e x4 interface.

The connector used for the M.2 SSD slot is CN17, which is a standard 75 pin M.2 Key M connector, located at the bottom of the board.

On the UDOO BOLT GEAR board there is also a Threaded Spacer which allows the placement of M.2 Socket 3 Key M PCI-e SSD modules in 2280 size.

Searching in the web, you can also find M.2 Key M to PCI-e 4x to connect an external GPU.
For example, we used this one or this other and they work good and can be used also with the board inside the official UDOO BOLT GEAR metal case. These accessories are not supported by UDOO.

M.2 Connectivity Slot: Socket 1 Key E Type 2230

It is possible to increase the connectivity of the UDOO BOLT GEAR board by using M.2 Socket 1 Key E connectivity modules (i.e. modules with functionalities like WiFi + Bluetooth).

The connector used for the M.2 Connectivity slot is CN19, which is a standard 75 pin M.2 Key E connector.

On the UDOO BOLT GEAR board there is also a Threaded Spacer which allows the placement of M.2 Socket 1 Key E connectivity modules in 2230 size.

The UDOO BOLT GEAR comes with a M.2 Wi-Fi Intel dual band ac Wi-Fi + BT 4.2 5ghz + adhesive antenna module compatible with this connector, you can find more info in the Official Accessories section.
