Green rectangular circuit board with two M.2 slots, a nano-SIM slot and a 10-pin GPIO header

Khadas

Khadas M2X Extension development board 94.0 x 56.0 x 5.5 mm

SKU CH-DAYC-MVAZA

Adds NVMe storage and 4G LTE with a nano-SIM slot to compatible Khadas boards

  • Add fast NVMe storage with M-key M.2 slot for 2280 SSDs
  • Enable 4G LTE connectivity via B-key M.2 slot and nano-SIM
  • Expand I/O options using 10-pin GPIO header for custom projects
  • Monitor cellular status instantly through 4G Active LED indicator
  • Ultra-thin 5.5 mm profile fits compact VIM3, VIM3L or Edge-V builds

Ultra-thin extension board

The Khadas M2X Extension board adds M.2 expansion to VIM3, VIM3L and Edge-V single-board computers. It measures 94.0 x 56.0 x 5.5 mm and fits directly onto the host board. Developers and makers use it to attach fast storage or cellular connectivity to their edge-computing projects.

M.2 slots and GPIO access

One M-key slot accepts a 2280 NVMe SSD while a B-key slot supports a 4G LTE module with a built-in nano-SIM holder. A 10-pin GPIO header remains exposed for additional peripherals. The board connects through a single PCIe lane on VIM3 and VIM3L, and uses four lanes for SSD-only operation on Edge-V.

Storage and cellular headroom

The M-key slot provides headroom for high-capacity NVMe drives, removing the storage bottleneck of onboard eMMC. The B-key slot enables mobile broadband when a compatible module and SIM are installed. Edge-V users gain SSD support but cannot use the LTE function. Builders needing more than one NVMe drive or a second cellular modem must look elsewhere.

Întrebări despre acest articol

Does the 10-pin GPIO header carry the PCIe x1 lane that the VIM3 needs?

The board routes a PCIe x1 lane to the M-Key slot for VIM3 and VIM3L, while the 10-pin header provides general GPIO access.

How much heat does the M.2 NVMe SSD generate when the board runs continuously?

The extension board itself is passive; SSD temperature depends on the drive you install and the airflow in your enclosure.

Which single-board computer must I already own to use the M-Key NVMe slot?

Compatible hosts are the VIM3, VIM3L or Edge-V; the Edge-V only supports the SSD function.
