TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
USBM2-E-SMA V2.0Supplier number:
The M.2. to USB adapter is designed to ease development and testing of systems using an M.2./NGFF module. This model is a version with aluminum enclosure which can be used in prototype or commercial installations.
Insert your USB type M.2. module such as LTE or HSPA+ to the adapter and then plug it in the USB port.
Standard SIM card push connector and external power cable for USB power adapters is provided. Mounted on PCB pad.
Note! M.2/NGFF module is not included in this article. Has to be ordered separately!
When using generic 3rd party adapters with 5G cellular data card modules, always ensure compatibility for pin-out definitions, signal voltage level, and power output capabilities for your selected cellular module, the adapter and host board prior to using the adapters. Failure to do so can result in malfunctioning systems or hardware damage to the parts.
Why should we use USB3 instead of USB2 as host system data interface if the cellular module can support both?
Cellular modules supporting higher data throughput rates like LTE Advanced, category 6 and above (300Mbps downlink and 50Mbps uplink) often support both USB3 interface as well as USB2 interface towards the host system.
It is recommended to implement and use the USB3 data interface rather than the older USB2 interface on these modules between host system and the cellular module. This because USB3 can support around 10 times higher data throughput rate compared to USB2 and avoid a possible bottleneck / limitation in the data interface between host and cellular module.
If a miniPCIe based cellular module implementing USB3 are used, please verify that conflicts don't occur towards your hosts miniPCIe socket, as the USB3 interface is not implemented by default in the miniPCIe standard and therefore signal collisions can happen between USB3 pins and PCIe data interface pins situated on same locations. Refer to the cellular module hardware guides and host system hardware guides to verify this.
The Sierra Wireless EM73, EM74 and EM75 series M.2 modules are not detected in the host system when used with the M.2 to USB adapter board? (USBM2, USB3M2)
Sierra Wireless EM73, EM74 and EM75 series M.2 modules DPR pin 25 compatibility with Bplus M.2 key B to USB adapters.
When using the Bplus USB3M2 and USBM2 adapter boards you will need to change the state of the jumper JP1 on the USB adapter board. This controls the Dynamic Power Control (DPR) pin in the M.2 socket to the cellular module.
Please remove the pin jumper piece and leave all 3 pins not connected / floating. This will allow the module to operate normally.
After changing this jumper state and powering on the module and adapter board, you should see the module appear and boot up normally in the host system device.
For further details, please relate to the Sierra Wireless related product technical specification as well as the assembly guide for the adapter boards.
