2.4 USB Interface
M280 and M280V module are compliant with USB2.0 in all three modes (Low speed, Full speed, and high speed).
When two devices are connected via a USB interface, one of the devices must act as a host, and the other device
must act as a peripheral. The host is responsible for initiating and controlling traffic on the bus. For example, the
USB specification requires PCs to act as hosts, and other devices such as M280 to act as devices.

2.5 USIM Interface
The universal subscriber identification module (USIM) is a smart card for UMTS/GSM cellular applications. The
USIM provides the required subscription information to allow the mobile equipment to attach to a GSM or UMTS
network. The USIM also provides the subscriber's verification procedures as well as authentication methods for
network authentication during the network registration procedures. Upon power-up or after a soft-reset, the clock and
data lines to the USIM will be active through the initialization process. Table 2-4 shows the SIM card pin definition.
It’s recommended to implement hardware USIM detection mechanism or complete avoiding USIM hot-plug through
mechanical design. The reference design for hardware USIM detection is provided in the “Application Note for
BandLuxe Module USIM Detection Recommendation”.
