I'm looking for an IoT device which has Bluetooth, GPS, a USB port and which can support a module for an alarm. The end product is a wearable device therefore the device should be small.

It should be something like an Arduino or a Raspberry Pi. The size should be as small as possible but it should be compatible with all the above mentioned features.

    What sort of device are you specifically looking for? To be able to answer this, you should really specify exactly what type of device you want (do you want a board that you can program and put into a case?). Do you also know more exact dimensions that you need to help narrow down the search?

    Side note: special attention should payed when buying this module, because some of them has only GSM/GPRS support by default and firmware upgrade is needed to enable Bluetooth or/and GPS functionalities.

Shameless plug In about a years time you can get an nRF91 + nRF52840 combo. LTE(CATM1 and NbIoT), GPS, BLE, USB, 802.15.4, etc, that uses a fraction of the power of current devices, and got plenty of µC-resources to spare.
