Raspberry Pi HAT does 3G/HSPA, and GNSS too
Linkwave’s “Pilot” is a Raspberry Pi HAT add-on with a Sierra Wireless HL 3G/HSPA radio, a SIM slot, as well as a GNNS location chip.
Sierra Wireless announced that Linkwave Technologies has released a $101 3G/HSPA wireless add-on for the Raspberry Pi. The Pilot board incorporates a Sierra Wireless HL module for 3G/HSPA cellular data service, plus a 3V micro-SIM lets you load a 3G card of your choice. The board complies with the Raspberry Pi HAT add-on spec, and can be powered separately or directly from the Raspberry Pi 2, 3, or Zero.
