What is Special About the Librem 5 USA
Starting at the hardware level, the Librem 5 USA has Made in USA electronics, where the mainboard PCBA and type-c PCBA are manufactured at the Purism facility in the United States of America.
That means we use a secure hardware supply chain. The Librem 5 USA has three hardware kill switches that sever the power to various circuits: Cellular Modem, WiFi-Bluetooth, and Microphone-Cameras. In this state, your phone is safely cut off from any outside attackers; when the power is severed these devices do not exist.
