Which seems to be an iteration of the Precursor (Mobile, Open Hardware, RISC-V System-on-Chip (SoC) Development Kit) by Bunnie Huang and Sean Cobs
> Part of the purpose of Precursor is to validate the system-on-chip (SoC) design we hope eventually to produce as a custom ASIC for use in future such products. This SoC, which we call "Betrusted-SoC," is meant to be the central pillar of security for devices like Precursor. The version of Betrusted-SoC used in Precursor is based on a Xilinx FPGA and has the following features [...] [1]
As for the person who replied to you requesting LTE: won't happen, there's no completely FOSS stack for LTE. Always there is closed source firmware due to regulations. Oh, that wonderful world of transceivers. If you want FOSS, go wired. Tho it seems Precursor found a way to utilize Wi-Fi with a FOSS stack?
