Onion company has recently returned to Crowd Supply with a open source, OpenWrt Linux driven Omega2 LTE SBC with 4G LTE and GNSS location connectivity.

“The Omega2 LTE is the latest addition to the Omega2 family of Linux IoT computers, adding built-in high-speed 4G LTE cellular data connectivity and GNSS global positioning. Smaller than a credit card, the Omega2 LTE is an all-inclusive, standalone computing device for developing cellular IoT applications. Just add LTE antennas and power.”

Since the Omega2 LTE is based on Onion’s Omega2S+, the board keeps much of the same hardware — a MediaTek MT7688 MIPS WiSoC (128Mb of DDR2/32Mb Flash), and 802.11 b/g/n/ (2.4GHz) Wi-Fi. All connectivity options, including 4G LTE and GNSS, have their own U.FL connectors, along with a Nano-SIM slot and a micro SD card slot.
