Embedded {hardware} specialist SudoMaker has launched a “next-gen” debug instrument for these working with LoRa radio networks, the LoShark — and regardless of trying like a easy USB dongle it runs mainline Linux straight by itself system-on-module.
“The LoShark is a USB key-sized system, designed with a eager concentrate on providing sturdy LoRa connectivity and debugging capabilities,” the corporate explains of its newest launch. “It is engineered to function each independently and together with a PC, opening up a flexible vary of use-cases. Designed with a USB key type issue, LoShark may be simply plugged right into a PC or function independently when related to a USB energy financial institution.”

At its easiest, the LoShark can act as a USB radio for LoRa networks — but it surely’s really a completely self-contained single-board pc (SBC) constructed round SudoMaker’s X1501 Pico system-on-module. Meaning an Ingenic X1501 MIPS32r2 processor core working at 1GHz, 8MB of LPDDR RAM, and the power besides mainline Linux straight on-device. It is this which supplies the gadget the power to work as a stand-alone system, related to nothing however energy and an appropriate antenna.
“The LoShark’s main power is its capability to execute JavaScript (ES2015) by means of our runtime, Resonance,” SudoMaker claims. “This characteristic permits customers to program particular duties, serving as a strong instrument for LoRa debugging, similar to capturing packets and sending LoRa messages both manually or programmatically, at minimal delay.”
As a Linux system, although, the JavaScript help is elective: the corporate guarantees that the LoShark may run bare-bones Linux functions, written in any language that may output a MIPS32 executable. Packages may be saved within the alternative of 256MB or 4GB of storage — related over an eight-pin Safe Digital interface.

The board design additionally contains a HJSIP HJ-68LR LoRa module, primarily based on the Semtech SX1262 transceiver, for LoRa connectivity, and the choice to have 8MB of further pseudo-static RAM (PSRAM) and a real-time clock with supercapacitor backup fitted.
Extra info on the challenge is out there on SudoMaker’s Hackster.io web page, whereas {hardware} is out there to order on the SudoMaker web site beginning at $49.99 for the 256MB variant with out PSRAM and RTC. Schematics and software program are additionally out there on the corporate’s GitHub repository,
