RF StateSide, LLC is an RF and embedded engineering lab and consulting brand operated by Ray Faucher (KB1SO), based in New Hampshire, USA. It is not a general-purpose SaaS developer tool; instead, it offers a combination of hardware, firmware, and desktop software for RF power amplifiers, power-supply control, station automation, and marine electronics, along with an online store and engineering consulting services.
Its projects cover a fairly complete engineering workflow. RaySspaController is based on Teensy 4.x and is designed for solid-state amplifier control across 1β4 LDMOS modules, including bias, temperature, SWR, overdrive, overcurrent protection, and a Nextion touchscreen interface. RayEltekController is based on ESP32-S3 and targets Eltek power systems, supporting Ethernet/WiβFi, IΒ²C, CAN, REST, WebSocket, optional MQTT, and a Qt desktop client. RayPowerMeter, RayCoupler, RayRigAntSw, and related projects fill out RF measurement and station-switching use cases. On the marine side, RayVessel and RayNmeaSimulator support NMEA2000/NMEA0183, vessel dashboards, and testing for chartplotters/autopilots.
The website states that hardware, software, firmware, and digital downloads are sold through its store, with payments processed by Stripe and shipping handled via Shippo, but it does not disclose specific pricing. Eligible physical goods can be returned within 14 days after delivery, while digital products are generally non-refundable once downloaded or licensed. In terms of documentation, the site provides overviews, specifications, and interface descriptions, and mentions firmware, schematics, configuration guides, and JSON API references. However, some wiring guides, pinouts, and OTA guides are still marked as Coming soon, indicating that the documentation is still being completed.
Its strengths are a clearly defined vertical focus and coordinated design across hardware, firmware, desktop applications, and remote protocols, making it suitable for professional RF/embedded integration. It also spans multiple technology stacks, including Qt/C++, .NET Blazor, ESP32, Teensy, and Raspberry Pi. The drawbacks are that several projects are still under development, open-source licensing, pricing, and commercial support SLAs are not clearly specified, and it is difficult for general software developers to reuse directly.
RF StateSide is better suited to advanced amateur radio operators, RF engineers, power amplifier/power-system developers, marine electronics testers, and teams that need DAS/RF architecture reviews. The scraped text does not provide information on accessibility from China, so the status is unknown. Since payments use Stripe, users in mainland China may need to consider international card availability, logistics, and after-sales communication. If you only need general embedded development, ecosystems such as ESP-IDF, Arduino/Teensy, Qt, OpenPlotter, or Signal K may be more appropriate.
