Challenger+ RP2350 NB-IoT board targets off-grid IoT builds with 4G LTE, GNSS and battery support
A compact new developer board built around Raspberry Pi’s RP2350 microcontroller is aiming at connected sensor projects that need to run beyond Wi‑Fi range.
The Challenger+ RP2350 NB‑IoT combines cellular options, satellite positioning and battery power in a small, maker-friendly design.
The board is positioned for low-power IoT deployments rather than desktop-class computing, using the RP2350 as its core controller. Like other RP-series microcontroller boards, it focuses on interfacing with sensors and actuators through standard pin headers for data collection and control tasks.
Cellular and GNSS in one board
To support field deployments, the Challenger+ includes cellular connectivity alongside Wi‑Fi, enabling telemetry even where local networks are unavailable. It also integrates a GNSS module with support for GPS and Galileo, making it suitable for tracking and location-stamped measurements.
Power can be supplied over USB‑C for development, but the design also supports battery operation for off-grid use. That combination is intended to simplify builds such as remote environmental monitors, asset trackers or mobile data loggers.
Developer tools and onboard storage
The board includes 8 MB of flash storage and supports popular embedded workflows, including Arduino IDE, MicroPython and CircuitPython. For connectivity, cellular use typically requires a compatible plan, and the vendor also markets a SIM option intended to work across multiple countries.
Pricing is listed at about $60, placing it above basic RP2350 boards but closer to devices that bundle modem and GNSS hardware. For developers who would otherwise add those modules separately, the integrated approach could reduce assembly complexity and improve portability.
