RAKwireless WisBlock Mini Base Board RAK19003
The RAK19003 WisBlock Mini Base Board is a compact 30x35mm platform for rapid IoT prototyping, designed to host the WisBlock Core MCU and two expansion modules via a 24-pin WisConnector. It offers flexible power from USB, LiPo, or solar and provides I2C, UART, GPIO, and analog interfaces for sensor integration and low-power applications.
Features
- Compact 30 x 35mm footprint for space-constrained IoT deployments and portable designs.
- Triple power supply options: 5V USB, 3.7V LiPo battery, and 5V solar panel inputs for field flexibility.
- Plug’n’Play modularity with a 24-pin WisConnector for easy integration of WisBlock Core MCU and sensor modules.
- Low-power optimized design with controlled power rails to connected modules for extended battery life.
- Comprehensive debug interface via USB Type-C port and accessible I2C, UART, GPIO, and analog input solder pads.

The RAK19003 WisBlock Mini Base Board is an industrial-grade foundation for building compact, modular IoT nodes. Its core function is to mechanically and electrically interface a WisBlock Core MCU (like the RAK4631) with up to two additional WisBlock I/O or sensor modules, enabling rapid system assembly without complex wiring. The board’s power management system intelligently handles multiple input sources, prioritizing and switching between USB, battery, and solar to maintain continuous operation in remote deployments.
Engineered for low-power applications, the base board provides controlled power domains to its connected modules, allowing the main MCU to put peripherals into deep sleep. The exposed solder contacts for I2C, UART, GPIO, and analog signals offer direct access for custom circuitry or debugging. With a USB Type-C debug port, user-definable LEDs, and a reset button, it delivers a complete development environment for prototyping LoRaWAN, BLE, or other wireless sensor networks before scaling to production.
