WisBlock Base RAK19001 – Modular IoT Base Board

The WisBlock Base RAK19001 is a core foundation for building modular IoT systems. It connects the WisBlock Core with various WisBlock IO and sensor modules through a highly expandable board layout. It includes one slot for the Core, two IO slots, and six sensor slots (A to F)—supporting advanced use cases with multiple interconnected modules.

All critical I/O pins—including UART, I2C, SPI, and USB—are exposed via two 2.54 mm pitch headers, allowing integration of third-party or custom modules. The USB Type-C port connects directly to the WisBlock Core’s USB interface (if supported) or through a USB-UART converter and can be used for firmware upload, serial communication, or charging a battery.

RAK19001 supports multiple power input options, including 5V USB, 3.7V rechargeable Li-ion batteries, or 3.3–5.5V non-rechargeable batteries. A slide switch allows toggling between battery types, and the power rails to connected modules can be controlled programmatically by the WisBlock Core to optimize power consumption.

Modules are connected via high-speed board-to-board connectors, ensuring signal integrity and reliable communication. Modules are securely fastened with screws, making the setup vibration-resistant and dependable in industrial or mobile scenarios.

It also includes two user-defined LEDs, a power/charging indicator LED, and one user-defined push button, giving developers additional interaction and feedback tools.
