RAKwireless Dual IO Base Board with Power Slot RAK19011

The RAK19011 base board itself does not include a power regulator. You must pair it with a separate WisBlock Power Board (e.g., RAK19007 for battery, RAK19003 for USB). This Power Board connects to the designated slot and provides the 3.3V or 5V to the system, supporting sources like USB-C, Li-Ion batteries, solar panels with MPPT, 5-24V DC inputs, or Power-over-Ethernet, offering extreme flexibility for field deployments.

The board accepts standard WisBlock form-factor modules. The single Core slot hosts MCU boards like the RAK4631 (nRF52840 + SX1262) or RAK3172 (STM32WLE5). The two IO slots are for communication modules such as LoRa (RAK5860), Cellular (RAK5860), or BLE. The six sensor slots support various I2C-based environmental, inertial, and analog sensors from the WisBlock Sensor series, allowing for rapid hardware configuration.

Security is achieved through power isolation. By using a separate Power Board that can be physically disconnected or toggled, you can cut power to the Core MCU slot. This prevents unauthorized firmware flashing via the USB port on the Core module, as the MCU requires power to enter bootloader mode. It's a hardware-level protection method crucial for industrial devices deployed in inaccessible or secure locations.

Yes, it is an excellent platform for solar-powered nodes. Combine the RAK19011 with a WisBlock Power Board that supports solar input with battery management (like the RAK19007), a low-power Core module (e.g., RAK3172), a LoRa IO module (e.g., RAK13300 for 868MHz), and your required sensors. The modular design lets you optimize power management and communication for long-term, energy-harvesting deployments in agriculture or remote monitoring.
