The RAK19009 is a compact WisBlock Base Board designed to connect a WisBlock Core module, a Power module, and up to two WisBlock I/O modules. It features dedicated slots for the Core and Power modules on the top side, and two slots (C and D) on the bottom for I/O modules—Slot C supports modules up to 23 mm, while Slot D supports modules up to 10 mm. High-speed board-to-board connectors ensure reliable, low-noise connections, and the modules are securely fixed with screws for stability even in high-vibration environments. The board also includes two 2.54 mm headers providing access to BOOT, I2C, and UART pins. Its compact form factor makes it ideal for small enclosures, and it supports flexible module placement using the RAK19005 Sensor Extension Cable. The RAK19012 WisBlock USB LiPo Solar Power Slot Module is a versatile power board designed for WisBlock systems. It features a USB-C connector for debugging and firmware uploads, a battery connector with an onboard charger, and a solar panel input for alternative power. It also includes an LED charge status indicator, two user-configurable LEDs, a reset button, and a power connector for linking to the WisBlock Base board. This module offers flexible power options and essential functions in a compact form factor, ideal for low-power and solar-powered IoT applications. 1.show the mounting holes location and diameter of the RAK19009 Board 2.RAK19012 WisBlock Power Module top (left) and bottom (right) view Features: USB-C Connector for easy programming and debugging of the WisBlock Core LiPo Battery Support with onboard charging functionality Solar Panel Input for efficient battery charging from solar energy Integrated Charger Chip ensures safe and reliable battery management LED Indicators for charging status and two user-configurable LEDs Modular Design allows flexible expansion and integration with other WisBlock modules High-Speed Connectors ensure signal integrity with WisBlock Base boards Supports Multiple Low-Power MCUs for energy-efficient solutions Sensor Compatibility with up to two different types of sensors on one board Compact Size (30 x 37 mm) ideal for tight enclosures and space-limited projects Applications: Wireless Sensor Network Environmental monitoring Wireless data transmission Data acquisition in the industrial environment Location and tracking of personnel or moving objects Package Includes: 1 x RakWireless WisBlock Base
