RAKwireless RAK19007 WisBlock Base Board 2nd Generation, USB-C, LoRa/IoT

Product detailed description

RAKwireless RAK19007 is the base board of the second generation WisBlock modular system, which can be equipped with a WisBlock Core processor module, a WisBlock IO expansion module, and up to four WisBlock Sensor modules. The board manages the power supply and interconnection of all installed modules – it can be powered via USB-C, a Li-Ion battery, or a solar panel, with an integrated charger that handles battery recharging automatically. Compared to the previous RAK5005-O generation, it features a USB-C connector, an improved voltage regulator, and a relocated slot D, which accommodates a GNSS module without sacrificing another sensor slot. With dimensions of only 30 × 60 mm and a quiescent current consumption in the microampere range, it is ideal for battery-powered IoT nodes, LoRaWAN sensors, and Meshtastic network builds.

Package contents:

• 1× RAK19007 base board
• 1× USB cable
• 15× M1.2 × 3 screws
• 5× M2.5 × 4 screws

Note:

• The board on its own is not a functional device – it requires at least one WisBlock Core module.
• Connect only rechargeable Li-Ion batteries; the board does not have a charging profile for LiFePO4 or NiMH, and non-rechargeable batteries must not be connected.
• The battery voltage must not exceed 4.3 V and the solar panel voltage 5.5 V, otherwise there is a risk of permanent damage to the board.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
