RAK19003 WisBlock Mini Base Board

Thank you for choosing RAK19003 WisBlock Mini Base Board in your awesome IoT Project! 🎉 To help you get started, we have provided you with all the necessary documentation for your product.

Product Description​

RAK19003 is a WisBlock Base board that connects WisBlock Core and WisBlock Modules. It provides the power supply and interconnection to the modules attached to it. It has one slot reserved for the WisBlock Core module and two Slot C-D for WisBlock Modules. The WisBlock Core is attached on the top side, and the WisBlock Modules are attached to the bottom side of the RAK19003 WisBlock Base board. Slot D holds modules up to 23 mm in size, while Slot C supports 10 mm WisBlock Modules. Also, there are two 2.54 mm pitch headers for extension interface with BOOT, I2C, and UART pins.

For convenience, there is a Type-C USB connector that is connected directly to WisBlock Core MCU’s USB port (if supported) or to a USB-UART converter depending on the WisBlock Core. It can be used for uploading firmware or serial communication. The USB-C connector is also used as a battery charging port.

WisBlock Modules are connected to the RAK19003 WisBlock Base board via high-speed board to board connectors. They provide secure and reliable interconnection to ensure the signal integrity of each data bus. A set of screws are used for fixing the modules, which makes it reliable even in an environment with lots of vibrations.

Using RAK19003 as your WisBlock Base board, you can make your project compact, which is ideal in small enclosures. You can also use a RAK19005 WisBlock Sensor Extension Cable to position WisBlock Modules apart from the WisBlock Base board or in any part of your case. RAK19003 has connectors for the following:

  • 1 WisBlock Core module
  • 2 WisBlock Modules compatible with Slot C-D
  • 1 Type-C USB port for programming and debugging
  • 3.7 V Rechargeable battery connector
  • 5 V Solar Panel connector
  • 2 Headers with BOOT, I2C, and UART pins accessible with solder contacts

Additionally, it has two user-definable LEDs - one power supply/charging indicator LED and a reset button.

Product Features​

  • Power supply

    • Supports both 5 V USB and 3.7 V rechargeable battery as power supply.
    • Has a connector for a 5 V solar panel to recharge the battery in a remote solution.

    • Has an electronic load switch to power the WisBlock modules. The power supply for the WisBlock modules boards can be controlled by the WisBlock Core modules application.

  • Size

    • A compact size of 30 x 35 mm, which lets you create solutions that fit into smallest housings.

Prerequisites​

WisBlock Mini Base is amazingly easy to use and requires only a Type-C USB cable to start developing with the system.

warning
  • Only 3.7-4.2 V Rechargeable Li-Ion batteries are supported. Do not use other types of batteries with the system.
  • Only 5 V solar panels are supported. Do not use 12 V solar panels. It will destroy the charging unit and eventually other electronic parts.
