Overview
There are six (6) slots on RAK5005-O WisBlock Base. The CPU SLOT is reserved for the WisBLock Core module, which has the main MCU. The IO SLOT is used for IO extension, for example, RS485 module, 4-20 mA/0-5 V module, Wireless modules. SLOT A, SLOT B, SLOT C, and SLOT D are used to connect with the I2C module, while SLOT A can be used for the GPS board too. Also, there are 2.54 mm pitch connectors for extension interface, such as I2C, UART, and GPIO pins.
Figure 1: RAK5005-O Top and Bottom ViewFor convenience, there is a USB connector for debugging. It is directly linked to the MCU’s USB port (if supported). You can access the internal MCU by connecting to a computer’s USB port directly. This USB connector is also used as a battery charging port.
Each module has a method designed to connect and fasten the module easily. These connectors are high-speed board-to-board connectors, they provide signal integrity for each data bus. A set of screws are used for attaching the module under the environment with vibrations.
To avoid electromagnetic and heating interferences, the sensor connectors on the WisBlock Base are designed to be installed on both sides of the PCB. Also, a sensor module can be attached either on the top layer or the bottom layer of the WisBlock Base board.
Figure 1: Bottom view of the board with interfacesFor example, it is recommended to attach a temperature sensor outside of the base board, as shown in Figure 6. It allows getting more accurate measurements since the the heating introduced by other modules could interfere with the temperature sensor located on the top layer of the base board.
