RAK19015 WisBlock Battery Power Slot Module Datasheet
Overview
Description
The RAK19015 WisBlock Battery Power Slot Module is a power board that comprises a battery connector, a reset push button, and two LEDs. It is designed to be used with WisBlock Base Board with Power Slot via the 40-pin WisBlock connector.
RAK19015 is optimized to support very low-power applications since it only has a Li-Ion battery and 3.3 V switching regulator in the circuit removing unnecessary components that consume extra current consumption.
Features
- Designed for battery-only powered applications
- High-efficiency switching regulator
- Optimized for low-power devices
- Module size: 30 x 20 mm

Overview
Board Overview
Figure 4535: RAK19015 WisBlock Power Module top (left) and bottom (right) viewMounting
The RAK19015 module can be mounted on the Power slot of the WisBlock Base board. Figure 2 shows the mounting mechanism of the RAK19015 on a WisBlock Base module, such as the RAK19010.

The hardware specification discusses the pinouts and their corresponding functions and diagrams of the module. It also covers the electrical and mechanical characteristics that include the tabular data of the functionalities and standard values of the RAK19015 WisBlock Battery Power Slot Module.
Interfaces
RAK19015 WisBlock Battery Power Slot Module provides the following interfaces, headers, a button, and WisConnectors:
- 1 WisBlock Power module
- 2 pin battery interface
- 2 LEDs
- 1 Reset button
RAK19015 doesn't have a USB connector, so when RAK19015 and RAK19010 are used together, it is not possible to program the core (unless you use Jlink). If you want to program the core, you need the RAK5804. Then you can supply over RAK19015 and program over RAK5804.

Figure 4 shows the battery connector V+(VBAT) and V-(GND).
Figure 4538: Battery Connector Pin OrderThe voltage of the battery must not exceed 4.3 V.
LEDs
Two LEDs are used to indicate the operating status. Below are the functions of the LEDs:
- 🟢 Green LED - Connected to the MCU module, controlled by MCU defined by the user.
- 🔵 Blue LED - Connected to the MCU module, controlled by MCU defined by the user.
RESET Push Button
The Reset Push Button is shown in Figure 3 and is connected to the MCU module. When pushed, it resets the MCU.
Pin Definition
The RAK19015 Battery Power Slot Module has a 40-pin WisConnector that is compatible with the WisBlock Power Slot. The pin order of the connector and the pinout definition is shown in Figure 5.
VBAT, 3V3, RESET, LED1, LED2, and GND are connected to the WisBlock IO connector.
