NOTE
The RAK19001, as any electronic equipment, is sensitive to electrostatic discharge (ESD). Improper
handling can cause permanent damage to the module.
Current Consumption
The RAK19001 is designed for low-power IoT products. Its power supply uses a high-efficiency low ground
current regulator. When there is no module on RAK19001, the leakage current is lower than 2 µA. With
WisBlock Core and WisBlock sensor on it, the sleep current is lower than 10 µA. When a LoRa module is
transmitting, the current may reach 130 mA.
Rechargeable Battery Connector
The RAK19001 WisBlock Base Board can be powered by a rechargeable battery connected to the P1 connector.
The nominal operating voltage of the battery should be within the range shown in the following table. The matching
connector for the battery wires is an
If a rechargeable battery is used, the USB connector is used as a charging port. The voltage and current fed to the
battery through the port should not exceed its charging limits, as shown in the table below.
