*Supported bands depends of the model. 3 Interfaces RAK5146 Interfaces are listed below:
Power Supply - The RAK5146 concentrator module must be supplied through the 3.3Vaux pins by a DC power supply. The voltage needs to be stable since the current drawn can vary significantly during operation based on the power consumption profile of the SX1303 chip (for more information, see the SX1303 Datasheet (opens new window)). SPI Interface - SPI interface mainly provides for the Host_SCK, Host_MISO, Host_MOSI, Host_CSN pins of the system connector. The SPI interface gives access to the configuration register of SX1303 via a synchronous full-duplex protocol. Only the slave side is implemented. USB Interface - The USB interface mainly provides for the USB_D+, USB_D- pins of the system connector. The USB interface gives access to the configuration register of SX1303 via an MCU STM32L412KBU6. Only the slave side is implemented. UART and I2C Interface - RAK5146 integrates a ZOE-M8Q GPS module which has UART and I2C interface. The PINs on the golden finger provide a UART connection and an I2C connection, which allows direct access to the GPS module. The PPS signal is not only connected to SX1303 internally but also connected to the golden finger which can be used by the host board. GPS_PPS - RAK5146 includes the GPS_PPS input for received packets time-stamped and Fine timestamp. RESET - RAK5146 SPI card includes the RESET active-high input signal to reset the radio operations as specified by the SX1303 Specification. RAK5146 USB cards RESET is controlled by MCU. Antenna RF Interface - The module have one RF interface over a standard UFL connector (Hirose U. FL-R-
SMT) with a characteristic impedance of 50. The RF port (J1) supports both Tx and Rx, providing the antenna interface Notes:
Do not power the module without connected antenna/s. This may damage the radios. 4 Electrical requirements ELECTRICAL REQUIREMENTS Stressing the device above one or more of the ratings listed in the Absolute Maximum Rating section may cause permanent damage. These are stress ratings only. Operating the module at these or any conditions other than those specified in the Operating Conditions sections of the specification should be avoided. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. The operating condition range defines those limits within which the functionality of the device is guaranteed. Where application information is given, it is advisory only and does not form part of the specification. ABSOLUTE MAXIMUM RATING The limiting values given below are following the Absolute Maximum Rating System (IEC 134).

This module must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times. POWER CONSUMPTION POWER SUPPLY RANGE Input voltage at 3.3Vaux must be above the normal operating range minimum limit to switch on the module.
