RAK2247 As described in Figure 3, the RAK2247 card integrates one SX1301 chip and two SX1255/7 and other chip for RF signal, which represents the core of the device, providing the related LoRa modem and processing functional lilies. Additional signal conditioning circuitry is implemented for PCI Express Mini Card compliance, and one UFL connectors are available for external antennas integration. 2.2 Operating Frequencies The board supports all LoRaWAN frequency channels as below.

The voltage must be stable, because during this operation the current drawn from 3.3Vaux can vary significantly, based on the power consumption profile of the SX1301 chip (see SX1301 DS). 2.
RAK2247 RESET 2.8 RAK2247 card includes the RESET active-high input signal to reset the radio operations as specified by the SX1301 Specification. Antenna RF Interface 2.9 The modules have one RF interfaces over a standard UFL connectors (Hirose U. FL-R-SMT) with a characteristic impedance of 50OHM. The RF port (J1) supports both Tx and Rx, providing the antenna interface. 2.
RAK2247 The product is not protected against overvoltage or reversed voltages. If necessary, voltage spikes exceeding the power supply voltage specification, given in table above, must be limited to values within the specified boundaries by using appropriate protection devices. 2.10.
