Page 9: Power Supply
2247 Power Supply RAK2247 card must be supplied through the 3.3Vaux pins by a DC power supply. 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). -
Page 10: Antenna Rf Interface
2247 Antenna RF Interface 2.11 The modules have one RF interfaces over a standard UFL connectors (Hirose U. FL-R- SMT) with a characteristic impedance of 50Ω. The RF port (J1) supports both Tx and Rx, providing the antenna interface. Electrical Characteristics 2.12 Stressing the device above one or more of the ratings listed in the Absolute Maximum Rating section may cause permanent damage. -
