The frequency is software-configurable for your region's ISM band. LoRa modulation delivers over 2 km range line-of-sight with default settings, and up to 20 km with optimised configurations and directional antennas.\n\nThe RP2040's dual cores and 264 KB RAM make it well-suited for running LoRa and LoRaWAN stacks that require significant processing power for packet management. The board includes a STEMMA QT connector and a uFL connector for attaching larger external antennas.\n\nKey Features\n\n\nRP2040 Processor – Dual ARM Cortex M0+ cores at ~133 MHz, 3.3V logic\n\n264 KB SRAM + 8 MB SPI Flash – For code and file storage\n\nRFM95 LoRa 868/915 MHz Radio – SX1276-based LoRa transceiver with SPI interface, software-tuneable frequency\n\n+5 to +20 dBm Output – Up to 100 mW transmit power, selectable in software\n\n2+ km Range – Line-of-sight with default settings; up to 20 km with optimisation\n\nUltra-Low Power Radio – ~300 µA full sleep, ~120 mA peak transmit (+20 dBm), ~40 mA active listening\n\nuFL Antenna Connector – For attaching external SMA antennas (or solder a wire antenna)\n\nUSB Type C – Native USB with UF2 bootloader\n\nSTEMMA QT / Qwiic – On-board I2C connector for solderless sensor connections\n\nNeoPixel – On-board RGB LED for status feedback\n\n21 GPIO Pins – 4× 12-bit ADC, 16× PWM, 2× I2C, 2× SPI, 2× UART\n\nLiPo Battery Support – JST connector with built-in 200 mA+ charger\n\nCompact Design – 50.8 mm × 22.8 mm × 7 mm, weighing 6.3 g\n\n\nAlso Available\n\n\nFeather RP2040 RFM69 868/915 MHz – Packet radio (shorter range, higher data rate)\n\nFeather RP2040 – Base model\n\nFeather RP2040 Adalogger – With MicroSD card slot\n\nFeather RP2040 SCORPIO – 8-channel NeoPixel driver\n\nFeather RP2040 USB Type A Host – With USB host port\n\nFeather RP2040 DVI – With HDMI-compatible DVI output\n\n\nIdeal For\n\nLong-range wireless sensor networks\nRemote environmental monitoring\nBattery-powered IoT nodes requiring kilometre-scale range\nLoRaWAN gateway and node applications\n\n\nPackage Contents\n\n1× Feather RP2040 RFM95 LoRa 915 MHz\n1× Header pin set\n\n\n\nNote: A wire antenna must be soldered to the board, or use a uFL-to-SMA adapter with an external 900 MHz antenna (not included).
