RakWireless RAK4260 LoRa Module


The RAK4260 WisDuo LPWAN Module is based on Microchip’s ATSAMR34J18B. It is a SiP device integrating a 32-bit ARM Cortex M0+ MCU with a LoRa Transceiver in a 15 millimeter x 15 millimeter compact package.

The SAMR chip provides a number of highly configurable peripherals (configurable as I2C/SPI/UART interfaces). There are 12-bit ADC in addition to the aforementioned.


  • Industry’s lowest power LoRa SiP device
  • 32-bit ARM Cortex M0+ MCU and LoRa Transceiver
  • Small form factor: 15 millimeter x 15 millimeter compact package
  • 256KB Flash and 40 KB RAM accommodates application code and stack
  • Most cost and size effective solution, eliminating need for external MCU
  • Fully supported 862 to 1020 MHz frequency coverage
  • Receive Sensitivity down to -148 dBm
  • Maximum Transmit Power up to 20 dBm
  • Low RX current of 17mA (typical)
  • LoRa Technology, (G)FSK, (G)MSK
