iLabs Challenger RP2040 LoRa (EU868)

  • FabrikantiLabs

Omschrijving

The Challenger RP2040 LoRa is an Arduino/CircuitPython compatible Adafruit Feather format microcontroller board based on the Raspberry Pi Pico (RP2040) chip.

The transceiver features a LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

LoRa

The integrated module LoRa module (RFM95W) can achieve a sensitivity of over -148 dBm utilizing a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.

The RFM95W is connected to the RP2040 via SPI channel 1 and a few GPIO’s that is required for signaling. A U.FL connector is used to attach your LoRa antenna to the board.

  • 168 dB maximum link budget
  • +20 dBm – 100 mW constant RF output vs. V supply
  • +14 dBm high efficiency PA
  • Programmable bit rate up to 300 kbps
  • High sensitivity: down to -148 dBm
  • Bullet-proof front end: IIP3 = -12.5 dBm
  • Excellent blocking immunity
  • Low RX current of 10.3 mA, 200 nA register retention
  • Fully integrated synthesizer with a resolution of 61 Hz
  • FSK, GFSK, MSK, GMSK, LoRaTM and OOK modulation
  • Built-in bit synchronizer for clock recovery
  • Preamble detection
  • 127 dB Dynamic Range RSSI
  • Automatic RF Sense and CAD with ultra-fast AFC
  • Packet engine up to 256 bytes with CRC
