파이콤 LoPy4 IoT 플랫폼 - WiFi, BLE, LoRa, and Sigfox

(Pycom LoPy4 - WiFi, BLE, LoRa, and Sigfox)

개요

특징

  • Powerful CPU, BLE and state of the art WiFi radio
  • Can also double up as Nano LoRa gateway
  • MicroPython enabled
  • Fits in a standard breadboard (with headers)
  • Ultra-low power usage
  • LoPy4 includes 2 years of Sigfox connectivity.
  • Note: If you want to connect LoPy4 via USB to your computer, you will also need either the Expansion Board 2.0, Pysense or Pytrack.
  • Processing

    – Espressif ESP32 chipset
    – Dual processor + WiFi radio System on chip
    – Network processor handles the WiFi connectivity and the IPv6 stack
    – Main processor is entirely free to run the user application
    – An extra ULP-coprocessor that can monitor GPIOs, the ADC channels and control most of the internal peripherals during deep-sleep mode while only consuming 25uA
