파이콤 LoPy4 IoT 플랫폼 - WiFi, BLE, LoRa, and Sigfox
(Pycom LoPy4 - WiFi, BLE, LoRa, and Sigfox)
개요
- 파이콤 LoPy4는 WiFi, BLE, LoRa, SigFox를 지원하는 IoT 플랫폼입니다.
- MicroPython 을 지원하는 OS가 내장된 마이크로컨트롤러 입니다.
- LoRa/SigFox 통신시에 안테나 없이 사용하면 제품이 손상될 수 있습니다.
- 안테나는 다음 제품을 검토하십시오.
- 900Mhz LoRa 안테나 키트 (900Mhz Antenna Kit - For LoPy, LoRa, etc)
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 25uASigfox Operating Frequencies
