The L04 is the LoPy4 OEM module. It works just like the LoPy4 but we’ve trimmed a few bits to make it super easy to integrate. Quadruple network module: WiFi, Bluetooth, LoRa and Sigfox.

• Powerful CPU, BLE and state of the art WiFi radio
• Can also double up as Nano LoRa gateway
• MicroPython enabled
• Fits on the Pycom OEM Reference Board
• Ultra-low power usage: a fraction compared to other connected micro controllers

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

Operating Frequencies :

• RCZ1  868MHz (Europe)
