Pycom LoPy4

With the LoPy4 from Pycom you have a small MicroPython based IoT development platform with WiFi, Bluetooth, Sigfox and LoRa. With a Wi-Fi range up to 1km in combination with the ESP32 Wi-Fi chip from Espressif offers many possibilities for IoT applications.
With the Python API you can access all hardware via Python scripts that you can place on this board. These functions are extended and improved by updates that are provided by Pycom.

Features:

• Based on Espressif ESP32 chip (dual-core with Wi-Fi and Bluetooth)
• Up to 1km Wi-Fi range
• Use of MicroPython (slim version of Python)
• Fits on a breadboard
• Connection between external or internal antenna possible from MicroPython script
• Low energy consumption
• Processor 1 for network and IPv6 stack
• Processor 2 for own code
