Overview
The nXPico W is the WiFi-equipped variant of nXPico: same RP2350A hardware and I/O, plus an onboard 2.4 GHz WiFi radio module. It runs neXo’s CODESYS Control pico runtime. Login, download and monitoring go over USB (COM1), as on nXPico. WiFi can be used to:
- use the built-in CODESYS SysSocket library
- use the custom library for managing X.509 certificates
- use the custom library for MQTT/MQTTS
