7146 RS232/485/422 To WIFI adopts the latest WIFI chipset,
which has stronger WIFI performance and higher cost performance. Use ARM M4 kernel, main frequency 192MHz, and use real-time operating system. The ZLAN7146-5 supports connecting WIFI hotspots of 5.8G (currently both of them are 2.4G frequency bands in AP mode), and others are similar to 7146.
7146 supports one RS232/485/422 to WIFI, can be as a STA or AP mode. There is no Ethernet interface (RJ45 is for future extended use). Support Modbus TCP to RTU, support sending heartbeat packets, registering packages and transcoding scripts.
