Core framework, dashboard and modbus, mqtt and eKuiper pluggable modules are open source under LGPLv3 license. Neuron could run with these modules without a license installed. A valid trial or official EMQ license must be installed if you need any one or more of the commercial modules as mentioned above.
A trial EMQ license can be download from our official website https://www.emqx.com/en/apply-licenses/neuron. All available modules could be used with limitation on 100 connections and 1000 data tags for 15 days.
