1 thinknode G1 for testing and we are interested in using it for LTE 4G connectivity, what do I need to do?
The customized version of the 4G module is soldered directly to the PCB and cannot be purchased separately or installed on the standard version. However, we are happy to help you enable LTE functionality in ThinkNode G1 through bulk ordering and customization to suit your needs.
