hmmm, do you have Intelligent or Enhanced display they had in back in other end extension connector and in othe end TX,RX,+5v,GND connector. You need to connect power on +5 and GND. UPS to Serial converter or power from Arduino or ESP/NodeMCU board not give enouhg power so if connecting to USP for probramming connect bard with other cable and Display with other USB cable+adapter. then Display RX to board TX and Display TX to board RX.
see https://nextion.tech/intelligent-series-introduction/ in the end of page it has picture and left side is the power / RXTX connector. Also in following page https://nextion.tech/intelligent-series-introduction/ there is table and in the table row Pictures you see power and TXRX connector cable that should come with display
Thanks
Firstly, great work! Do you know the wiring for these displays? My K nextion doesnt have any printed labels on the 40pins it has.
