Now we have available is stock the uBitx case for Nextion Display 3.5 Inch And 5 Inch added to the existing case for 2.4 and 2.8 inch Nextion Displays.
This new case for builders who have some experience with soldering and willing to wire the set with instructions through some pictures and write ups.
The new case has a different design from the earlier one. The case is divided into two sections the first bottom cover has placement for speaker and lithium or Lipo Battery. The Lipo battery would be a better choice. For illustration purpose we have used a lithium battery. The battery can be secured on the case with suitable fitting. Since there are various batteries we did not make any particular fittings accessories for the case, we have left it for the builder to make according to his plans.
The power on off switch is mounted on the front panel, it is a rocker switch. The switch positions are as Top : Battery supply to tcvr Center: OFF Bottom position +12 Volts from external supply through DC socket.
