If you are interested in buying a project that shows "SOLD OUT", You can contact me anyway.

Especially for you, I can arrange the production of such device under the following conditions: The device will be delivered as a DIY kit, not assembled and finished device. Kit contains PCB and all components, not soldered. The minimum quantity taken for PCBs shall be 5pcs (smaller quantities cannot be produced), set of components is sufficient in 1pc. In any case, initial consultation is required, some parts are no longer available!
