Finally I made my own gamebuino after second attempt. Firstable I'd made it on DIP version 328p, which has not ADC6,7 and LCD which not worked less 5 volts. Now it works fine, but I have some problems with settings, sometimes some values is corrupts. I've made some changes in original schematics: LP2590/3.3 as voltage regulator and TP4056 as charger.
