the capacitor should have as low as possible ESR (tantalum?) jaky esr maji ty keramiky, co tam mam ja the diode has to have as low as possible reverse current leakage

ltc6101 ltc6103 ltc6104? INA199?

bacha ina21x ma jiny footprint (sc70) nez jsem pouzil v prvni verzi. !!

Sound processing

Todo

presunout servo vstupy na PB0 - PB4 rozchodit adc na PA0 - PAx
