Unboxing SIO2SD Micro by Panos Santos

SIO2SD Micro (testing)

Autopsy:

L’interfaccia SIO2SD Micro per Atari 8-bit Atari XL / XE è un dispositivo che consente di caricare i giochi e applicazioni da schede di memoria SD. L’interfaccia viene connessa tramite il connettore SIO (Serial Input/Output) dell’Atari.

Questa versione è come la SIO2SD originale e si basa sull’ultimo schema disponibile la “versione 2″, l’interfaccia si presenta in una forma più piccola e con alcuni miglioramenti di Panos.

Panos improvements:

  • As for the cpu the latest “low consumption” ATMega32A microcontroller in smd form.
  • The 74LVC245 who guarantees good data transfer between the microcontroller and SDcard, in proper voltage levels also.
  • New 47nf capacitors for better button response.
  • Extra resistor and capacitor added in output of low dropout voltage regulator, for better voltage stability particularly at “no load” condition. As result of that is much higher reliability and compatibility with more SD cards.
  • New tactile switches with smooth feeling for more comfortable use.
  • Push on-Push off type SD connector.
