Questions and Answers

  • Question: Hello, What is the difference between the pcb version 3B and 3C ? I have recently bought 2 pcb of the 3b version...

    Posted by G***o (2) - 20/03/2019 20:37:03

    Answer: They are almost the same, 3C has a header for ESP8266 module, 3B also has a header but need wiring between header and AY pins. ESP8266 is an option, no any propgram to support it yet.

  • Question: Is there a kit version? What about the 3C PCB version?

    Posted by f***s (0) - 09/03/2019 20:54:47

    Answer: Right now I ship with 3C version, no more 3B. You can buy a Kit for $99.00, just buy this one and wait for me to send an invoice before make a payment.

  • Question: Do I need to provide my own rom or dose it come with a ROM?

    Posted by t***4 (1) - 08/09/2018 15:59:45

    Answer: It comse with ROM, ready to use
