ITead mystery PCB: TFT digital picture frame by Erick Aubin

Posted on Saturday, December 31st, 2011 in documentation by DP

Arhi received a mystery PCB with his last ITead PCB order:

TFT digital picture frame with in built Real-Time clock and thermometer
Designed by: Erick Aubin

I assume B1 is a big capacitor, something like 22000uF or similar (judging from the size), USB-BUB is some ft232 or similar usb 2 uart board, x1 is some 8 or 16 MHz xtal and X2 is 32768 kHz, U1 is probably some ATMEGA as J1 looks like AVR ICSP connector and Z1 is some 7805 or something … now, what mega should be there, what firmware, what kind of tft lcd … no idea … if you know a homepage for this project – share :D

    I think maybe B1 is a battery? looks really huge for a cap.

      Yeah, ‘B’ is fairly common to refer to Battery voltage, e.g., B+ and B- for the power rails, so it should not be surprising as a component designation.

      Yes the footprint fits both 2xAA(A) or 1x9V battery holder ..
      USB-BUB is some “standard” FT232R board (~$14), Z1 is some 780x in TO220 (not smd) package (tab is too far away) so the tab is GND not output

    I’ve been looking at some sites, but did not get any info about this board. really a mysterious gift

    I´ve seen it at the 28c3 in Berlin this year, I guess :)
