  Hi OP,
  I'm thinking of buying about 40-50 units of the 5110 lcd unit. They used to cost $270 each back in 98. I recently bought myself a time machine on ebay last week and want to make a lot of money now.

  Please give me your best price
  Thanks

    for $270 did they come with a free phone?

    Wow, Nokia must have had lots of leftovers because they couldn't match the Shanzhai phone makers.

  Hi OP,

  The step-down power supply module is it's output 12V or 5V because the description on your web-page says:

  Output volt:5V
  output current:1.5A(MAX)

    If they are using the 7812 voltage regulator chip then the description is wrong. Supporting evidence is that the min input voltage is 14.5V which gives the regulator enough working margin.

      I don't know if that's true, but have a +1 for putting it in such an eloquent manner that I believe it to be so.

      Yeah, the item title, closeup photos and parts listing show a 7812 but the description's output voltage implies a 7805. I'd say it's just a bit of bad copy in the description's output voltage. That's known to happen in icstation listings.

      You could just replace the 7812 in this kit with a 7805 if you want 5V. Just don't put the 7812's max input voltage across one though :)

      For comparison, the 7812 alone from Altronics/Jaycar is about a dollar forty/fifty.

    Be aware that this voltage regulator works by dissipating the difference as heat so if the current is large the heatsink will get hot.

  What on earth are these for???

    Electronics tinkerers. Arduino, Raspberry Pi, Beagle Bone, that kind of mob.

    Getting a regulated 12V off a 24V circuit. I used to use the 5V ones in my car a long time ago.
