Using the iPhone 3Gs with a Mintyboost

UPDATED!

Pt 2530
If you’re using the iPhone 3Gs with a Mintyboost we have added a note to the FAQ that has the precise resistor setup you would want to use if you’re going to mod your kit.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. I’m looking at the official Apple hardware spec (NDA), and these resistor values and voltages are not correct. Close, though.

    Can’t you just crack open an official, certified Made for iPod charger and read the correct values off the SMT resistors? Then you’d have a single charger that works with EVERY model of iPod/iPhone. Even if you had just measured the voltages without taking it apart, you’d see that these values are wrong.

    I’m really surprised that no one has done this yet, while everyone speculates about what the resistors *might* be…

    This is a job fooor… Reverse Engineering!

  2. :/ huh! We did open up a ‘made for iPod/iPhone charger’ and read off the resistors. but we have another one we cannibalized and we’ll look at that one too!

  3. OK I destroyed an Apple USB charger and desoldered the 0402’s to get a precise measurement. Updated post with photos above.
    I’ll bet $ on these values 🙂
    Thanks for the feedback Mr. :/ Hopefully this is settled now!
