The Apple A4 discussion kicked off in earnest when Steve Jobs introduced the iPad on January 27. In an infamous series of slides tracing the roots of Apple back to the two Steves in his garage, Jobs introduced the Apple A4 processor that powers the iPad, operating at a clock frequency of 1GHz.
The first question was whether the A4 could be the first offspring spawned by Apple’s April 2008 acquisition of PA Semi. However, it seemed there was not enough time for a brand new design. Jon Stokes provided an interesting early insight into the CPU-GPU combination and the potential role of PA Semi.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
