PiTFT works with Raspberry Pi B+ . We have updated our kernel deb files & tutorial to be B+ compliant! The PiTFT resistive and capacitive work just fine on a B+ too! As the GPIO header moved down on the B+, the TFT now overhangs by 5mm. Adventurous makers can cut this unused section of PCB off or leave as is!
We will be working to make a PiTFT HAT but there’s no ETA!
