It was compatible with Macs running OS X El Capitan and later, iPhones and iPads running iOS 9 or later, and TVs running Apple TV Software 7.0 or tvOS 10 or later. It used an ST Microelectronics STM32F103VB 72 MHz 32-bit RISC ARM Cortex-M3 processor and included the Broadcom BCM20733 Enhanced Data Rate Bluetooth 3.0 Single-Chip Solution. The rechargeable battery lasted one month between charges. It had a sealed non-replaceable rechargeable Lithium-ion battery which is charged via a Lightning port on the rear of the keyboard.
