It had a sealed non-replaceable rechargeable Lithium-ion battery which is charged via a Lightning port on the rear of the keyboard.

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.

At the same time, the Magic Keyboard without the numeric keypad (A1644) received a minor visual update with new Control and Option key symbols.

A space gray Magic Keyboard with Numeric Keypad with black keys was bundled with the iMac Pro[3] and later made available for standalone purchase.

Using this new design, two additional model options also include Touch ID sensors in place of the lock key.

The Magic Keyboard with Touch ID and Numeric Keypad (A2520) was available initially only in silver with white keys.
