It is powered by a rechargeable 3.82 V, 0.329 Wh lithium-ion battery. The Apple Pencil uses an STMicroelectronics STM32L151UCY6 Ultra-low-power 32-bit RISC ARM-based Cortex-M3 MCU running at 32 MHz with 64 KB of flash memory, a Bosch Sensortech BMA280 3‐axis accelerometer and a Cambridge Silicon Radio ( Qualcomm) CSR1012A05 Bluetooth Smart IC for its Bluetooth connection to the iPad. It also ships with a female-to-female Lightning adapter that allows it to be used with charging cables. The initial charge lasts about twelve hours, but fifteen seconds of charging provides sufficient power for 30 minutes of use. One end of the device has a magnetically-fastened removable cap which covers a Lightning connector which is used for charging from an iPad's Lightning port. The Pencil and the user's fingers can be used simultaneously while rejecting input from the user's palm. The Apple Pencil has pressure sensitivity and angle detection, and it was designed for low latency to enable smooth marking on the screen. It uses a magnetic connector on the side of the tablet for charging rather than a Lightning connector, and includes touch-sensitive areas that can be tapped to perform actions within supported apps.Īpple has promoted the Pencil as being oriented towards creative work and productivity during its unveiling, the Pencil's drawing capabilities were demonstrated using the mobile version of Adobe Photoshop, and its document-annotation capabilities were shown on several Microsoft Office apps. The second-generation Apple Pencil was announced on October 30, 2018, alongside the third-generation iPad Pro, and is used with most iPad models that contain a USB-C port (excluding the tenth-generation iPad). The Pencil is compatible with the first- and second-generation iPad Pro models, and the sixth through tenth-generation iPad models (with the latter requiring a USB-C adapter). It communicates wirelessly via Bluetooth and has a removable cap that conceals a Lightning connector used for charging. The first-generation Apple Pencil was announced alongside the first iPad Pro on September 9, 2015.
