Apple Pencil Technical Specification

What technology does Apple pencil use?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.

What is the difference between 1st and 2nd generation Apple pencil?The original Apple Pencil has a cap on the end covering its Lighting connector. … The second generation Apple Pencil doesn’t have a cap, and has a flat side instead of a completely round shaft. That flat side snaps in place on the edge of your iPad Pro.

How many levels of pressure sensitivity does the Apple pencil have?4,096 levelsApple Pencil: Unspecified pressure sensitivity, 20ms latency, tilt support, 12 hours battery life (rechargeable), Bluetooth 4. Surface Pen: 4,096 levels of pressure sensitivity, 21ms latency, tilt/rotation support (on some devices), 9g of activation force, 1 year battery life (replaceable), Bluetooth 4


Apple Pencil expands the power of iPad mini, iPad Air and iPad, and opens up new creative possibilities. It’s sensitive to pressure and tilt so you can easily vary line weight, create subtle shading and produce a wide range of artistic effects — just like a conventional pencil, but with pixel-perfect precision.
