At the heart of Raspberry Pi Zero 2 W is RP3A0, a custom-built system-in-package designed by Raspberry Pi in the UK. With a quad-core 64-bit ARM Cortex-A53 processor clocked at 1GHz and 512MB of SDRAM, Zero 2 is up to five times as fast as the original Raspberry Pi Zero. As for heat dissipation concern, Zero 2 W uses thick internal copper layers to conduct heat away from the processor, sustaining higher performance without higher temperature.

Key features include:

• Broadcom BCM2710A1, 1GHz quad-core 64-bit Arm Cortex-A53 CPU

• 512MB LPDDR2 SDRAM

• 2.4GHz 802.11 b/g/n wireless LAN

• Bluetooth 4.2, Bluetooth Low Energy (BLE), onboard antenna

• Mini HDMI port and micro USB On-The-Go (OTG) port

• microSD card slot

• CSI-2 camera connector

• HAT-compatible 40-pin header footprint (unpopulated)

• Micro USB power

• Composite video and reset pins via solder test points

• H.264, MPEG-4 decode (1080p30); H.264 encode (1080p30)

• OpenGL ES 1.1, 2.0 graphics
