This is Pi Zero 2 W with Pre-Soldered Color-Coded Header. At the heart of RPi Zero 2 W is RP3A0, a custom-built system-in-package designed by RPi 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 predecessor RPi 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. ^^ Broadcom BCM2710A1, 1GHz quad-core 64-bit Arm Cortex-A53 CPU.
512MB LPDDR2 SDRAM. ^^ 2.4GH z 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, Micro USB power. HAT-compatible 40-pin header footprint (unpopulated). ^^ H. 264, MPEG-4 decode (1080p30); H. 264 encode (1080p30); OpenGL ES 1.1, 2.0 graphics.
