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.
