"you can now get the 1.4GHz clock speed, 5GHz wireless networking and improved thermals of Raspberry Pi 3B+ in a smaller form factor, and at the smaller price of $25. Meet the Raspberry Pi 3 Model A+."
with Raspberry Pi 3 Model B+ shipping in volume, we’re able to fill that gap by releasing Raspberry Pi 3 Model A+. Raspberry Pi 3 Model A+ incorporates most of the neat enhancements we made to its big brother, and features:
- A 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU
- 512MB LPDDR2 SDRAM (vs. 1024 of 3 B+)
- Dual-band 802.11ac wireless LAN and Bluetooth 4.2/BLE
- Improved USB mass-storage booting
- Improved thermal management"
