Overview
- By halving the RAM to 512MB, and removing the USB hub and Ethernet controller, Raspberry Pi 3 Model A+ is able to become smaller in size, and hit a lower price point. 
- Raspberry Pi 3 Model A+ incorporates most of the neat enhancements as its big brother Raspberry Pi 3B+ 
Features:
- A 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU 
- 512MB LPDDR2 SDRAM 
- Dual-band 802.11ac wireless LAN and Bluetooth 4.2/BLE 
- Improved USB mass-storage booting 
- Improved thermal management 
Like its big brother, the entire board is certified as a radio module under FCC rules, which in turn will significantly reduce the cost of conformance testing Raspberry Pi–based products.
