Raspberry Pi 3 Model A+ (Single-Board Computer/Broadcom BCM2837B0/Quad-Core Cortex-A53 1.4GHz/512MB LPDDR2/Compact No-Ethernet Pi 3) Review
The raspberry pi 3 model a+ price and size questions usually come from people needing the smallest, cheapest Pi footprint with WiFi.
It drops Ethernet and 3 of the 4 USB ports versus the Model B+ to shrink the board and the price, which is the right trade only if your project runs on WiFi and doesn't need multiple USB peripherals.
The Trade-Off That Defines This Board
One USB port and no Ethernet jack means this is a WiFi-only, mostly-single-peripheral board. It fits battery-powered projects, compact camera rigs, and embedded builds where board footprint matters more than expandability.
