Raspberry Pi LtdRASPBERRY PI 3 A+嵌入式系统开发板和套件

The Raspberry Pi 3 A+ is a single-board computer in a smaller form factor than the Raspberry Pi 3. The Raspberry Pi 3 A+ is powered by a Broadcom BCM2837B0 SoC, which integrates a 64-bit quad-core ARM Cortex-A53 operating at 1.2 GHz, and the system also integrates 512 MB of LPDDR2 SDRAM. The SoC also integrates a GPU allowing the Raspberry Pi 3B+ to operate at 1080p at 30 fps while also integrating H.264 and MPEG-4 decoding, and the use of an HDMI connector allows for connecting to HDMI-compliant screens.

Wireless network connectivity is provided on the Raspberry Pi 3 A+ via Bluetooth, 2.4-GHz Wi-Fi, and 5-GHz Wi-Fi. However, unlike other Raspberry Pi systems, the Raspberry Pi 3 A+ does not include a wired Ethernet connection. The removal of this connection method helps to reduce the overall weight and size of the system, thereby making it applicable to applications with strict size and weight constraints.

I/O connectivity on the Raspberry Pi 3 A+ is provided via a USB2.0 port, a CSI camera port, a DSI display port, a four-pole stereo and composite video output, a micro SD port for use with operating and file systems, and a 5-VDC power input. Further I/O support is provided with the use of a 40-pin GPIO header that allows access to various ports on the Broadcom SoC, including I2C, SPI, and UART.
