Raspberry Pi 3 Model A

Raspberry Pi 3 Model A  is a less expensive and smaller version of Pi 3 B . Like the Raspberry Pi 3 Model B , it boasts a 64-bit quad core processor running at 1.4 GHz, dual-band 2.4 GHz and 5 GHz wireless LAN, and Bluetooth 4.2/BLE. The Raspberry Pi 3 Model A Plus has the same mechanical footprint as the Raspberry Pi 1 Model A . Specifications Processor: Broadcom BCM2837B0, Cortex-A53, 64-bit SoC @ 1.4 GHz Memory: 512MB LPDDR2 SDRAM Connectivity: 2.4 GHz and 5 GHz IEE 802.11.b/g/n/ac wireless LAN, Bluetooth 4.2/BLE Access: Extended 40-pin GPIO header Video & sound: 1 × full size HDMI, MIPI DSI display port, MIPI CSI camera port, 4 pole stereo output and composite video port Multimedia: H.264, MPEG-4 decode (1080p30); H.264 encode (1080p30); OpenGL ES 1.1, 2.0 graphics SD card support: Micro SD format for loading operating system and data storage Input power: 5 V/2.5 A DC via micro USB connector / 5 V DC via GPIO header Environment: Operating temperature, 0–50°C Production lifetime: The Raspberry Pi 3 Model A will remain in production until at least January 2023 The dual-band wireless LAN comes with modular compliance certification, allowing the board to be designed into end products with significantly reduced wireless LAN compliance testing, improving both cost and time to market.
