Raspberry Pi 4 Model B (4gb RAM)

Description

•  Raspberry Pi 4 Model B (4gb RAM) key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K
• Due to the higher power requirements, the Raspberry Pi 4 requires a 3.0A USB-C power supply (sold separately).
• If you have an existing power supply that is rated at 3.0A, you may utilize a microUSB to USB-C adapter to utilize your existing MicroUSB power supply to power the Raspberry Pi 4.
• The dual-band wireless LAN and Bluetooth have modular compliance certification, allowing the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market.
