Raspberry Pi has quietly launched a fresh variant of the Raspberry Pi 4 Model B. This release comes just days after an increase in prices for the Raspberry Pi 5, which is currently priced at $137 on Amazon. The new variant brings only minor technical adjustments to the existing single-board computer (SBC) lineup.

New Dual RAM Configuration

The latest addition is known as the Raspberry Pi 4 Dual RAM variant, officially named the Raspberry Pi 4 Model B Rev 1.5. This new model primarily features a dual-RAM setup. In a recent Product Information Portal (PCN) document, Raspberry Pi has also noted that this Dual RAM version benefits from better manufacturing processes through a method called intrusive reflow soldering.

Supply Chain Response

Furthermore, the company mentions that these changes are in response to ongoing uncertainties in the supply chain and pressures on component prices. For users, the Rev 1.5 board merely adds an extra RAM chip located on its bottom side. This new variant is still fully compatible with all current accessories and software platforms. However, Raspberry Pi does indicate that users must install bootloader versions released on or after January 9, 2026. For additional information, refer to the company’s PDF document.
