Raspberry Pi is taking an unconventional approach to combat escalating memory prices and supply chain constraints. The company has quietly released the Raspberry Pi 4 Model B v1.5, a redesigned version of its popular single-board computer that can accommodate two LPDDR4 memory chips instead of one. The change gives Raspberry Pi manufacturing flexibility to use pairs of smaller, potentially cheaper RAM chips when single higher-capacity modules become too expensive or difficult to source.
The revised board, identifiable by a 2025 copyright date on the silkscreen and the revision designation "Rev 1.5" in system information, features a second memory chip location on the underside along with additional passive components. From a software perspective, the dual-chip configuration is transparent to users, though the board requires bootloader version pieeprom-2026-01-09.bin or newer to function properly.
This hardware revision comes amid significant price increases across the Raspberry Pi lineup. The company recently raised prices on 2GB through 16GB models, with increases ranging from $10 (€9) for 2GB variants up to $60 (€55) for 16GB boards. The 1GB models remain at their current prices. Full technical details are available in Product Change Notice 45 on the Raspberry Pi documentation portal.
