The Lowdown
The article delves into discovered device tree files in the Raspberry Pi Linux kernel, revealing clues about two unannounced boards: the Raspberry Pi Zero 3 W and the Raspberry Pi 4 Model A. This unofficial peek offers insights into potential hardware upgrades and strategic product decisions for the popular single-board computer line.
- Raspberry Pi Zero 3 W: Expected to be a successor to the five-year-old Zero 2 W, it reportedly features the Broadcom BCM2711 SoC, the same quad-core Cortex-A72 chip found in the Raspberry Pi 4. This upgrade would provide a significant performance leap, though thermal management in its tiny form factor is a potential concern. The device tree suggests features like a potential SPI flash bootloader, a single HDMI output, and possibly a physical power button, while eMMC support is speculated but unlikely to make it to the final, price-sensitive board.
- Raspberry Pi 4 Model A: This model resurrects the
