Raspberry Pi Zero 3W and Pi 4 Model A spotted in device trees

Linux device-tree files point to two unannounced Raspberry Pi boards: a Zero 3 W and a Pi 4 Model A. Both appear to use the BCM2711, the quad-core Cortex-A72 processor found in the Pi 4, suggesting a substantial performance increase for the Zero 2 W’s successor. The Zero 3 W’s configuration indicates one HDMI output, Wi-Fi and Bluetooth, the familiar 40-pin GPIO header, an SPI-flash bootloader and a possible power button. An 8-bit storage bus raises the possibility of eMMC, but microSD is considered more likely. PCIe and four-lane camera connections also appear in the files, though shared, potentially copied device-tree details make those clues uncertain.

The Pi 4 Model A follows the usual lower-cost Model A approach: it appears to omit Ethernet, a second HDMI output and analogue audio/composite video, while retaining microSD storage and adding power and activity LEDs, a bootloader and a possible power button. Its most notable potential feature is external antenna support, which could improve wireless reception inside metal enclosures. USB details are absent, so it is unclear whether the board will offer USB 3 or how many ports it will have. Neither device tree reveals RAM, clock speeds, prices, connectors or launch timing. The boards could extend the Pi 4 platform with a less expensive option and deliver a long-awaited Zero upgrade, but their specifications and affordability remain unconfirmed until Raspberry Pi announces them.
