The Raspberry Pi 4. [credit: Raspberry Pi ] The Raspberry Pi 4 is approaching its first birthday in a few months, but it's already getting an upgrade: more memory. The Raspberry Pi launched in June 2019 with 1GB of RAM for $35, 2GB of RAM for $45, and 4GB of RAM for $55, but today the Raspberry Pi Foundation announced that the 2GB model is getting a permanent price drop to $35. The rest of the specs are the same as always: a Broadcom BCM2711 SoC with four 1.5GHz Cortex A72 CPU cores, Gigabit Ethernet, two USB 3 ports, two USB 2 ports, a headphone/composite video jack, and two micro-HDMI ports capable of powering two 4K monitors. Interestingly, the foundation says the 1GB version of Pi 4 is sticking around and "will remain available to industrial and commercial customers, at a list price of $35." If you were using fleets of these things for some industry project before, you can still get the old version and not change anything.
