Jeff Geerling ☛ New 2GB Pi 5 has 33% smaller die, 30% idle power savings
Raspberry Pi launched the 2 gig Pi 5 for $50, and besides half the RAM and a lower price, it has a new stepping of the main BCM2712 chip.
[...]
For now, the biggest difference between the 2, 4, and 8 GB PI 5s for most people would still be having more RAM. If you know you can run your apps in 2 GB, this is a great little Pi for that. If you can't, then I think Raspberry Pi set up the 4 GB Pi 5 as the 'goldilocks': Not too expensive, with just enough RAM for most uses.

Hackaday ☛ Walking The Plank: Add-Ons For The Bus Pirate
The Bus Pirate multi-tool has held a place of honor in many a hardware hacker’s toolbox for years, and the latest generation of the gadget powered by the Raspberry Pi RP2040/RP2350 offers significantly enhanced capabilities over the original PIC versions. We took a look at the new Bus Pirate when it started shipping back in February, and while the firmware was still in the early stages back then, it was already clear that creator [Ian Lesnet] and his team had put together a compelling product.

Raspberry Pi ☛ What's new in Raspberry Pi Pico 2
There are two interesting things from the circuit perspective: one is that we’ve doubled the Flash memory, so you’ve got 4MB on Pico 2 vs 2MB on the original Pico. The other is to do with the way that power is supplied to the chip.
RP2040 has an onboard linear regulator that takes 3.3V and regulates it down to 1.1V for the processor core. RP2350 has a switch-mode power supply on board, which does the same thing, but is more efficient.

Using RISC-V cores on the Raspberry Pi Pico 2 board and RP2350 MCU - From blinking an LED to building Linux - CNX Software
Raspberry Pi Pico 2 was released last month with a Raspberry Pi RP2350 microcontroller equipped with two Arm Cortex-M33 cores and two 32-bit RISC-V “Hazard3” cores with up to two cores usable at any time. So in this guide, we’ll show how to use the RISC-V cores on the RP2350 MCU, compare their performance against the Arm Cortex-M33 cores, and even build Linux for RISC-V for RP2350 boards that have PSRAM.
Apart from the extra memory and more powerful cores, plus new features related to security and the HSTX interface, the Raspberry Pi Pico 2 and Pico will be very similar to the end user and the instructions in our article “Getting Started with Raspberry Pi Pico using MicroPython and C” remain valid. I don’t think there’s a MicroPython RISC-V image yet, so we’ll focus on running C programs on the RISC-V cores.
