Raspberry Pi Pico 2: a RISC-V bet!
https://www.youtube.com/watch?v=oXF_lVwA8A4

The RP2350 is Raspberry Pi’s second-generation in-house microcontroller design. The Raspberry Pi RP2350 is a major upgrade over the earlier Raspberry Pi RP2040, boasting newer Arm Cortex-M33 cores running at a faster 150MHz, almost twice the static RAM (SRAM) plus support for external pseudo-static RAM (PSRAM), an additional programmable input/output (PIO) block, and more — but it also brings with it an architectural complexity: the presence of two RISC-V cores, based on the free and open source Hazard3 design, which can be chosen in place of the Arm cores or even split with one Arm and one RISC-V core running simultaneously.

New microcontroller boasts a choice of 150MHz Arm Cortex-M33 or RISC-V Hazard3 cores, a dedicated display peripheral, 520kB SRAM, and more. RP2350 is built using quad-core dual-architecture with two ARM and two RISC-V cores, but only two of those four cores can run at the same time. There is 520 Kb of SRAM memory on the chip and the new features include Arm TrustZone, 8 Kb OTP memory and Secure Boot support. The previous PR2040 had two Arm Cortex-M0+ cores with a maximum clock frequency of 133 MHz and 264 KB of SRAM memory. It is possible to integrate extra two megabytes of Flash to the same chip package.

“Raspberry Pi Pico 2 is our new $5 microcontroller board, built on RP2350: our new high-performance, secure microcontroller,” the company says of its latest launch. “With a higher core clock speed, double the on-chip SRAM, double the on-board flash memory, more powerful Arm cores, optional RISC-V cores, new security features, and upgraded interfacing capabilities, Raspberry Pi Pico 2 delivers a significant performance and feature boost, while retaining hardware and software compatibility with earlier members of the Raspberry Pi Pico series.”

For programming Raspberry Pi RP2350′shave Day-One Rust Support. Pallant says, “this is the first ever microcontroller launch with Rust support out-of-the-box.” Raspberry Pi Pico 2 board serves as a quick-start development platform.

Raspberry Pi 5 is a higher-performance computer than Raspberry Pi 4. It promises to offer 2–3× the speed of the previous generation. The new board features silicon designed in‑house for the best possible performance. Raspberry Pi features a new quad core 2.4 GHz Cortex-A76 Arm CPU (in BCM2712 SoC), a new Southbridge that promises to improve USB 3 throughput and a new VideoCore VII GPU.

Key features include:

• 2.4GHz quad-core 64-bit Arm Cortex-A76 CPU
• VideoCore VII GPU, supporting OpenGL ES 3.1, Vulkan 1.2
• Dual 4Kp60 HDMI® display output
• 4Kp60 HEVC decoder
• Dual-band 802.11ac Wi-Fi®
• Bluetooth 5.0 / Bluetooth Low Energy (BLE)
• High-speed microSD card interface with SDR104 mode support
• 2 × USB 3.0 ports, supporting simultaneous 5Gbps operation
• 2 × USB 2.0 ports
• Gigabit Ethernet, with PoE+ support (requires separate PoE+ HAT, coming soon)
• 2 × 4-lane MIPI camera/display transceivers
• PCIe 2.0 x1 interface for fast peripherals
• Raspberry Pi standard 40-pin GPIO header
• Real-time clock
• Power button

The Raspberry Pi 5 claims to have two to three times the processing power of the Raspberry Pi 4, already a powerful single board computer. Available in 4 and 8GB RAM capacities (with 1 and 2GB models to come later), the Raspberry Pi 5 is the same basic size and shape as the Model 4 B, but adds a number of long-requested features such as a built-in real-time clock, a PCIe 2.0 connector and a power button.

There’s a slew of little improvements throughout the board, including a built-in fan header with mounting holes, faster and dual camera connectors and a microSD card reader that works with higher-speed cards. The device has dual HDMI ports, with each one having a 4K display output at frame rates of up to 60 fps, as well as support for HDR.

While the main system on a chip is still designed by Broadcom, the Raspberry Pi 5 is the first full-size Raspberry Pi that uses custom silicon — the RP1. This is a southbridge chip, meaning that it handles I/O functions and replaces some the functions that were previously handled by the main system on a chip. It also replaces most of the analog components of the main SoC: GPIO and associated low-speed peripherals, Ethernet MAC, MIPI CSI/DSI, analog TV.

Raspberry Pi 5 is coming coming in October 2023. At just $60 or $90 MSRP, the 4 and 8GB models are a mere $5 more than the same memory capacity SKUs of the Raspberry Pi 4. Upton said 100,000 units should be available at launch – scheduled by the end of October. The Raspberry Pi 5 will remain in production until 2035.

You will need the latest version of Raspberry Pi OS, Bookworm, for your Raspberry Pi 5. Bookworm will launch in mid-October.

Raspberry Pi 5 won’t fit the Raspberry Pi 4 Case. Raspberry Pi 5 is faster and more powerful than prior-generation Raspberry Pis, and like most general-purpose computers, it will perform best with active cooling in a Pi 5 case designed specifically for it. For powering this new computer, a high-quality 5V 5A USB-C power supply is needed (such as the new Raspberry Pi 27W USB-C Power Supply).

However, there is some bad news to stir into the pot. The audio and composite jack has been ditched. According to Pi supremo, Eben Upton, this was due to space constraints on the board. As for what users requiring composite functionality should do, Upton told us: “For composite video, you can see there is a pair of 0.1″ pads on the bottom edge.” “There’s isn’t a recommended solution for audio, other than to use either a USB audio device or HAT.”

Pico provides a single push button, which can be used to enter USB mass-storage mode at boot time and also as a general input, and a single LED. It exposes 26 of the 30 GPIO pins on RP2040, including three of the four analogue inputs, to 0.1”-pitch pads; you can solder headers to these pads or take advantage of their castellated edges to solder Pico directly to a carrier board.

It is programmable with Python and C/C++. Cross-platform toolchain for development on Windows, macOS, and Linux — including, naturally, the Raspberry Pi family itself Supports TensorFlow Lite.

Raspberry Pi is looking to do for the microcontroller market what they’ve already done for single-board computers with the launch of the Pico. The board — priced at just $4 — is based on the RP2040, a dual-core Cortex-M0+ processor designed in house. It designed to be easy to taken into use.
