Welcome to the New Raspberry Pi 5 - Is it what you hoped?

We were told that there would be no Raspberry Pi 5 in 2023.

In fact it was said in a lot of places that was the case.

It turns out, that was a lie :D

 Raspberry Pi 5 8GB 

And what a delicious one it is.

• 2.4GHz quad-core, 64-bit Arm Cortex-A76 CPU, with 512KB L2 caches and a 2MB shared L3 cache
• VideoCore VII GPU
• LPDDR4X-4267 SDRAM (4GB and 8GB SKUs available at launch)
• 2.4 GHz and 5.0 GHz 802.11ac Wi-Fi
• Bluetooth 5.0 / Bluetooth Low Energy (BLE)
• Micro SD card slot, with support for high-speed SDR104 mode
• 2 × USB 3.0 ports, supporting simultaneous 5Gbps operation
• 2 × USB 2.0 ports
• Gigabit Ethernet, with PoE+ support (requires PoE+ HAT)
• 2 × 4 lane MIPI camera/display transceivers
• PCIe 2.0 x1 interface for fast peripherals
• 5V/5A DC power (PD enabled)
• Raspberry Pi standard 40-pin header
• Real-Time Clock (RTC), powered from external battery
• On-board power button!!

I cannot wait to get a hold of one, and I'm amazed that finally, we have need for a heatsink and fan, which comes with thermal pads!

Have you been waiting for a new Raspberry Pi? Perhaps you were content with the existing one? I'll be interested in putting it through its paces.

We previously asked you:  What would you look forward to being on the Raspberry Pi 5 ? - how does this meet up with your expectations?

    It looks like a nice incremental upgrade. I think the power switch is the standout new feature! A shame there nothing real-time such as an onboard RP2040.

    Oooh. It seems that there is an accessible PIO - and an unused M3. Awesome!

    I'll copy that here since it appears to be restricted on some accounts

    image

    And because frankly, using images of text is awful for finding information, here's what it says:

    "There is one PIO instance (4 state machines). It's identical to the PIO blocks on RP2040, except the FIFO depth is doubled. It has single-cycle bus access from the dual Cortex-M3 management processors on RP1, and the PIO FIFOs can also be accessed from the host processor (2712) over PCIe, but the PIO configuration registers are only accessible to the RP1 processors.

    One of the RP1's Cortex-M3's is currently going spare, so it should be possible to write your own Cortex-M firmware and load it into the 16kB per-Cortex-M3 private SRAM. There won't be any software support for this at launch though."

    Luke Wren is an engineer at Raspberry Pi. https://twitter.com/wren6991 

    That's brilliant.

    I think the UART port is there because the gpio header runs to the new chip vs the Broadcom soc (I guess it could have been mixed through too). Wonder what the new features are on the gpio pins :D

    edit: for a linux console over serial

    Did RPI design their own image signal processor in the RP1? So many questions!
