  • Raspberry Pi 3B vs Raspberry Pi 3B + minicomputer comparison.
    Article from Micros


    Everyone has probably heard about the Raspberry Pi. The popularity of this miniature computer exceeded all expectations. This SBC platform is constantly evolving. Recently, RPi2 and RPi3 have been the subjects of frequent comparisons. We currently have two models of version three: RPi3B and RPi3B +. The new RPi3B + model will remain in production until at least 2023.


    CPU: the 3B + version has a clocked Broadcom BCM2837B0 chip 1.4GHz (Cortex-A53 ARMv8 64-bit SoC),
    version 3B is BCM2837 @ 1.2GHz (both GPU: Broadcom VideoCore IV). The SoC version 3B + has a partially metal housing for the integrated circuit.

    RAM: we have both 3B + and 3B versions 1GB RAM.

    WiFi: in the 3B + version we have WiFi 802.11.b / g / n / ac 2.4GHz and 5GHz ,
    in version 3B 2.4GHz .

    Bluetooth: In 3B + BLE 4.2 ,
    in 3B BLE 4.1 .

    LAN: in 3B + GBE (limited to 300Mbps via USB2.0) and power supply PoE via PoE HAT,
    in version 3B FastEthernet 100Mb / s.

    USB: in both cases 4x USB2.0.

    Interfaces: in both casesGPIO, CSI Camera Port, Touchpad Display DSI Port, Stereo Audio Out, and HDMI Out.

    The 3B + version, thanks to the increased SoC clock speed, provides the computing power increased by several percent.
    Increased computing power translates into higher power consumption in the 3B + model (if necessary, we can lower the SoC timing).
    In terms of communication, we get 3x greater LAN bandwidth and dual-band WiFi.
    By default, Rpi3B + is ready to boot from a micro SD card or USB stick.

    Which changes to RPi 3B + do you find useful, what functionalities should appear in the next versions of the Raspberry Pi?

    What possibilities should the successors of the 3B + model have, a SATA connector, better energy management, and maybe a connector for powering and charging a Li-ion battery?

    I find that the font looks bad when enlarged and bold at the beginning of the article.
    I miss a SATA connector. If not for this, I would have bought it.

    SBC platforms are growing fast, I think I even missed 3B +, but here the jump from the 3B version to the 3B + version of the Raspberry is mainly the development of WiFi + connectivity symbolically 3x faster Ethernet. SoC remained the same.

    In some applications, a SATA connector (preferably 2 ports) would be useful, in others more GPIO (preferably a specialized chip connected with an internal bus to the SoC. Another interesting option would be an on-board FPGA. (periodic wake-up, reaction to WOL, or other external event).

    Such a branching of the SBC model into models:
    - general application
    -high computing performance
    - support for SATA drives
    -a lot of GPIO
    -energy efficiency
    - special versions, e.g. made of FPGA
    would be an interesting thing, but 6 specialized models are harder to maintain than one general-purpose one ... especially since PiHats can be used.

    @Jawi_P is it the first sentence repeating the title? in fact, this sentence is already visible at the top of the post as the title.

    What would I add to my wish list? Modestly
    "Normal" DC power socket, and PRU microcontrollers as in BeagleBone, which solve many problems in applications where we need both Linux and realtime control: robots, control of cnc machines, lasers, ws28xx led strips etc.

    The manufacturer does not want to mount SATA
    Actually, some strange politics, but they have some purpose.
    Basically, with most cases it is not possible to mount even the smallest SATA drive.
    Besides, there would be a problem with its power supply, as that would mean another 1A plus.
    I would see 2 GB of Ram more

    The first Raspberry Pi was built on SoC for DVD or BR players. Some sort of Broadcom production waste.
    Such an arrangement, because the creator was an employee of Broadcom.

    And so it goes on in subsequent versions. The current chip is a tablet chip. Therefore, there is no Ethernet or SATA.

    There are dozens of better SoCs on the market (practically everything that is in Android boxes). Gigabit ethernet, SATA, 3GB RAM, fast flash etc etc, there are even similar formats to RPi.
    But the community around RPi is the largest and it is the most popular product.

    The Raspberry Pi Foundation (angola) also has a tragic approach to product development.

    As for SATA, here is the connection of the PIC controller to the SoC in the Tp-link router:

    unfortunately, the performance of the SoC significantly reduces the transmission speed.
    Perhaps this is one of the reasons for the lack of SATA, it is easier to give USB and when someone needs SATA, you can connect a USB to SATA converter.

    Sorry for digging up the topic, but in my opinion, USB 3.0 should be replaced by USB 3.0, then everything else for SATA would make sense to plug in USB 3.0.

    With USB3.0 it is a bigger competition, because everything on the RK3399 has this interface :) And I don't know if sometimes it is not H6 from allwinner (orangepi lite 2, orangepi 3)
