RT5350F board update


We got heap of good tips and suggestions about RT5350F some posted on the blog more by e-mails. Thanks guys!

What we also saw is that all these devices on the market are just PCBs and missing something important to complete project – plastic enclosure.

So as next step after finishing RT5350F-OLinuXino prototypes and test them will be to try to fit it inside the DB25 plastic shell like PIC-MICRO-WEB:


With just one Ethernet connector and GPIOs and power supply on the 25 pin connector.

And another version with WIFI with external SMA connector on the place of the Ethernet connector, so antenna like this one could be connected:



This way RT5350F-OLinuXino will become much more useful and easy to PLUG-AND-PLAY with simple DB25 connector to other boards

On the DB25 connector there will be UARTs, I2C, I2S, SPI, GPIOs. If we find space we may add I2C ADC as well.

Still is not clear if this will be good solution as we may not have enough space or the RT5350 may not cool well inside plastic box, we will see after we complete first prototypes.

    Oh yeah, what a damn great idea! ❤

    I’d like a small implementation with WIFI, ethernet and USB 2.0 : for wireless audio application, using USB sound input(or output) interface.
    For other use : a connector for flat cable to provide access to all ethernet interfaces.
    I wonder if DB25 is not a too old box/interface…

    Why not to consider OEM usage too? I.e. to design that board is such a way that it will be easy mountable on another board:
    – don’t put chips on bottom in order to solder that board easily on top of another board
    – take in mind dimensions of some metal shields that can cover that board (w/o build in PCB antenna of course)

    Few hints for the devkit board:
    – put FT232 or similar chip connected directly to the serial line – this helps a lot
    – add real PoE (802.3af or 802.3at)
    – add relay outputs / optocoupler isolated inputs
    – bundle with aluminium or durable plastic box that can be used for harsh environments

    The hints from Atanas Palavrov are my wishes too. +1

    I would personally prefer very much an EVB board with 2x ETHERNET ports, USB and antenna connector. Much more useful. This is too limited and looks like something from the previous millenium 🙂

    There are slightly bigger cases i think they are meant for ribbon cables, hopefully this would allow for antenna and rj45…
    Also you could use a 44pin hd-sub connector instead of an ordinary 25pin to add a couple of ethernet ports.

    When i first heard about it i was thinking it would look like TP-Link TL-WR703N

    DB25 version definitely requires USB A and probably two ethernet ports (smd jacks top and bottom but double jack on one side should also fit). Plus microUSB for power.
    have no idea how you would fit all this, but at least give it a try 🙂
    and DB25 RS232 compatible pinout, with pins 1-8, 20, 22 for serial port or at least 1,2,3 for GND, TX, RX

    Does this chip supports USB? or USB-OTG?

    Any chance to have this module breadboard compatible?

    Why on earth would you not make this compatible with PoE injectors as an alternative to powering it via the DB25 jack? Please, I don’t want to have more cables than absolutely necessary!
