Who designed the MSP430F5529 Dev Board!

Part Number: MSP430F5529
Other Parts Discussed in Thread: MSP430F5525, , MSP430F5510, MSP430F5340

Tool/software:

Who designed the MSP430F5525 development board?

Of the plethora of I/O pins, they only brought out one full 8 bit port to the headers. And two of these bits share the serial TX & RX?

So I need a full 8 bit data port plus RS232 I/O?

P2 and P6 both have one missing bit so it looks like I have an 80pin LQFP hand soldering job to do !

Yes I know how to byte split, but that's extra clock cycles to deal with in a rather tight timing window!

What were they thinking? Just provide a few more header pins!

    Hi, 

    Sorry for the inconvenience.

    For the BoosterPack on the LaunchPad, we must select the pin following the standard of BoosterPack.

    The main standard reference is the peripheral function of the pin.

    Make sure BoosterPack connector have the maximum compatibility of the interface.

    This standard does not take into notice the need for a group of GPIOs.

    If you need more IO, please try to use the corresponding socket board.

    Not only TI. Other vendors are also for micro with 100 or more pins only few of them rooting, to be available for connection on PCB.

    Usually some members in DIY community forums make breakout boards with all pins available. There was open source MSP430F5529 project made in eagle on 43oh (not live anymore), but I think I have it somewhere. By design files JLCPCB (or some other PCB house) for few $ can made board than you can populate with parts.

    I made one for MSP430F5510, with all available pins...

    I realize the problem with multi purpose pins. But I think at least one full 8 bit port should be exposed that does not share other popular peripherals.

    But then perhaps they did do just that and considered RS232 is rather obsolete. I could go straight to PCB assuming this processor is a good design fit and it probably is as the current design is an MSP430F5340, the 5529 is better in every aspect. But that's a $5000 cost for just five boards with components installed.

    I managed to connect a kynar wire to an unrouted pin to get what I need.
