Hello,
without revealing any secret, is it possible to know the input voltage range of those boards, at least for the non-gadgeteer ones ?
I ask this because I’m currently creating a new shield that will need higher voltage than 9V. So I was wondering if I would be able to power the new boards with something like 12V or 15V from my shied or if I should envisage a reductor on it ?
Right now, only the good old Domino can support 12Vcc input but this board seems to become less popular
Why create a shield? Why not create a module instead? …smaller, cheaper, easier, more usable, no pin-overlap-problems…and you get to pick any power module you like.
The shield I’m creating is a new variant of my PandaMotors shield. It was meant to be used with Panda 1 which has been obsoleted.
Also, with the inclusion of the FEZ connect shield, many pins I’ve used in my shield are already taken by the SPI
Now, there are three main reasons for me to choose to create a shield instead of a module :
Usage :
the whole thing (FEZ board+Connect shield + my shield) will have to be as compact as possible and has to be “autonomous”, that is : it will be powered by a car battery in fields. That’s why I would like only one power plug on the device. A shield will be able to power the underlying FEZ board via the Vin pin.
Practicality :
[ulist]With PandaII/Domino (or Mini) there won’t be much wires flying around, apart from those needed for connecting external devices (temperature sensors, motors and switches).
With Gadgeteer, I will have to connect many IDC cables to my module, while at the same time wasting pins on some of them (unless I create my own module to avoid that, of course)[/ulist]
Final cost :
[ulist]Panda II or even Domino (if it comes back in stock) +
FEZ Connect shield +
My shield[/ulist]
will always be cheaper than :
[ulist]Hydra +
Client DP module +
Ethernet ENC28 Module +
My shield[/ulist]
I don’t really need the extra-power available on Gadgeteer boards, hence my choice of “original” FEZ boards.
Anyway, I will wait till the official announcement of the boards before creating the PCB. In the meantime, I will work on the schematics. That’s why I still need to know if I should add some components to provide lower voltage to the FEZ board.
Valuable feedback. Thanks.
I hope the new coming boards will cover your needs.
Don’t get me wrong, Gus : existing boards already fully cover my needs
The only thing is that I wouldn’t have to create yet another shield in the (short) future only because of some powering problem on the new boards. Or if Domino follows the same road as Panda 1 :snooty:
Well, I will add some regulator to get something around 9V for powering the underlying FEZ board. Am I ok in assuming that 9V will be ok on the new boards ?
