It will be preferred to use non-function tied pins for GPIO usage.
D0 and D1 used by the relay shield coincides with the I2C pins which becomes and issue if the user wants to use them to hook other peripherals.
I2C pins are not available where they are needed for Arduino Shields, and new Arduinos have an extended pin set also not supported by the current Shield Shield. There's probably a lot that can be done here for a more usable v2.0 Shield Shield.
Currently
Arduino Spark Core Shield Shield
A4 (SDA) D0 (SDA) D3
A5 (SCL) D1 (SCL) D5
* Arduino Leonardo also has dedicated SDA, SCL pins now

The docs don't tell anything about the color codes of the charge status LED. This could be fixed, but it might even be possible to add such info on the bottom silk screen.

Blue while charging and then turning RED can get people worried (did me ;-) )

presently the copper traces are only on the bottom layer. we should use of the top layer as well, just to make sure it has enough copper to handle the current
Would be really awesome to have 0.1" spacing through-holes for attaching your own status LEDs for each relay. Makes it easier to mount the whole thing inside a box but still know what's going on. Let them add their own resistors based on LED brightness and color.
some thing like this: http://www.digikey.com/product-detail/en/504102B00000G/HS104-1-ND/5832
Suggesting to have the .sch and .brd files in PDF format for super easy reference without EagleCad.
i can do that but just opening an issue here in case i forget to do so
it would be good for the schematic to have the Rev number and designer info etc.
I think it is missing for the:
While it is possible to get the info from the docs a silk screen would have helped anser this question

Can you be more descriptive in the readme about which parts of the xml represent the (2?) different driver types and which one to comment out? Kind of left me high and dry at that part.
I cannot edit it. At all. I even unlocked the root user and it still won't let me edit the file. I cannot find a single way to do this.
We should have a tiny grove at the bottom of the Photon area to stick our finger in and attempt to wiggle the photon out...
Relay shield transistors are triggered by 5V input, not 3.3V. Need to re-spec the transistors for 3.3V input.
The Link is still broken. It leads to github's 404. plz fix.
I want to download the openocd config file which the readme links to the word 'here' in the second paragraph, but the link is broken. It leads to github's 404 plz fix.
Hi,
i recently found your wiki entry https://github.com/spark/shields/wiki/Viewing-threads-in-openocd
I was hoping to get OpenOCD with FreeRTOS Thread Awareness working but no success.
the recent versions of OpenOCD do not provide *.cpu files as stated in your wiki.
I'm trying to start openOCD the following way, but it fails:
openocd -f board/stm32429i_eval_stlink.cfg -c "-rtos auto"
invalid command name "-rtos"
any hints on this problem?
Why?
We are going to hand solder these and the cream would add unnecessary solder paste
I checked up the design of the Power shield schematics of v210 and:
Jumper pad of I2 makes it hard for a user to alternative between 100mA/500mA setting since the ISET2 pins need to be grounded to enable a 100mA. i.e. The jumper pad doesn't really serve a purpose here.
We should use a 3 way jumper, one side to Ground and one side to +5V
Right now, it's too close to the 100uF capacitors, which forces it to twist in order to fit onto the board. See attached pic. We just need to give it maybe 10mm of clearance.
we are under utilizing the core I/Os here by using only 4 of the 16 available channels. we could have a secondary shield that is daisy chained to add more relays.
