Hi,
The FAQ says the DAC+ is available with no connectors, so as to replace them by stacking headers. Where can I buy it ? Can't see no such product in the shop...
Thanks!

HiFiBerry team Dear Benoit,
looks like we forgot to update this. The DAC+ is not available without connectors. There is a second row where you can solder a male header that is connected in parallel to the original extension header.
Best regards

benoit.guchet I'm not sure I understand this, do you mean we cannot add proper stacking headers no more?
What is a "male header", can I find it in your shop?
Many thanks again! -
HiFiBerry team Dear Benoit,
we do not offer the option for stacking headers anymore. There were to many problems that people damaged the board during soldering.
A male header is a pinheader like this:

We don't offer them in our shop, but they are available at any electronic retailer.
You can solder them onto the board on the second row of pinholes. Note that there is no warranty when additional components have been soldered onto the board.
Best regards

benoit.guchet Ok I get it, thank you.
But as the second row is not at the same place as the first row, won't any 3rd card be displaced (not centered as it should be) ? -
HiFiBerry team Dear Benoit,
stacking multiple cards on the Raspberry Pi is not supported. As multiple cards might use the same pins, the Raspberry Pi foundation decided that Raspberry Pi HATs can't be stacked. E.g. the EEPROM on the card that identifies the card can be addresses only on a single board. The risk that multiple cards do not work together is quite high, therefore we don't support this.
Best regards

benoit.guchet But that's the goal of the second row isn't it ? -
benoit.guchet Or do you mean you don't guarantee any 3rd card to work with DAC+, and therefore you don't support it - support in a "professional" meaning ?
I'm planning to use DAC+ with Adafruit TFT 2,8" display; used GPIO seems not to be the same, so it should be ok with some tweaks.
Anyway thanks again for your quick answers. -
HiFiBerry team Dear Benoit,
we can't and won't guarantee that another board will work together with our cards. Even if the GPIOs are not used, there are several other things that can go wrong. One thing is power consumption, another one are drivers. Sometimes other boards need special kernels, that might not include our drivers. This is specifically true for the Adafruit display that does not work with the standard kernel.
The second pin row is made for people that want to connect simple things like an IR sensor or a simple character display.
Best regards

benoit.guchet Ok, I'll try anyway, thanks for all Daniel!
