I want to use other GPIO pins but the DAC in question doesn't have any sort of breakout for the unused pins.
Does a breakout board exist that could be placed between the RPi and the DAC?
Other option is the remove the header on the DAC and solder in a new stacking header like this, but I fear I would ruin the DAC board
Thanks, that looks like it might be the best solution to stack under the DAC. A few right angled headers could be ideal for easy access.alphanumeric wrote:I used one of these, https://www.adafruit.com/products/2310 soldered to one of these, https://www.adafruit.com/products/1979 It's plugged into my A+ with a sense hat plugged on top of it. I used it to get some separation between my Pi and sense hat. I was having a heat transfer issue. I am going to be adding a RTC to the proto hat. The GPIO pins are all brought out and labeled for you. Just make sure you get the one "without" the eprom on it. Otherwise you won't be able to stack another hat on top of it.
I think that's route I'll go for. Even better that the Adafruit protoboard is available in the UK for less than a generic version on ebay.alphanumeric wrote:For me, under was better. I'm using the LED matrix on my sense hat to display a scrolling message with date, time, temp, etc info. I need it clearly visible. Plus, unsoldering the current header on the sense hat would have been a real pain. It's a two piece header that's soldered to both sides of the circuit board. I didn't have to unsolder anything, and only had to solder on the one stacking header. It was a plus, plus for me.
