Hi,
Does the N-Drive Shield support 3.3V logic, if not do you have a 3.3V logic supported module? I have an Adafruit Grand Central which is 3.3V logic and I’m connecting five +12V lamps and one +5V NeoPixel strip. I’m not sure I can mix the 12V and 5V with this N-Drive. Does the VIN pin on the FET Drain Connectors needs to be connected to?
I tried connecting the NeoPixels to the Grand Central but with 500 pixels it causes slow down for other things in the app when the NeoPixel changes solid colour on MOSI (SPI) pin. I’m not running out of memory it seems the 12000 bytes cannot be allocated because there is not a big solid chunk of 12000 bytes in RAM.
Any help appreciated
