Evaluation Tools / NHD-4.3CTP-SHIELD-N
« on: May 03, 2017, 11:16:12 AM »
Just starting a project with this shield. I'd prefer to use the Arduino MEGA

Can I ask a few beginner questions?

In the User Guide, the shield is shown plugged into an UNO and also shown plugged into a MEGA.
Assuming the MEGA is not a clone, is it safe to assume no solder jumpers need to be altered for my project to utilize the MEGA?

Any thoughts on getting access to pins (on the MEGA) that are not used by the Newhaven Display?
Would a PCB, pin breakout shield, sandwiched in between the Newhaven Display and the Arduino work?

On the MEGA, are these the only MEGA pins utilized by the Newhaven Display: D4, D8, D9, D10, SPI MISO, SPI SCK, SPI MOSI, 5V and GND?

There is a recommendation in the User Guide to use a 7V to 8V power supply, yet the MEGA allowable input is 7-12V?
Reason for the question is 12V power supplies are widely available.

How much current (from the 5V, MEGA regulator) will be available for my project?
I see the Newhaven shield uses about 400 mA MAX.

Thanks!
