Is it possible to use 2.9″ ESPaper board to drive 7" epaper display ?

Question

Hello Experts,

I would like to drive a bigger epaper display with ESPaper board, is it possible to do that?

for example https://www.waveshare.com/7.5inch-e-Paper.htm , wanted to get some breaking news feed as well.

Kindly help me if there is a possibility or any starting point to do the same.

Thanks

Hi Brijesh

The passive components are not quite the same. If you look at the breakout board which comes with the 7.5" display then you'll see that there is a switch for 2.9" to "other" displays. It might work temporarily but I wouldn't recommend it permanently. You might damage the display

Kind regards,
