SRAM or SDRAM

a2retro · July 23, 2018, 8:21pm

The web site (and some review sites) have conflicting information about the 8MB RAM. Some say SRAM and the Arduino web pages says SDRAM in the description and SRAM in the tech specs?

If I was a betting man I would guess it is most likely SDRAM.

I guess it's just me talking to myself

you're right, it's a SDRAM. at the moment that is used mostly by internal peripherals such as camera capture, frame buffer for HDMI, pixel buffer for NEOPIXEL etc. we are working to expose that also as general purpose RAM for other uses. suggestions are more than welcome.
