The display offers red, yellow, black and white colours with a 416x250 resolution across the 3.7" panel, along with 170° viewing angles. It's the same panel as used in the 3.7" ePaper HAT (G) for Raspberry Pi, which may be a better option if you'd prefer the driver built in to a HAT.
Refresh time is around 20 seconds for a full refresh, and 12 seconds for a 'fast refresh'. As with all ePaper displays, it uses very little power - <0.01uA (almost nothing) when in standby, and around <30mW when refreshing.
Take a look at our ePaper section for many more options with different colours and sizes.
Driver board required but not included.
