They have gigantic electronic paper 'static' displays - that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!\u003c\/p\u003e\n\u003cp\u003eWe've liked these displays for a long time, and we've got Arduino\/CircuitPython drivers for tons of the various display chipsets, so wouldn't an e-paper RP2040 Feather make a ton of sense? Luckily for us, just about every small-medium size EInk display made these days has a standard 24-pin connection. This Feather will add all the power supply support circuitry and level shifting so you can attach your favorite display - we've tested it with up to 5.6\" sized 7-color ACeP displays.\u003c\/p\u003e\n\u003cp\u003eSince all ePaper displays with the 24-pin interface require you to buffer the layers of data and write them all out at once over SPI, the RP2040 chip is an excellent driver. It has 264K of internal SRAM so even with the largest displays, there's plenty of memory to store all the image data plus run your own code. We also put the display on it's own SPI port so that the Feather's main SPI port can be used for other peripheral devices.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes not come with an EInk display or extension cable!\u003c\/strong\u003e For use with just about any EInk display with a 24-pin FPC connector. \u003ca href=\"https:\/\/learn.adafruit.com\/assets\/57645\"\u003eSee these schematics to verify that your display matches before purchasing\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eFeather is the development board specification from Adafruit, and like its namesake, it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores. \u003ca href=\"\/collections\/feather\" target=\"_blank\"\u003eWe have other boards in the Feather family, check'em out here\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eAt the Feather's heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the \u003ca href=\"\/products\/raspberry-pi-pico\" target=\"_blank\"\u003eRaspberry Pi Pico\u003c\/a\u003e. This chip has a whopping MB of onboard QSPI FLASH and 264K of RAM!  There's even room left over for a STEMMA QT connector for plug-and-play of I2C devices.\u003c\/p\u003e\n\u003cp\u003eTo make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built-in battery charging. You don't need a battery, it will run just fine straight from the USB Type C connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when it's available. While the RP2040 is not designed for low power usage - you can get down to about 1.5mA of power draw in sleep mode.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHere're some handy specs!
