The Eink Feather Friend is much friendlier - it comes with 256 Kilobit (32 Kilobyte) SRAM chip. That means you can control up to a 4.2" 300x400 tri-color display (300*400 * 2 colors / 8 bits-per-byte = 30KB). This chip shares the SPI port the eInk display uses, so you only need one extra pin. And, no more frame-buffering! You can use the SRAM to set up whatever you want to display, then shuffle data from SRAM to eInk when you're ready.
