Modos Flow is a paper-like, 13.3-inch USB Type-C touchscreen monochrome or color monitor that builds upon the Modos Paper devkit introduced last year with an AMD/Xilinx Spartan-6 LX16 FPGA and STMicro STM32H750 Arm Cortex-M7 microcontroller. The main difference is that the Modos Flow is more like a consumer product with a full enclosure, a touchscreen, and optional stylus support, 4096-color e-paper display, and frontlight. Modos Flow specifications: FPGA – AMD Xilinx Spartan-6 LX16 FPGA running Caster gateware like the earlier devkit MCU – STMicro STM32H750 Arm Cortex-M7 microcontroller for USB communication, firmware upgrades, and standalone applications. Display 13.3-inch e-paper display with 3200 x 2400 resolution Refresh rate – 60 Hz with additional power, 40 Hz via a single USB-C cable Monochrome or 4096 colors/16 levels of grayscale Touchscreen support Optimized display modes for reading, browsing, watching, and writing Amber-tinted frontlight (color model only) Video Input – USB Type-C DisplayPort Alt-Mode with [...]
