A focused e-paper platform for displays that stay useful.
PaperMono combines a high-resolution touch e-paper display, adjustable front light and an ESP32-S3 development platform in a slim handheld form. Choose Standard for integrated LoRa and NFC, or Lite for projects that only need the shared display platform.
Choose only the radio hardware you need.
Both versions share the same core display experience. Standard adds integrated LoRa and NFC hardware; Lite omits those two radios for a streamlined display platform.
