1.69 Inch ePaper Display Overview
The ND017EPN400400-B01 is a 1.69-inch six-color round E Ink ePaper display with 400 × 400 resolution, an IST7601CA0 controller and a 32-pin FPC. Its reflective circular viewing area supports compact visual indicators and illustrated information. Hardware integration should account for the connector assignments, SPI signaling, drive voltages, power sequencing and waveform requirements before prototype wiring is finalized.
Smart-home status indicators, electronic badges and equipment labels can combine symbols and short text within the round image area. For ESP32 or STM32 nodes and Raspberry Pi evaluation hosts, NoseDisplay can assess driver circuitry and firmware adaptation. OEM reviews may include circular cover-lens alignment, enclosure clearances and FPC routing, with refresh behavior and battery-system power budgets verified for each configuration.
The ND017EPN400400-B01 is a 1.69-inch six-color round E Ink ePaper display with 400 × 400 resolution, IST7601CA0 control and a 32-pin SPI FPC. Its reflective viewing area suits illustrated badges, home-status indicators and compact equipment labels. ESP32, STM32 or Raspberry Pi designs require matched driver circuitry, initialization and verified waveforms. NoseDisplay can review circular cover-lens alignment, FPC routing and enclosure clearances during OEM evaluation.

Matching Driver Board
NoseDisplay can review a driver solution for the ND017EPN400400-B01 using its IST7601CA0 controller, SPI interface and 32-pin FPC. The connector mapping and booster connections must be checked against this model rather than a different round module. ESP32, STM32 or Raspberry Pi hosts require suitable drive circuitry, initialization, image formatting and six-color waveform handling. Refresh current and standby system load need evaluation before estimating battery life; board compatibility and package contents remain project-specific.



Customization Options
OEM evaluation for the ND017EPN400400-B01 can cover its 32-pin FPC routing, IST7601CA0 driver circuitry, circular cover-lens alignment and compact badge or indicator enclosures.
