Makerfabs has launched a new 7.5-inch E Ink development board capable of rendering black, white, red, and yellow colors. The device is built around an ESP32-S3R8 controller and is designed for applications like voice-controlled interfaces and low-power dashboards.
Why it matters
The board offers a versatile hardware platform for developers seeking to create energy-efficient information displays. Its inclusion of both voice and motion-sensing subsystems expands the range of interactive projects designers can build.
The board features an ESP32-S3R8 with dual-core Xtensa LX7 processors, 8MB of PSRAM, and 16MB of SPI flash. It also includes a four-microphone array, a QMI8658A six-axis IMU, and wireless connectivity via 2.4GHz Wi-Fi and Bluetooth 5 LE.
The players
Makerfabs
Makerfabs is a hardware manufacturer that produces development boards and electronics components for engineers and hobbyists.
The details
Engineered for flexibility, the board manages components via SPI and USB interfaces while utilizing a JD79665 controller for image rendering. Developers can further customize the setup with an optional 3-megapixel OV3660 camera module.
Timeline
The product was released on October 1, 2026.
The Tech Race
This development board follows the industry trend of integrating ESP32-S3 microcontrollers into niche display applications to optimize low-power processing. It competes in an expanding sector where manufacturers are replacing static signage with smart, connected, and color-capable E Ink systems.
The base model is available for $59.80, with an optional camera module priced at $4.80 for developers looking to expand vision capabilities. The device operates within a temperature range of 0C to 40C, making it suitable for most indoor environment dashboards.
The takeaway
This development board highlights how multi-color electrophoretic displays are becoming increasingly accessible for custom low-power projects. Developers should note the 20-second refresh time when planning applications that require frequent screen updates.
