1.54inch E-Paper Display Development Board

The product is a high-performance, highly integrated microcontroller development board designed by Waveshare. It integrates high-capacity Flash and onboard 1.54inch e-paper display, features ultra-low power consumption and ambient light readability, suitable for portable devices and long-Batt-life scenarios. Integrated with an RTC chip, SHTC3 temperature and humidity sensor, TF card slot, low-power audio codec chip circuit, and Lithium Batt recharge and discharge management circuit. Reserved interfaces including USB, UART, I2C, and GPIO for easy functionality expansion and sensor connectivity, providing a flexible and reliable development platform for IoT terminals, electronic tags, portable displays, and other applications. RP2350A microcontroller chip designed by Raspberry Pi in the United Kingdom Adopts unique dual-core and dual-architecture design: dual ARM Cortex-M33 or dual Hazard3 RISC-V processors support, flexible clock running up to 150 MHz Built-in 520KB Static RAM, with onboard 16MB Flash Type-C port for easier use Onboard 1.54inch e-paper display, 200 × 200 resolution, features high contrast and wide viewing angle USB 1.1 with device and host support Low-power sleep and dormant modes Drag-and-drop programming using mass storage over USB Adapting 7 × GPIO pins and USB+/- pins 1 × I2C, 1 × UART, 2 × 12-bit ADC, 6 × controllable PWM channels Accurate clock and timer on-chip Built-in temperature sensor for real-time monitoring of chip temperature 12 × programmable I/O (PIO) state machines for custom peripheral support Specifications display panel | e-paper displayDisplay size | 1.54inch resolution | 200 × 200grey scale | 2 Communication interface | SPIfull refresh time | 2s display color | black, whitepartial refresh time | 0.3s Viewing Angle | >170°Display Type | Passively reflectiveOnboard audio codec chip Supports high-quality audio processing, providing clear and high-quality audio input and output Advantages of EINK E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper. E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect.
