Product Features
This product is a high-performance, highly integrated microcontroller development board independently designed by Waveshare. It integrates a large-capacity Flash memory, an onboard 1.54-inch e-ink screen with extremely low power consumption and ambient light visibility, making it suitable for portable devices and long-battery-life scenarios. It integrates an RTC real-time clock, an SHTC3 temperature and humidity sensor, a Micro SD card slot, a low-power audio codec chip, and lithium battery charge/discharge management circuitry. It provides reserved expansion interfaces such as USB, UART, I2C, and GPIO for easy function expansion and sensor connectivity, offering a flexible and reliable development platform for applications such as IoT terminals, electronic tags, and portable displays.
- It uses the RP2350A microcontroller chip developed for Raspberry Pi.
- Its unique dual-core, dual-architecture design features a dual-core ARM Cortex-M33 processor and a dual-core Hazard3 RISC-V processor, with a clock speed of up to 150MHz, allowing users to flexibly switch between the two architectures.
- It has 520KB of built-in SRAM and 16MB of on-chip Flash memory.
- Adopting a Type-C interface, it keeps up with the times and eliminates the need to worry about whether it should be plugged in or out.
- It features an onboard 1.54-inch e-ink screen with a resolution of 200 × 200, boasting high contrast and wide viewing angles.
- Supports USB 1.1 hosts and devices.
- Supports low-power sleep and hibernation modes
- It can be recognized as a mass storage device via USB for drag-and-drop downloading.
- The RP2350A has 7 GPIO pins, with the USB +/- pins brought out.
- One I2C port, one UART port, two 12-bit ADCs, and six controllable PWM channels.
- Precise on-chip clocks and timers
- Built-in temperature sensor can monitor chip temperature in real time.
- 12 programmable I/O (PIO) state machines for custom peripheral support

Onboard audio codec chip
It supports high-quality audio processing, providing clear and excellent 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.
Application scenarios
Desktop temperature and humidity clock, e-reader, etc.
Dual-core, dual-architecture processor
Onboard dual-core ARM Cortex-M33 + dual-core Hazard3 RISC-V processor, operating at frequencies up to 150 MHz.
Supports C/C++, MicroPython, and Arduino.
It comes with a complete SDK and open-source tutorials, making it easy to get started and quickly embedded into applications.
