Dual Roundy display modules powered by Raspberry Pi RP2040 or ESP32-S3 microcontrollers. These compact modules feature a 6-DoF IMU, interchangeable displays, and multiple storage and connectivity options.
The Dual Roundy is equipped with two 1.28-inch round displays, with a 240 x 240 resolution, and uses the GC9A01 display driver IC. Both displays offer a choice between a Raspberry Pi RP2040 MCU and the ESP32-S3-WROOM-1 module catering to different needs in performance and wireless capabilities.
Features Of Dual Roundy ESP32:
- Powered by ESP32 S3 Wroom-1 microcontroller module
- Dual 1.28” Round display arrangement for creative visual interactions
-
Board features an array of four WS2812B RGB Led with true 16M color support
- Onboard QMI8658C 6D MEMS inertial measurement unit, incorporates a 3-axis gyroscope and a 3- axis accelerometer
- Power and Charging LED for status indication
- Battery hookup and charging facilities for portability
- Onboard microSD card support for data logging purposes
- Multipurpose GPIOs breakout for additional peripheral interfacing
- Boot and Reset Button for programming
- Type C interface for power and programming purpose
- Two User Programmable Buttons to add additional controls to project
- Supports cross platform development with multiple programming languages like Arduino, C/C+ and MicroPython
