Duo Display Series: Equipped with RP2040 and ESP32 Microcontrollers

Jan 11, 2024 — by Giorgio Mendoza 449 views

SB-Components has recently introduced an innovative range of compact modules on Kickstarter, featuring the RP2040 and ESP32 S3 WROOM-1 microcontrollers. These devices are equipped with a 6-DoF IMU, interchangeable displays, and versatile options for storage and connectivity.

The series showcases two primary models: the Dual Roundy and the Dual Squary. The Dual Roundy boasts a 1.28″ round display with a 240 x 240 resolution. Users have the choice between the RP2040 or the ESP32 S3 WROOM-1 microcontrollers, depending on the performance or wireless capabilities.

For reference, the ESP32 S3 WROOM-1 features a dual-core 32-bit LX7 microprocessor, capable of speeds up to 240 MHz. It also includes an inbuilt 2.4 GHz Wi-Fi (802.11 b/g/n) and a Bluetooth® 5 (LE) module. In contrast, the Raspberry Pi RP2040 features a 32-bit dual ARM Cortex-M0+ processor, running at 133MHz.

The Dual Squary, alternatively, offers a 1.54″ square display (240 x 240 resolution), available with both microcontroller options, and similar onboard peripherals.

Each model in the series stands out for its vibrant displays and a 6-DoF IMU consisting of a 3-axis gyroscope and accelerometer, making them suitable for advanced motion control and interactive projects.

Connectivity is a significant aspect of the Duo Display series. Both models include microSD card slots and USB Type-C interfaces, simplifying programming and data logging.

They are also compatible with MicroPython, CircuitPython, and Arduino for software development, and the series’ HID emulation for mouse and keyboard operations further enhances their versatility.
