DualMCU ONE
The UNIT DualMCU-ONE is a highly versatile development board that integrates the power of two microcontrollers: the ESP32 and the RP2040. Designed for advanced IoT, robotics, and industrial applications, it offers enhanced connectivity, robust power management, and full compatibility with Arduino UNO shields.
The DualMCU-ONE operates with 3.3V logic levels instead of the Arduino Uno’s typical 5V. Make sure any shield or peripheral connected is compatible with 3.3V logic to avoid potential damage.
