uHex Low Power Microcontroller compatible with Arduino

Product Code: AN-03884
Availability: Temporarily Out Of Stock
Ex Tax: 14.13€
The DFRobot module is equipped with the Atmega328P microcontroller compatible with Arduino Pro/Mini. This means that it can be programmed through the Arduino IDE using available libraries. To connect the system with the computer, you will need the USB - UART converter.
The DFRobot module features an Atmega328P microcontroller clocked at 8 MHz. It has 14 digital input/outputs, 6 PWM channels, 8 analog inputs, and communications interfaces. It features with small size and low current consumption - in sleep mode up to 0.12 µA.
Creating and installing software is allowed by the free environment of the Arduino IDE. This board has no system that controls the USB interface. Therefore, for programming necessary is UART - USB adapter.
