Overview

Take your next idea to market with a development board that you can keep in your pocket. With full program and debug capabilities, the ATmega4809 Curiosity Nano Evaluation Kit offers complete support for your next design.

The ATmega4809 microcontroller (MCU) broadens the effectiveness of real-time control systems with a combination of intelligent hardware peripherals alongside the low-power capacity of the AVR core. Elevate your design with a high-speed ADC, Core Independent Peripherals (CIPs), and on-chip Configurable Custom Logic (CCL).

MPLAB X IDEs as a magnifying glass to look into your MCU and step through the debug. Free, easy-to-use graphical programming tool MCC allow you to intuitively program the ATmega4809.

Key Features

  • A board the size of a stick of gum with the power to take your idea to market
  • On-board debugger - no external tools are needed to program the ATmega4809
  • Flexible 8-bit ATmega4809 MCU is perfect for real-time control (and so much more)

Curiosity Nano Explorer

The Curiosity Nano Explorer lives up to its name by providing extensive on-board features that allow users to explore and experiment with the microcontroller peripherals of their Curiosity Nano development board. It also serves as an ideal platform to become familiar with Microchip's software offerings, including MCC Melody.

A wide selection of input and output options:

  • INPUTS include Touch (and mechanical) buttons, a potentiometer, a joystick, a temperature sensor, a proximity sensor, an ambient light sensor, and a microphone

  • OUTPUTS include LEDs (simple yellow, standard RGB, and WS2812B RGB), an OLED display, and a speaker 

Solid support for serial communication:

  • I2C Bus with eight clients
  • SPI Bus with three clients
  • UART connection

Microchip’s complementary technologies:

  • Touch controller with three touch buttons and a separate touch button for use with microcontrollers featuring a touch peripheral
  • ECC608 provides CryptoAuthentication™ features
  • Power Monitoring by the PAC1944 enables the measurement of various power domains

Finally, if anything is missing on the Explorer, its functionality can be expanded via mikroBUS™, Grove or Qwiic® sockets.
