ATmega32U4 Microcontroller Board Products

Description

The ATmega32U4 is a popular micrcontroller that has the same processing power as the ATmega328P with an 8-bit 16MHz AVR ATmega (max speed 20MHz) and Advanced RISCReduced Instruction Set Computer architecture. The ATmega32U4 distinguishes itself from the ATmega328P with the following features:

• Built-in USB controller, which allows it to operate as a USB device without the need for an external USB-to-serial converter
• More GPIOGeneral Purpose Input Output pins and ADCAnalog-to-Digital Converter (ADC, A/D, or A-to-D) channels.
• More RAM, with 2.5KB of SRAMStatic Random Access Memory compared to the ATmega328p's 2KB of SRAM
• Less power consumption

Both prototyping and small footprint boards with the ATmega32U4 microcontroller are available.
