Product Description

Overview

The Pololu A-Star 32U4 Mini boards are general-purpose programmable modules based on the ATmega32U4 AVR microcontroller from Microchip (formerly Atmel), which has 32 KB of flash program memory, 2.5 KB of RAM, and built-in USB functionality. The A-Star (abbreviated A*) adds a number of onboard features to support the microcontroller and make it easier to work with, including a 16 MHz crystal, a USB Micro-B connector, an in-system programming (ISP) header, a reset button, and three indicator LEDs.

This version, the A-Star Mini SV, can be powered from a 5 V to 40 V external source. The input voltage is regulated to 5 V by an 800 mA ISL85418 switching step-down (buck) converter from Renesas (which acquired Intersil). (We also make standalone regulators based on the 500 mA and 1 A versions of this integrated circuit.)

Features

Dimensions: 1.9? × 0.7? (1.95? × 0.7? including USB Micro-B connector)
Programmable 16 MHz ATmega32U4 AVR microcontroller
- 32 KB flash (4 KB used by bootloader, leaving 28 KB available for user program by default)
- 2.5 KB SRAM
- 1 KB EEPROM
- Native full-speed USB (12 Mbps)
Preloaded with Arduino-compatible bootloader (no external programmer required)
All I/O lines from the ATmega32U4 broken out in a compact package

Notes:

1.Without included optional headers. This measurement includes the USB Micro-B connector, which extends 0.05? past the edge of the PCB.
2.Without included optional headers.
3.Note that 4 KB of the MCU's 32 KB of flash memory is used by the pre-installed USB bootloader. All 32 KB is available when programming via the ISP header rather than the bootloader.
4.For light loads. The regulator's dropout voltage increases approximately linearly with the load, from a few millivolts at no load up to around 0.6 V at 500 mA.
5.Available current depends on input voltage, current consumed by the board, ambient conditions, and regulator topology. See product documentation and performance graphs for details.
6.On Bat+ (LV, SV) or Bat- (ULV).
