The A-Star 32U4 Micro breaks out 15 general-purpose I/O lines along two rows of pins, including 7 usable as PWM outputs and 8 usable as analog inputs. It fits all this into a 20-pin dual in-line package (DIP) measuring only 1″ × 0.6″ (even smaller than competing ATmega32U4 boards like the Teensy 2.0 and Pro Micro), and its 0.1″ pin spacing makes the A* easy to use with 0.1″-pitch connectors.

The A-Star 32U4 ships with a preloaded Arduino compatible bootloader (which uses 4 KB of flash memory, leaving 28 KB available for the user program). We provide a software add-on that enables the board to be easily programmed from the Arduino environment. The A-Star 32U4 uses the same microcontroller as the

The board can either be powered directly from the USB 5 V supply or from a separate 5.5 V to 15 V source on the VIN pin, which is reduced to 5 V by a 100 mA low-dropout (LDO) regulator; you can access this 5 V supply through the 5V power output pin. Additionally, the ATmega32U4 contains an internal 3.3 V regulator whose output is available on the 3V3 pin. Current drawn from the 3V3 output should not exceed about 50 mA, and when the board is being powered through VIN, the sum of the 5V output current, 3V3 output current, GPIO output current, and current used by the board itself (typically about 25 mA) should not exceed 100 mA.

The A-Star 32U4 Prime LV is a programmable board based on the ATmega32U4 AVR microcontroller and arranged in the common Arduino form factor. The A-Star Prime offers many additional features and improvements over competing products, including superior power management that enables efficient operation from2 V to 16 V(though it requires at least 3 V at start-up).

This configuration of the A-Star 32U4 Prime LV includesmicroSD supportand isassembled with through-hole componentsas shown in the picture above so that all the basic features can be used without any additional soldering. The standard female headers common to many Arduinos are preinstalled, as is the 2×3 male ISP header, buzzer, DC power jack, and shorting block headers for enabling the microSD hardware, buzzer, and battery voltage monitor.

The Pololu A-Star 32U4 Prime is a general-purpose programmable board based on the ATmega32U4 AVR microcontroller from Microchip (formerly Atmel) and arranged in the common Arduino form factor exemplified by theUno R3andLeonardo.

The ATmega32U4 is capable of native full-speed USB, which makes it more versatile than similar boards that rely on USB-to-serial adapters: in addition to supporting a virtual (CDC) serial/COM port interface, the A-Star can appear to a connected computer as a mouse and keyboard. The A-Star’s USB interface can be accessed through its USB Micro-B connector.

All 26 general-purpose I/O lines from the ATmega32U4 are broken out (including PB0, PD5, and PE2); 7 of these can be used as hardware PWM outputs and 12 of these can be used as analog inputs

The A-Star 32U4 has the same microcontroller and form factor as the Arduino Leonardo, and it runs at the same frequency, so we generally expect it to work with shields that are compatible with the Leonardo and similar boards. Note that the Prime has additional components and connection points, so you should make sure these do not physically interfere with any shield you are considering using.

The standard female headers common to many Arduinos are preinstalled, as is the 2×3 male ISP header, buzzer, DC power jack, and shorting block headers for enabling the microSD hardware, buzzer, and battery voltage monitor. This is the LV version of the A-Star Prime, which operates from 2 V to 16 V.

This newer version (ac03e) of the A-Star 32U4 Prime LV replaces the original version (ac03b). The new version uses an improved 5 V regulator that can deliver more current and operates from 2 V to 16 V instead of 2.7 V to 11.8 V. The easiest way to distinguish between the two versions is via the silkscreen on the bottom side of the board, above and to the left of the Pololu logo, where the original version is labeled ac03b and the new version is labeled ac03e.

The newer ac03e version has an improved regulator that operates from 2 V to 16 V and can deliver more current.

A major feature of the A* Prime LV is its power system, which allows it to efficiently operate from a 2.7 V to 11.8 V external source. Like on the smaller A-Star 32U4 Mini LV, the input voltage is regulated to 5 V by a TPS63061 switching step-up/step-down (buck-boost) converter from Texas Instruments. (We also make a standalone regulator based on this integrated circuit.) The regulator’s flexibility in input voltage is especially well-suited for battery-powered applications in which the battery voltage begins above 5 V and drops below 5 V as the battery discharges. Without the typical restriction on the battery voltage staying above 5 V throughout its life, a wider range of battery types can be considered. For example:

This TFT display is 4.0" diagonal with a bright 4 white-LED backlight with a resolution of 480x320. It has way more resolution than a black and white 128x64 display. As a bonus, this display comes with a resistive touchscreen attached to it already, so you can use the stylus on the screen.

The Adafruit 1.3" Color TFT Bonnet for Raspberry Pi has 240x240 color pixels in an IPS TFT display controlled over SPI. This display is super small, only about 1.3" diagonal, but since it is an IPS display, it"s very readable with high contrast and visibility.

With the TFT display in the center, Adafruit had some space on either side so they added a 5-way joystick and two pushbuttons. Great for when you want to have a control interface for your project. Using the display is very easy, Adafruit have a kernel driver and Python library for the ST7789 chipset. You can set it up as a console output so you can have text and user interface through the Raspberry Pi OS or you draw images, text, whatever you like, using the Python imaging library. Adafruit also have Python code you can use to read the joystick and buttons.

The A-Star 32U4 Micro is a tiny programmable module featuring Atmel’s ATmega32U4 microcontroller. It packs a Micro-USB interface and 15 digital input/output pins (of which 7 can be used as PWM outputs and 8 as analog inputs) onto a board measuring only 1″ × 0.6″ and comes preloaded with an Arduino-compatible bootloader.

The Pololu A-Star 32U4 Micro is a general-purpose programmable module based on Atmel’s ATmega32U4 AVR microcontroller, which has 32 KB of flash program memory, 2.5 KB of RAM, and built-in USB functionality. Onboard features of the A-Star (abbreviated A*) include a 16 MHz resonator, a USB Micro-B connector, an in-system programming (ISP) header, and a pair of indicator LEDs. A voltage regulator and power selection circuit allow the board to be powered from either USB or an external 5.5 V to 15 V source, while a resettable PTC fuse on the USB VBUS supply and reverse protection on VIN help protect it from accidental damage.

The A-Star 32U4 Micro breaks out 15 general-purpose I/O lines along two rows of pins, including 7 usable as PWM outputs and 8 usable as analog inputs. It fits all this into a 20-pin dual in-line package (DIP) measuring only 1″ × 0.6″ (even smaller than competing ATmega32U4 boards like the Teensy 2.0 and Pro Micro), and its 0.1″ pin spacing makes the A* easy to use with solderless breadboards, perfboards, and 0.1″-pitch connectors.

The A-Star 32U4 ships with a preloaded Arduino-compatible bootloader (which uses 4 KB of flash memory, leaving 28 KB available for the user program). We provide a software add-on that enables the board to be easily programmed from the Arduino environment.

The A-Star 32U4 uses the same microcontroller as the Arduino Leonardo and Arduino Micro and runs at the same frequency, making it just as powerful. Although the larger boards offer a few more I/O pins, the A-Star 32U4 Micro fits in an area half that of the Arduino Micro, and it takes up only 11% as much area as a standard full-size Arduino!

This diagram identifies the I/O and power pins on the A-Star 32U4 Micro; yellow labels represent digital I/O pins and green labels represent analog input channels. Light text on a dark background indicates Arduino digital and analog pin numbering, while dark text on a light background indicates a name or function of the pin as defined in the ATmega32U4 datasheet. For more information about the ATmega32U4 microcontroller on this board, see Atmel’s ATmega32U4 documentation.

The board can either be powered directly from the USB 5 V supply or from a separate 5.5 V to 15 V source on the VIN pin, which is reduced to 5 V by a 100 mA low-dropout (LDO) regulator; you can access this 5 V supply through the 5V power output pin. Additionally, the ATmega32U4 contains an internal 3.3 V regulator whose output is available on the 3V3 pin. Current drawn from the 3V3 output should not exceed about 50 mA, and when the board is being powered through VIN, the sum of the 5V output current, 3V3 output current, GPIO output current, and current used by the board itself (typically about 25 mA) should not exceed 100 mA.

A 1×20-pin breakaway 0.1″ male header is included with the A-Star 32U4 Micro, which can be soldered in to use the board with perfboards, breadboards, or 0.1″ female connectors. (The headers might ship already separated into two 1×10 pieces.) Also included is a 2×3 header that can be installed to allow external programming of the microcontroller through the AVR ISP interface, such as with our USB AVR programmer.
