The Arduino Giga R1 WiFi brings the power of the STM32H7 to the same form factor as the popular Mega and Due, being the first Mega board to include onboard Wi-Fi and Bluetooth connectivity. The board provides 76 digital inputs/outputs (12 with PWM capability), 14 analog inputs and 2 analog outputs (DAC) all easily accessible via pin headers. The STM32 microprocessor with dual-core Cortex-M7 and Cortex-M4, together with onboard memory and audio jack enables you to perform machine learning and signal processing on the edge. Microcontroller (STM32H747XI) This dual core 32-bits microcontroller allows you have two brain talking to each other (a Cortex-M7 at 480 MHz and a Cortex-M4 at 240 MHz) you can even run micropython in one and Arduino in the other. Wireless communication (Murata 1DX) Whether you prefer Wi-Fi or Bluetooth, the Giga R1 WiFi got you covered. You can even quickly connect to the Arduino IoT Cloud and keep track of your project remotely. And if you are concerned about the security of the communication, the ATECC608A keeps everything under control.

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one. The Nano was designed and is being produced by Gravitech. Specifications Microcontroller ATmega328 Operating Voltage (logic level) 5 V Input Voltage (recommended) 7-12 V Input Voltage (limits) 6-20 V Digital I/O Pins 14 (of which 6 provide PWM output) Analog Input Pins 8 DC Current per I/O Pin 40 mA Flash Memory 16 KB (ATmega168) or 32 KB (ATmega328) of which 2 KB used by bootloader SRAM 1 KB (ATmega168) or 2 KB (ATmega328) EEPROM 512 bytes (ATmega168) or 1 KB (ATmega328) Clock Speed 16 MHz Dimensions 0.73 x 1.70' (18 x 45 mm) Power The Arduino Nano can be powered via the Mini-B USB connection, 6-20 V unregulated external power supply (pin 30), or 5 V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source. Memory The ATmega168 has 16 KB of flash memory for storing code (of which 2 KB is used for the bootloader), 1 KB of SRAM and 512 bytes of EEPROM The ATmega328 has 32 KB of flash memory for storing code, (also with 2 KB used for the bootloader), 2 KB of SRAM and 1 KB of EEPROM. Input and Output Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 V. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Communication The Arduino Nano has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega168 and ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1). A SoftwareSerial library allows for serial communication on any of the Nano's digital pins. Programming The Arduino Nano can be programmed with the Arduino software (download). The ATmega168 or ATmega328 on the Arduino Nano comes with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files). You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar; see these instructions for details. Automatic (Software) Reset Rather than requiring a physical press of the reset button before an upload, the Arduino Nano is designed in a way that allows it to be reset by software running on a connected computer. One of the hardware flow control lines (DTR) of theFT232RL is connected to the reset line of the ATmega168 or ATmega328 via a 100 nF capacitor. When this line is asserted (taken low), the reset line drops long enough to reset the chip. The Arduino software uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well-coordinated with the start of the upload.

Portenta H7 follows the Arduino MKR form factor, but enhanced with the Portenta family 80-pin high-density connector. Program it with high-level languages and AI while performing low-latency operations on its customizable hardware. Portenta H7 simultaneously runs high level code along with real time tasks. The design includes two processors that can run tasks in parallel. For example, is possible to execute Arduino compiled code along with MicroPython one, and have both cores to communicate with one another. The Portenta functionality is two-fold, it can either be running like any other embedded microcontroller board, or as the main processor of an embedded computer. Portenta can easily run processes created with TensorFlow Lite, you could have one of the cores computing a computer vision algorithm on the fly, while the other could be making low-level operations like controlling a motor, or acting as a user interface. Use Portenta when performance is key, among other cases, we envision it to be part of: High-end industrial machinery Laboratory equipment Computer vision PLCs Industry-ready user interfaces Robotics controller Mission-critical devices Dedicated stationary computer High-speed booting computation (ms) Two Parallel Cores H7's main processor is the dual core STM32H747 including a Cortex M7 running at 480 MHz and a Cortex-M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly. Both processors share all the in-chip peripherals and can run: Arduino sketches on top of the ARM Mbed OS Native Mbed applications MicroPython / JavaScript via an interpreter TensorFlow Lite Graphics Accelerator Probably one of the most exciting features of the Portenta H7 is the possibility of connecting an external monitor to build your own dedicated embedded computer with a user interface. This is possible thanks to the STM32H747 processor's on-chip GPU, the Chrom-ART Accelerator. Besides the GPU, the chip includes a dedicated JPEG encoder and decoder. A new standard for pinouts The Portenta family adds two 80-pin high density connectors at the bottom of the board. This ensures scalability for a wide range of applications by simply upgrading your Portenta board to the one suiting your needs. On-board Connectivity The onboard wireless module allows to simultaneously manage WiFi and Bluetooth connectivity. The WiFi interface can be operated as an Access Point, as a Station or as a dual mode simultaneous AP/STA and can handle up to 65 Mbps transfer rate. Bluetooth interface supports Bluetooth Classic and Bluetooth Low Energy. It is also possible to expose a series of different wired interfaces like UART, SPI, or I²C, both through some of the MKR styled connectors, or through the new Arduino industrial 80-pin connector pair. The 80-pin connector pair provides additional features including Ethernet. USB-C Multipurpose Connector The board's programming connector is a USB-C port that can also be used to power the board, as a USB Hub, to connect a DisplayPort monitor, or to deliver power to OTG connected devices.

As always with Arduino, every element of the platform – hardware, software, and documentation – is freely available and open-source. This means you can learn exactly how it's made and use its design as the starting point for your own circuits. Hundreds of thousands of Arduino Boards are already fueling people’s creativity all over the world, every day. The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the internet. It is based on the Wiznet W5500 Ethernet chip. The Wiznet W5500 provides a network (IP) stack capable of both TCP and UDP. It supports up to eight simultaneous socket connections. Use the Ethernet library to write sketches that connect to the Internet using the Shield. The Ethernet Shield 2 connects to an Arduino Board using long wire-wrap headers extending through the Shield. This keeps the pin layout intact and allows another Shield to be stacked on top of it. The most recent revision of the board exposes the 1.0 pinout on rev 3 of the Arduino UNO Board. The Ethernet Shield 2 has a standard RJ-45 connection, with an integrated line transformer and Power over Ethernet enabled. There is an onboard micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega (using the Ethernet library). The onboard micro-SD card reader is accessible through the SD Library. When working with this library, SS is on Pin 4. The original revision of the Shield contained a full-size SD card slot; this is not supported. The Shield also includes a reset controller, to ensure that the W5500 Ethernet module is properly reset on power-up. Previous revisions of the Shield were not compatible with the Mega and needed to be manually reset after power-up.
