MKR WAN 1300 is a powerful board that combines the functionality of the MKR Zero and LoRa / LoRaWAN^TM connectivity. It is the ideal solution for makers wanting to design IoT projects with minimal previous experience in networking having a low power device.

Arduino MKR WAN 1300 has been designed to offer a practical and cost effective solution for makers seeking to add Lo-Ra connectivity to their projects with minimal previous experience in networking. It is based on the Atmel SAMD21 and a Murata  CMWX1ZZABZ Lo-Ra module.

The design includes the ability to power the board using two 1.5V AA or AAA batteries or external 5V. Switching from one source to the other is done automatically. A good 32 bit computational power similar to the MKR ZERO board, the usual rich set of I/O interfaces, low power Lo-Ra communication and the ease of use of the Arduino Software (IDE) for code development and programming. All these features make this board the preferred choice for the emerging IoT battery-powered projects in a compact form factor. The USB port can be used to supply power (5V) to the board. The Arduino MKR WAN 1300 is able to run with or without the batteries connected and has limited power consumption.

Warning: Unlike most Arduino & Genuino boards, the MKR WAN 1300 runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board. While output to 5V digital devices is possible, bidirectional communication with 5V devices needs proper level shifting.

The Arduino Nano 33 BLE Sense Rev2 with headers is Arduino’s 3.3V AI enabled board in the smallest available form factor with a set of sensors that will allow you without any external hardware to start programming your next project, right away.

With the Arduino Nano 33 BLE Sense Rev2, you can:

• Build wearable devices that using AI can recognize movements.
• Build a room temperature monitoring device that can suggest or modify changes in the thermostat.
• Build a gesture or voice recognition device using the microphone or the gesture sensor together with the AI capabilities of the board.

The main feature of this board, besides the complete selection of sensors, is the possibility of running Edge Computing applications (AI) on it using TinyML. Learn how to use the Tensor Flow Lite library following this instructions or learn how to train your board using Edge Impulse.

With the MKR Vidor 4000 you can configure it the way you want; you can essentially create your own controller board. It comes loaded with hardware and potential: an 8 MB SRAM; a 2 MB QSPI Flash chip — 1 MB allocated for user applications; a Micro HDMI connector; an MIPI camera connector; and Wifi & BLE powered by U-BLOX NINA W10 Series. It also includes the classic MKR interface on which all pins are driven both by SAMD21 and FPGA. Plus, it has a Mini PCI Express connector with up to 25 user programmable pins.

The FPGA contains 16K Logic Elements, 504 KB of embedded RAM, and 56 18x18 bit HW multipliers for high-speed DSP. Each pin can toggle at over 150 MHz and can be configured for functions such as UARTs, (Q)SPI, high resolution/high frequency PWM, quadrature encoder, I2C, I2S, Sigma Delta DAC, etc.

The on-board FPGA can be also used for high-speed DSP operations for audio and video processing. This board also features a Microchip SAMD21. Communication between FPGA and the SAMD21 is seamless.

The Arduino GIGA R1 WiFi is designed for ambitious makers who want to step up their game. It levels the playing field for gamers, artists, sound designers and anyone coming to the tech world with big ideas on a budget – because it packs advanced features into an accessible component, with the same form factor as our popular Mega and Due.

Let’s break down all the powerful features of this board.

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.

Hardware ports and communication: Following the legacy of the Arduino Mega and the Arduino Due, the GIGA R1 WiFi has 4 UARTs (hardware serial ports), 3 I2C ports (1 more than its predecessors), 2 SPI ports (1 more than its predecessors), 1 FDCAN.

GPIOs and extra pins: We wanted to keep the same form factor of the Mega and the Due, so you can easily adapt your custom made shields to the GIGA R1 WiFi (remember this board works at 3.3V though!) and we added extra headers to access extra pins, leaving the total count to 76 GPIO pins, and the best part, you can access them from underneath, so keep your project as it is and just think on how to expand it. Also, we added two new pins: a VRTC so you can connect a battery to keep the RTC running while the board is off and an OFF pin so you can shut down the board.

Connectors: The GIGA R1 WiFi has extra connectors on board which will facilitate the creation of your project without any extra hardware. This board has:

• USB-A connector suitable for hosting USB sticks, other mass storage devices and HID devices such as keyboard or mouse.
• 3.5mm input-output jack connected to DAC0, DAC1 and A7.
• USB-C® to power and program the board, as well as simulate an HID device such as mouse or keyboard.
• Jtag connector, 2x5 1.27mm.
• 20 pin Arducam camera connector.

Higher voltage support: In comparison with its predecessors that support up to 12 volts, the GIGA R1 WiFi can handle a range of 6 to 24 volts.
