Wouldn't it be cool to drive a tiny OLED display, read a color sensor, or even just flash some LEDs directly from your computer? Sure you can program an Arduino or Trinket to talk to these devices and your computer, but why can't your computer just talk to those devices and sensors itself? Well, now your computer can talk to devices using the Adafruit FT232H breakout board! What can the FT232H chip do? This chip from FTDI is similar to their USB to serial converter chips but adds a 'multi-protocol synchronous serial engine' which allows it to speak many common protocols like SPI, I²C, serial UART, JTAG, and more! There's even a handful of digital GPIO pins that you can read and write to do things like flash LEDs, read switches or buttons, and more. The FT232H breakout is like adding a little swiss army knife for serial protocols to your computer! This chip is powerful and useful to have when you want to use Python (for example) to quickly iterate and test a device that uses I²C, SPI or plain general purpose I/O. There's no firmware to deal with, so you don't have to deal with how to 'send data to and from an Arduino which is then sent to and from' an electronic sensor or display or part. This breakout has an FT232H chip and an EEPROM for onboard configuration. Specifications Dimensions: 23 x 38 x 4 mm (0.9 x 1.5 x 0.2') Weight: 3.4 g Downloads CAD Files

Portenta H7 Lite allows you to build your next smart project. Ever wanted an automated house? Or a smart garden? Well, now it’s easy with the Arduino IoT Cloud compatible boards. It means: you can connect devices, visualize data, control and share your projects from anywhere in the world. The Portenta H7 Lite is very similar to the Portenta H7, that simultaneously can run high level code along with real time tasks thanks to its two processors. It is, for example, possible to execute Arduino compiled code along with MicroPython one and have both cores to communicate with one another. However, the H7 Lite is a low-cost board with H7 functionalities that can be configured to specific use cases. Features Dual Core – Two best-in-class processors in one, running parallel tasks AI on the edge – So powerful it can run AI state machines Customization – The board is highly customizable in volumes High-level programming language support (Micropython) The Portenta H7 Lite offers twofold functionality: it can run either like any other embedded microcontroller board, or as the main processor of an embedded computer. For example, use the Portenta Vision Shield to transform your H7 Lite into an industrial camera capable of performing real-time machine learning algorithms on live video feeds. As the H7 Lite 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 carries out low-level operations like controlling a motor or acting as a user interface. Solutions High-end industrial machinery Laboratory equipment Computer vision PLCs Robotics controllers Mission-critical devices High-speed booting computation (ms) Two Parallel Cores The Portenta H7 Lite’s main processor is the STM32H747 dual core 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 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: simply upgrade your Portenta board to the one suiting your needs.

The Arduino MKR Zero is a development board for music makers! With an SD card holder and dedicated SPI interfaces (SPI1), you are able to play music files without extra hardware. The MKR Zero brings you the power of a Zero in the smaller format established by the MKR form factor. The MKR Zero board acts as a great educational tool for learning about 32-bit application development. It has an on-board SD connector with dedicated SPI interfaces (SPI1) that allows you to play with MUSIC files with no extra hardware! The board is powered by Atmel’s SAMD21 MCU, which features a 32-bit ARM Cortex M0+ core. The board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it by a LiPo battery. The battery voltage can also be monitored since a connection between the battery and the analog converter of the board exists. Specifications Microcontroller SAMD21 ARM Cortex-M0+ 32-bit low power Board power supply (USB/VIN) 5 V Supported battery Li-Po single cell, 3.7 V, 700 mAh minimum DC current for 3.3 V pin 600 mA DC current for 5 V pin 600 mA Circuit operating voltage 3.3 V Digital I/O pins 22 PWM pins 12 (0, 1, 2, 3, 4, 5, 6, 7, 8, 10, A3 - or 18 -, A4 -or 19) UART 1 SPI 1 I²C 1 Analog input pins 7 (ADC 8/10/12 bit) Analog output pins 1 (DAC 10 bit) External interrupts 10 (0, 1, 4, 5, 6, 7, 8, A1 -or 16-, A2 - or 17) DC current per I/O pin 7 mA Flash memory 256 KB Flash memory for bootloader 8 KB SRAM 32 KB EEPROM No Clock speed 32.768 kHz (RTC), 48 MHz LED_BUILTIN 32 Downloads Datasheet Eagle Files Schematics Fritzing Pinout

The iCEBreaker FPGA board is an open-source educational FPGA development board. The iCEBreaker is great for classes and workshops teaching the use of the open source FPGA design flow through Yosys, nextpnr, IceStorm, Icarus Verilog, Amaranth HDL and others. This means the board is low cost and has a nice set of features to allow for the design of interesting classes and workshop exercises. At the same time it allows the user to use the proprietary vendor tools if they choose to. After the workshop the boards can be easily used as a development board as most GPIO are exposed, broken out and configurable through jumpers on the back of the board. There is only a minimal amount of buttons and LED that can't be disconnected and used for your own purposes. Documentation Workshop

Arduino MKR NB 1500 allows you to build your next smart project. Ever wanted an automated house? Or a smart garden? Well, now it’s easy with the Arduino IoT Cloud compatible boards. It means: you can connect devices, visualize data, control and share your projects from anywhere in the world. Whether you’re a beginner or a pro, we have a wide range of plans to make sure you get the features you need. Add Narrowband communication to your project with the MKR NB 1500. It's the perfect choice for devices in remote locations without an Internet connection, or in situations in which power isn't available like on-field deployments, remote metering systems, solar-powered devices, or other extreme scenarios. The board's main processor is a low power ARM Cortex-M0 32-bit SAMD21, like in the other boards within the Arduino MKR family. The Narrowband connectivity is performed with a module from u-blox, the SARA-R410M-02B, a low power chipset operating in the de different bands of the IoT LTE cellular range. On top of those, secure communication is ensured through the Microchip ECC508 crypto chip. Besides that, the pcb includes a battery charger, and a connector for an external antenna. This board is designed for global use, providing connectivity on LTE's Cat M1/NB1 bands 1, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26, 28. Operators offering service in that part of the spectrum include: Vodafone, AT&T, T-Mobile USA, Telstra, and Verizon, among others.
