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.

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

ESP32-S3-EYE is a small-sized AI development board. It is based on the ESP32-S3 SoC and ESP-WHO, Espressif’s AI development framework. The ESP32-S3-EYE board consists of two parts: the main board (ESP32-S3-EYE-MB) features the ESP32-S3-WROOM-1 module, a 2-Megapixel camera, a SD card slot, a digital microphone, a USB port, and function buttons; and the sub board (ESP32-S3-EYE-SUB) integrates an LCD display. The main board and sub board are connected through pin headers. ESP32-S3-EYE offers plenty of storage, with an 8 MB Octal PSRAM and a 8 MB flash. It also supports image transmission via Wi-Fi and debugging through a Micro-USB port. Specifications Camera The 2 MP camera OV2640 has a 66.5° field of view and a maximum resolution of 1600x1200. You can change the resolution when developing applications. Module Power LED The LED (green) turns on when USB power is connected to the board. If it is not turned on, it indicates either the USB power is not supplied, or the 5 V to 3.3 V LDO is broken. Software can configure GPIO3 to set different LED statuses (turned on/off, flashing) for different statuses of the board. Note: GPIO3 must be set up in open-drain mode. Pulling GPIO3 up may burn the LED. Pin Headers Connect the female headers on the sub board. 5 V to 3.3 V LDO Power regulator that converts a 5 V supply into a 3.3 V output for the module. Digital Microphone The digital I²S MEMS microphone features 61 dB SNR and –26 dBFS sensitivity, working at 3.3 V. FPC Connector Connects the main board and the sub board. Function Button There are six function buttons on the board. Users can configure any functions as needed except for the RST button. ESP32-S3-WROOM-1 The ESP32-S3-WROOM-1 module embeds the ESP32-S3R8 chip variant that provides Wi-Fi and Bluetooth 5 (LE) connectivity, as well as dedicated vector instructions for accelerating neural network computing and signal processing. On top of the integrated 8 MB Octal SPI PSRAM offered by the SoC, the module also comes with 8 MB flash, allowing for fast data access. ESP32-S3-WROOM-1U module is also supported. MicroSD Card Slot Used for inserting a MicroSD card to expand memory capacity. 3.3 V to 1.5 V LDO Power regulator that converts a 3.3 V supply into a 1.5 V output for the camera. 3.3 V to 2.8 V LDO Power regulator that converts a 3.3 V supply into a 2.8 V output for the camera. USB Port A Micro-USB port used for 5 V power supply to the board, as well as for communication with the chip via GPIO19 and GPIO20. Battery Soldering Points Used for soldering a battery socket to connect an external Li-ion battery that can serve as an alternative power supply to the board. If you use an external battery, make sure it has built-in protection circuit and fuse. The recommended specifications of the battery: capacity > 1000 mAh, output voltage 3.7 V, input voltage 4.2 V – 5 V.
