Based on STM32H747, Arduino® Nicla vision development board schematic

Arduino® Nicla Vision is a ready-to-use standalone camera for analyzing and processing images at the edge. It's suitable for asset tracking, object recognition and predictive maintenance thanks to its 2MP color camera, smart 6-axis motion sensor, integrated microphone and distance sensor. Quickly implement sensor nodes that send collected data to the Arduino® Cloud (or third-party vendor service) via integrated WiFi/BLE connectivity.

Wigl Kit: Create your own music-loving robot (including schematics, source code, etc.)

Wigl can hear the notes of any instrument and respond with movements, lights and special dances! Wigl helps motivate children and adults to practice their instruments. By sequencing the notes, you can program special dance moves for your Wigl. This combination of right-brain creativity and left-brain logic makes it a unique robot for any home. How does WIG work? Wigl has a microphone, a microcontroller (brain) and some motors for movement. Wigl is always listening for notes, and through some complex math it can hear individual notes.

The most powerful T12 integrated portable soldering iron with gyroscope and buzzer, PD power supply

Built-in gyroscope, buzzer, supports multiple fast charging protocols, 128x64 OLED screen, standard T12 fixed bayonet. Regarding the problem of grounding the soldering iron, you can use the PD power supply of Mac and prepare a triangle extension cable to solve the problem perfectly. Or using a power bank directly is not a big problem.

Smart wearable devices based on RSL10

A smart wearable device based on the RSL10 development board officially provided by EEWORLD. This device is divided into two parts: the host and the slave. However, this MCU only has one UART, but in actual project requirements we need to use two UARTs. The organizer of this event gave five boards, so a board without a sensor is used as the SPI slave and will receive The command parses and uses AT commands to control the audio.
