A standout feature of the Metro RP2350 is its adherence to the Arduino UNO's design, allowing users to leverage a vast ecosystem of compatible shield expansions. While the board operates at a logic ...

If not using an Arduino Uno board, use a USB-to-TTL serial converter card to program the ATmega328P. Connect the receiver pin (RXD) of the converter to the transmitter pin (TXD) of the microcontroller ...

When you think of Arduino, your mind immediately pictures an Arduino Uno with its teal color, bulky USB port, and long microcontroller chip sitting on a socket, and you're not alone.

This port is primarily used for connecting the board to the computer for tasks such as monitoring serial data received or produced by the Arduino. However, the USB port doubles as a power port.

Both versions of the Uno R4 offer 32 kbytes of SRAM and 256 kbytes of flash memory. They also furnish a USB-C port, along with CAN bus, SPI, and I2C communication capabilities. In addition, each Uno ...

Software scalability is also supported on the new board, allowing easy upgrades for projects made with UNO R3 or Leonardo. Arduino said requests from the Arduino community see the USB port upgraded to ...

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

Requests from the Arduino community see the USB port upgraded to USB-C® and the maximum power supply voltage increased to 24 V with an improved thermal design.

The UNO R4 Minima board is of similar design complexity as the R3. The UNO R4 WiFi is a denser board as it uses the empty board space of the Minima for an 8 by 12 LED matrix and an ESP32-S3-MINI-1 ...
