The PTSolns Uno R3+ based on the ATmega328P, is a popular microcontroller development board with additional unique features. The Uno R3+ continues to be compatible with a range of shields, yet it has two extra female header pins. These pins are used to supply SDA and SCL that are shifted from the onboard logic level of 5 V down to 3.3 V. Along with the onboard QWIIC connector, this shifted 3.3 V I2C bus makes it convenient to connect many common sensors and modules that operate on 3.3 V logic No need for extra external components, all the logic level shifting between 5 V and 3.3 V on the I2C bus is done automatically onboard.

The Uno R3+ replaces the previous bulky port with a modern USB-C port. Meanwhile the standard power barrel jack remains onboard. The board has a new layout of components, such as for example, the grouping of the four LEDs (Power LED, Pin 13 controlled LED, TX and RX communication LEDs). Furthermore, the Uno R3+ allows for a larger current draw on the 3.3 V pin with a rated maximum of 0.8A. This lets the user manage their project’s power budget more easily by allowing a larger current draw. 

This version of the Uno R3+ contains the ATmega328P as a 28-Pin through-hole component that can be removed from the board and used elsewhere, as in for example the popular entry-level project “Make Your own Uno”. The Uno R3+ comes with a pre-installed out-of-the-box ready set of tests. This gets simple projects started quickly and allows for testing the proper function of the board. A large active online community supports this microcontroller and its programming using the Arduino IDE software. Many tutorials, projects, schematics, and sketches can be easily found online in blogs, forums and the like. 

This Plus version offers all of the features users come to learn and expect, and adds additional ones that make this board stand out.

All Uno R3+ boards are individually inspected and marked with a quality control sticker (either on the PCB, or on the packaging).

The Uno R3+ is compatible with a range of shields, including the Proto-Shield, the NRF-Shield, the Interface-Shield.
