Hello everyone! Allow us to introduce the Boboduino Uno R3 board!
This board is inspired by the Arduino Uno R3 board and boasts the following additional features:
Built-in Lithium-ion Battery Charger: Power your projects on the go with the Boboduino Uno R3's built-in battery charging IC.
USB Type-C Port: The Boboduino Uno R3 features a modern USB Type-C port for easy connection to your computer or other devices.
5V/3.3V Switch: Easily toggle between 5V and 3.3V power output to support a wider range of sensors and actuators.
This board is especially useful if you are planning to build a portable project with a LiPo battery, as it includes battery charging functionality and can also power on your projects.
Additionally, by adopting the Atmega328PB chip, the board comes with an extra set of I2C, SPI, and UART interfaces, along with more PWM pins.
Please take a look if you are interested in this funny 3rd party board~
Yes, it will be released soon after we organize it! We are also planning to write some articles and maybe make some videos to explain it. As for the articles, they can basically be divided into a few parts:
How the eFuse IC (TPS259631) is used to regulate the input voltage.
How the LiPo battery charging IC (TP5400/TP5410) can be used to charge the battery.
Where the 5V buck-boost converter (RT6150B) plays a role in this board.
The schematics of the Atmega328PB.
The schematics of the CH340G USB-to-serial converter chip.
The battery reverse polarity protection circuit and how it works.
Other special designs on this board.
We look forward to sharing this information with everyone soon.
I, and I'm sure others, await further information. One of the strong attractions of the Arduino line is the transparency of proper schematic availability, and design aids and information.
