SparkFun RedBoard Plus with Qwiic connector

This board combines simplicity of Arduino Uno with communication stability of FTDI chips. On board, there is ATmega328P microcontroller with Optiboot (UNO) bootloader and pinout compatible with Arduino Uno. The changes you will notice when using the module are:

  • USB C connector - the large USB B connector has been replaced with a small, convenient USB C socket
  • Qwiic connector - a convenient Qwiic connector was placed on the board, so there is no need for soldering
  • Bypass jumper - the board includes a jumper to bypass the resetable fuse
  • I/O logic switch - instead of cutting the jumper and soldering the board, you can now flip the switch to match the logic level to the system voltage
  • Two additional analog pins - attached to A6 and A7
  • The board colour has been changed from blue to red

Power supply for SparkFun RedBoard Plus

Module can be powered through USB C cable and external device like AC adapter, battery or accumul ator. Switching the power source is done automatically. The power supply unit is connected to a standard DC socket. Battery or other source is connected to pins ofPOWER connector.

Arduino Uno vs. RedBoard Plus

Similarities Differences

Board selection in Arduino IDE environment - for both chipsets, select Uno module in options.

USB - UART converter - Uno has Atmega16u4 chip with appropriate software, on RedBoard Plus board we have dedicated FTDI FT232 chip.

Digital and analog pins - pins placed in the same way.

Arduino board is made in THT (through hole) technology, RedBoard is made in SMD (surface mounted soldering) technology.

Operating voltage - both modules operate at 5V and have built-in 3,3V voltage regulator.

Digital and analog pins - RedBoard Plus has more pins (A6 and A7)
