RGB Base V1.0 Expansion Board

The RGB Base V1.0 is a Duino-compatible expansion board measuring 68.58 x 54.86 mm. It operates from a DC5V input and adds I2C and UART ports for connecting addressable LEDs and other peripherals. The board is designed for hobbyists and professionals who want to integrate lighting effects into 3D printed projects. No retail packaging is included.

Builders adding RGB lighting to prints

This board suits makers who need a compact way to drive RGB LEDs from a Duino controller using I2C or UART. It provides 11 common-function pins alongside four I2C channels and one UART channel. Builders who require a higher supply voltage, a different microcontroller ecosystem, or more than 11 general-purpose connections should look at other solutions.

DC5V operating voltage

The single specification that decides fit is the 5V supply requirement; the board must be powered from a regulated 5V source. It exposes four I2C ports, one UART port and 11 common-function pins for peripheral wiring. Physical dimensions are 68.58 x 54.86 mm.

Questions about this item

Should I choose the V1.0 board or wait for a later revision?

Only the V1.0 revision is listed, so there is no newer version to compare.

What does the DC5V input mean for my printer setup?

The board runs on 5 V DC, matching the logic voltage of standard Duino boards.

How many devices can I connect through the I2C and UART ports?

Four I2C ports and one UART port are provided, plus eleven common-function sockets.
