About the LuminaBlossom PCB

LuminaBlossom is an open source RP2040/RP2350 PCB design by LunarEchoo56, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 61.5 × 59.5 mm, with 7 components from 7 distinct parts.

Its main chip is the Pico left pins 1-20, from the RP2040/RP2350 family. Other key parts include the SN74AHCT125N. By type, the board carries 3 connectors, 2 capacitors, 1 IC and 1 resistor.

It belongs with the displays & leds and iot & wireless designs in this gallery.

From the project

Wi-Fi-enabled programmable LED light display - Raspberry Pi Pico 2W, 16-pixel RGBW NeoPixel ring, browser-based control surface.

This is a new carrier / interconnect PCB for the existing LuminaBlossom architecture. It is not a custom NeoPixel ring board and is not claimed to be fabricated or tested.

LuminaBlossom: common questions

What microcontroller does the LuminaBlossom use?

The LuminaBlossom is built around the Pico left pins 1-20, from the RP2040/RP2350 family.

How big is the LuminaBlossom PCB?

The LuminaBlossom measures 61.5 × 59.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LuminaBlossom?

7 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the LuminaBlossom design files?

From the LunarEchoo56/LuminaBlossom repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LuminaBlossom design in my own project?

Yes, under the terms of its Apache-2.0 license, which LunarEchoo56 chose for the repository.

Can I test firmware for the LuminaBlossom without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
