About the LedScreen PCB

LedScreen is an open source RP2040/RP2350 PCB design by Nickdev8, published on GitHub under the MIT license. It is a 2-layer board measuring 87 × 84 mm, with 39 components from 21 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. Other key parts include the 74HCT245. By type, the board carries 8 resistors, 3 capacitors, 1 IC, 1 module and 1 connector.

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

From the project

With this board you can control multiple WS2812 LED lines with XLight sequences. The main idea is that I wanted one board that could handle the panel data, SD card playback, and animation syncing between boards. That i all achieved with this pcb.

The basic idea is: 1. Flash the Pico with the firmware from arduinofirmware/Main/. 2. Put .lsa` animation files in the SD card root. 3. Connect the LED panels and power them from an external regulated 5V PSU. 4. If needed, chain multiple boards together with the sync in/out headers.

LedScreen: common questions

What microcontroller does the LedScreen use?

The LedScreen is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the LedScreen PCB?

The LedScreen measures 87 × 84 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LedScreen?

39 components, from 21 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the LedScreen design files?

From the Nickdev8/LedScreen repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the LedScreen design in my own project?

Yes, under the terms of its MIT license, which Nickdev8 chose for the repository.

Can I test firmware for the LedScreen 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.
