About the Main board

Main board is an open source RP2040/RP2350 PCB design by antonloof, published on GitHub. It is a 2-layer board measuring 86 × 78.3 mm, with 74 components from 24 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the AP62250. By type, the board carries 26 transistors, 23 resistors, 8 connectors, 8 capacitors, 3 ICs and 2 fuses.

From the project

testing to drive tls3001 leds with a pico

Summary: Manchester encoded data: 1 => 10 0 => 01 Timing is critical, keep constant period! When sleeping put data low!

Sync frame: "1"15+"0001"+"0"11 (111111111111111000100000000000)

Reset frame: "1"*15 + "0100" (1111111111111110100)

Data frame header: "1"*15 + "0010" (1111111111111110010)

Data content: "0"+"x"12 + "0"+"x"12 + "0"+"x"*12 where x is the rgb data to send total 39 bits per led repeat this for all leds in series

Main board: common questions

What microcontroller does the Main board use?

The Main board is built around the Pico, from the RP2040/RP2350 family.

How big is the Main board?

The Main board measures 86 × 78.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main board?

74 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Main board design files?

From the antonloof/eta_game_system repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Main board design in my own project?

The repository has no license, so all rights stay with antonloof. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Main board 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.
