About the Rca rasp PCB

Rca rasp is an open source Raspberry Pi PCB design by Unosoluciones, published on GitHub. It is a 2-layer board measuring 85 × 55 mm, with 7 components from 7 distinct parts.

Its main chip is the RaspberryPi_Pico_2, from the Raspberry Pi family. Other key parts include the KCX_BT_EMITTER. By type, the board carries 2 ICs, 2 connectors and 1 capacitor.

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

From the project

Driver para conectar por bluetooth cualquier dispositivo con salida RCA

Diseño esquemático completo, trazado de PCB de 2 capas y firmware en MicroPython para un Transmisor de Audio Bluetooth de alta calidad controlado por el microcontrolador RP2350 (Raspberry Pi Pico 2).

El proyecto cuenta con entradas de audio analógicas duales (RCA Izquierdo y Derecho), interfaz gráfica LCD 1602A operada en bus paralelo de 4-bits, control de contraste por trimpot 3362P y topología de masa en estrella (Star Grounding) para eliminar cualquier ruido digital en la línea de audio.

Rca rasp: common questions

What microcontroller does the Rca rasp use?

The Rca rasp is built around the RaspberryPi_Pico_2, from the Raspberry Pi family.

How big is the Rca rasp PCB?

The Rca rasp measures 85 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rca rasp?

7 components, from 7 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 Rca rasp design files?

From the Unosoluciones/De-RCA-a-BT 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 Rca rasp design in my own project?

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

Can I test firmware for the Rca rasp without the hardware?

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