About the Riptide PCB

Riptide is an open source RP2040/RP2350 PCB design by SharKingStudios, published on GitHub under the MIT license. It is a 2-layer board measuring 330 × 123 mm, with 250 components from 15 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. Other key parts include the PCA9555D. By type, the board carries 85 switches, 85 diodes, 61 LEDs, 2 ICs, 2 resistors and 1 module.

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

From the project

An Infinitely Expandable Keyboard built during Hackclub Highway!

Each module slot has a 5V, EN, GND, SDA, and SCL lines. After a module is plugged in and ready to work it will pull its EN line high to 3.3V, letting the Pico know there is something there in that expansion slot!

Riptide: common questions

What microcontroller does the Riptide use?

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

How big is the Riptide PCB?

The Riptide measures 330 × 123 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Riptide?

250 components, from 15 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 Riptide design files?

From the SharKingStudios/Riptide 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 Riptide design in my own project?

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

Can I test firmware for the Riptide 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.
