About the KiExport PCB

KiExport is an open source RP2040/RP2350 PCB design by vishnumaiea, published on GitHub. It is a 2-layer board measuring 51 × 21 mm, with 51 components from 31 distinct parts.

Its main chip is the RP2040-B2, from the RP2040/RP2350 family. Other key parts include the W25Q32JVSSIQ and MIC5219-3.3YM5-TR. By type, the board carries 18 capacitors, 11 resistors, 9 connectors, 4 jumpers, 3 ICs and 3 diodes.

From the project

Tool to export manufacturing files from KiCad PCB projects.

Mitayi Pico is the first development board from CIRCUITSTATE Electronics. It is a small development board based on the RP2040 microcontroller from Raspberry Pi. The board is designed after the official Pico board from Raspberry Pi, but adds a few improvements over it.

The schematic and PCB are designed with KiCad, an open-source EDA tool. All the design files of Mitayi Pico are completely open-source and released under the MIT license.

The KiCad project lives in the vishnumaiea/KiExport repository on GitHub; these links point at the commit this page was built from.

KiExport: common questions

What microcontroller does the KiExport use?

The KiExport is built around the RP2040-B2, from the RP2040/RP2350 family.

How big is the KiExport PCB?

The KiExport measures 51 × 21 mm, has 2 copper layers and is 1 mm thick.

How many components are on the KiExport?

51 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the KiExport design files?

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

Can I use the KiExport design in my own project?

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

Can I test firmware for the KiExport 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.
