About the RP2350A QFN-60 Minimal Design Example PCB

RP2350A QFN-60 Minimal Design Example is an open source RP2040/RP2350 PCB design by akreager, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 52 × 51 mm, with 39 components from 19 distinct parts.

Its main chip is the RP2350_60QFN, from the RP2040/RP2350 family. Other key parts include the NCP1117-3.3_SOT223 and W25Q128JVS. By type, the board carries 19 capacitors, 9 resistors, 4 connectors, 3 ICs, 2 switches and 1 crystal.

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

From the project

A bench test instrument for the 1991 GM R/V (square body) electronic instrument cluster. Built as part of a drivetrain swap into a 1985 C10 pickup — the cluster is being adapted from a 1991 R10 Suburban to replace the original cable-driven mechanical cluster.

The 1990–1991 full-size GM R/V Suburban, K5 Blazer, and Jimmy were the last of the square body platform and the first to use a fully electronic instrument cluster. The speedometer receives a 2,000 pulse-per-mile DC square wave signal from an external DRAC (Digital Ratio Adapter Controller) module rather than a mechanical cable. This…
