About the NodePilot PCB

NodePilot is an open source PCB design by tushroy, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 100 × 70 mm, with 40 components from 21 distinct parts.

Other key parts include the PC817 and B0505S-1WR2. By type, the board carries 16 resistors, 11 capacitors, 3 ICs, 3 transistors, 2 transformers and 1 jumper.

It belongs with the audio and rf & radio designs in this gallery.

From the project

CM108-based AllStarLink radio interface with audio isolation, RF protection, and fully open KiCad hardware design. Created by S21TIP.

This project was designed for both personal use and small-scale production, with a focus on audio quality, RF robustness, and hardware protection.

Channel Driver to used with ASL3: Simpleusb

The complete KiCad schematic, PCB, and design files are publicly available under the CC-BY-SA-4.0 license.

Notes: If you are using buck converters to power Raspberry Pi boards, make sure the switching frequency is greater than 1 MHz for clean audio interfacing. Low-cost converters are often a significant source of RFI, although this circuit can eliminate most of it.
