About the Sensor node PCB

Sensor node is an open source RP2040/RP2350 PCB design by mohan-bee, published on GitHub. It is a 2-layer board measuring 54 × 50 mm, with 44 components from 28 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the W25Q16JVSSIQ, TPS63001DRCR, USBLC6-2SC6, TMP102AIDRLR and LIS3DHTR. By type, the board carries 14 capacitors, 12 resistors, 6 ICs, 5 connectors, 3 diodes and 2 switches.

It belongs with the power & battery, sensors and rf & radio designs in this gallery.

From the project

A side-by-side tscircuit and KiCad viewer

Original native KiCad design from the GPT-6 (Codex) board-creation task. No tscircuit output was created; its comparison entry is pending.

Active board-creation time is estimated at 35–40 minutes, excluding the interruption. This was inferred from saved file timestamps, not measured with an active-time timer. It excludes the subsequent viewer/PR work. No reliable token count was recorded.

Sensor node: common questions

What microcontroller does the Sensor node use?

The Sensor node is built around the RP2040, from the RP2040/RP2350 family.

How big is the Sensor node PCB?

The Sensor node measures 54 × 50 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Sensor node?

44 components, from 28 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 Sensor node design files?

From the mohan-bee/tscircuit-gpt-benchmark 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 Sensor node design in my own project?

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

Can I test firmware for the Sensor node 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.
