BOM Risk Analyzer

iot-sensor-node

IoT Sensor Node

A compact IoT edge node combining an STM32 microcontroller with environmental and motion sensors over I²C, plus ESP32-S3 for cloud connectivity. All parts are active and readily available — this BOM demonstrates a clean risk profile with full corpus coverage.

About this BOM

A compact wireless sensor node designed for environmental monitoring. All parts are in active production with strong multi-source availability.

legacy-industrial-controller

Legacy Industrial Controller

A motor-drive controller board originally designed in the mid-2010s. Contains several parts that are now NRND or EOL — including older-generation power MOSFETs and an op-amp whose recommended replacement is the OPA376. Use this BOM to demonstrate supply-chain risk analysis and alternate suggestions.

About this BOM

Control board from a 2018 industrial automation product still in field service. Several key MOSFETs and op-amps have entered NRND or EOL status.

hobbyist-robot-project

Hobbyist Robot Project

A differential-drive robot based on the Raspberry Pi RP2040 with motor drivers, an IMU for balance/orientation, and a ToF sensor for obstacle avoidance. Uses maker-recognizable parts from the corpus. All parts active and in-stock through standard distributors.

About this BOM

Open-source robotics platform built around the RP2040 and nRF52840. Maker-ecosystem parts with broad distributor coverage.

tricky-edge-cases

Deliberately Tricky Edge Cases

A stress-test BOM designed to exercise the system's ambiguity handling: includes a part number used by multiple manufacturers (2N2222A), an underspecified part family reference (STM32F4), a part absent from the corpus entirely (ACME-XR2000), and a part with historically unclear lifecycle status (NE555). Not-found and ambiguous items should be flagged clearly without confabulation.

About this BOM

A synthetic BOM that exercises edge cases: ambiguous part families, multi-source commodities, and one part entirely absent from the corpus.
