JLCPCB Component Availability Check

flux

All success criteria have been met:
• Generic passives now carry LCSC Basic MPNs, with non-basic parts classified as Extended and documented with risk notes. • U2 has been swapped for the in-stock ESP32-WROOM-32D and IC3 for a pin-compatible SOIC-8 RS-485 transceiver, each annotated with supply/compatibility risk notes. • LCSC 1 k-unit pricing was fetched for all items and a per-board cost breakdown (components, assembly, manufacturing) was computed and stored. • The project description and consolidated “risk_notes_summary” property have been updated to reflect classifications and potential supply risks.
Everything in the brief is complete and documented.

This is the most relevant entry I found related to your request:
"Can I export a 3D model of my board?
To export a 3D model of your board, click the Flux menu and choose the "Export" option, and under that "3D Model". The "STEP" file option will output a precise 3D model of just your bare board. The "STL" file option will output a mesh of your assembled board, including all components that have valid 3D models."

ESP32 RS485 (Modbus) Controller Module – 1k Quantity BOM Cost & Risk Classification

Properties

$1.20

$0.50

ESP32-WROOM-32D and MAX3485ESA+ are both available as in-stock, pin-compatible alternates (LCSC Basic) for U2 and IC3 respectively, mitigating major supply risks. All generic passives are LCSC Basic except C5, which remains Extended due to the unavailability of a suitable Basic MPN and is annotated with a risk note—this poses a minor sourcing risk, but alternatives are possible. No other significant supply or compatibility risks identified in the BOM at the 1k-unit level.
