ESP32 RS485 (Modbus) Controller Module
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.
