MODI (ESP32 v04)
modulo wireless ESP32-WROOM-1-S3
⚠ WarningMODI runs from a SELV limited power source: nominal voltage 12/24V DC, permitted range 11V - 25V DC. Outside that range it must not be powered. The device is sensitive to water and moisture: keep it away from fire, water, damp and hot environments. Do not disassemble it: any modification voids the warranty and the authorisation to use it.
