Description
Description
Dettagli Tecnici del Progetto:
-
Componenti principali:
- alloggiamento per NUCLEO-WL55JC1: Scheda di sviluppo con supporto LoRa.
- 16 uscite digitali per controllare due schede relè preassemblate.
- altre uscite analogiche e digitali per sensori di livello, pressione ecc.
- Interfaccia I2C per la comunicazione con un RTC e un display LCD.
- Alimentazioni a 5V dedicate una per la scheda NUCLEO e le periferiche, e una per le schede relè
-
Componenti EMI:
- Ferriti RH3.5x0.8x9P52E con impedenza di 260 Ohm @ 100 MHz e gestione fino a 2A per ridurre interferenze sulle linee di alimentazione.
- Condensatori ceramici da 100 nF e 10 µF per il filtraggio delle alimentazioni e il disaccoppiamento dei componenti sensibili.
-
Layout del PCB:
- Il PCB è un design a 2 layer, con un layer dedicato principalmente ai segnali e l'altro alla gestione dell’alimentazione e del piano di massa.
- Sono state aggiunte resistenze di pull-up da 4.5kΩ sulle linee SDA e SCL dell'I2C.
