Objectifs:
- Protéger tous les autres boards du Over/Under Voltage pour le 5V, 12V et 24V
- Seulement le 5v et le 24v sont protégé, car les résistance 5% ont trop d'incertitude.
- Injecteur POE(12V custom pinout) pour les cameras branché en Ethernet
- On/Off possible par le MCU
- Diriger le signal des cameras sur les bonnes pins selon la norme Ethernet
- Agir en tant que POE pour les antennes 24V (vrai POE)
- Controller l'alimentation de 2 circuit d'accessoires 12V
- Par 2 connecteurs Ethernet
- Permettre de pouvoir sortir une des 3 tension (5v, 12v, 24v) par un screw terminal
- Alimente la switch ethernet en dessous
- MCU Connecté sur le CAN BUS
- Sélectionner avec les GPIO les cameras qui doivent recevoir du power
Composants principaux:
- ESP32 DEV KIT V1
- TJA1050 (CAN BUS)
- LTC4365 (Over/Under Voltage protaction)
- DMG4822SSD (DIODE pour la switch du LTC4365)
- DELs
- CLP6C-FKB-CKNPRGJBB7A363 (ERROR DEL)
- Boutons
- Horizontal Amphenol 54602 RJ45
- ASSMANN_A-2014 Ethernet connector
- CRJ036-5-TH_2x4 Ethernet connector
- BTS5200 (4 Channel Mosfet)
Fonctionnement:
- Le PDB reçoit 3 tensions régulé en entrée, du 5V, du 12V et du 24V.
- Le 12V sert principalement pour alimenter les caméras qui sont alimentés avec un POE avec un Pinout spécial. Il sert aussi à alimenter 2 circuit d'accessoires potentiels.
- Le 24V sert à alimenter le/les antennes qui sont sur le Rover.
- Le 5V est passé avec les fils de CanBus pour alimenter et communiquer avec les autres PCB du rover
- Le circuit sécurise les trois tensions contre les sur-tensions et le drops de tensions.
- La sortie vers l'ordinateur principal n'est pas utilisé, l'ordinateur est directement branché dans la switch.
