Modular Design #
The PlantCtrl hardware has been redesigned from a single large PCB into a more flexible, modular system. This allows users to only build or use the components they actually need for their specific setup.
The system now consists of a MainBoard which acts as the controller and several pluggable or connectable modules.
MainBoard (ESP32-C6) #
- Processor: ESP32-C6 (RiscV)
- Connectivity: WiFi, Bluetooth, Zigbee/Thread support
- Form Factor: Compact main board with headers for modules
- Fully Open Source: Designed in KiCad
Available Modules #
- MPPT Charger: Efficient solar charging for batteries.
- Pump Driver: High-current outputs for pumps and valves.
- Sensor Interface: Support for multiple moisture sensors.
- Light Controller: For LED nightlights or growth lights.
Capabilities #
- Moisture Sensors: Supports multiple capacitive or resistive sensors via expansion modules.
- Pumps/Valves: Support for multiple independent watering zones.
- Power:
- Solar powered with MPPT
- Battery powered with optional Battery Management (Fuel Gauge)
- Can also be used with a standard power supply (7-24V)
- Efficient Power: Use of high-efficiency DC-DC converters for 3.3V and peripherals.
