✅ Add-ons: LoRa, dual relay, solar charging, UPS battery
The GEIA IoT Hydroponics Automation Board v2 is a powerful and flexible solution for automating hydroponics, aquaponics, and aeroponics systems. Built for DIY growers and professionals alike, it reduces wiring complexity and makes controlling sensors, pumps, solenoids, and fans effortless.
With dual power inputs (9–12V jack and USB 5V), the board can power 12V appliances and also handle 5V and 3.3V sensors. It includes connections for relays with integrated power lines, so you can wire relays directly and supply 12V to appliances such as solenoid valves without needing an extra power supply.
