Solenoid Driver Board (Wi-Fi & Bluetooth)

The Ultimate IoT Valve & Lock Controller

Bring your mechanical hardware onto the network. Whether you are building an automated hydroponics system, a smart-home water shutoff valve, or custom electronic door locks, controlling inductive loads usually means dealing with messy relays, external diodes, and fragile wiring.

The Solenoid Driver Board solves this by pairing the wireless power of an ESP32 with an industrial-grade, safely isolated MOSFET driver on a single, breadboard-friendly PCB. It is everything you need to control 5V–12V actuators securely over Wi-Fi or Bluetooth.

💧 Industrial-Grade Solenoid Control

Driving inductive loads like motors, valves, and solenoids can fry standard microcontrollers. We built this board to handle the heavy lifting safely so you can focus on your project.

• High-Efficiency MOSFET Driver: Delivers robust, reliable switching without the clicking or wear-and-tear of mechanical relays.
• 1A Peak Current & Wide Voltage (5V to 12V): Perfect for standard 12V irrigation valves, pneumatic actuators, and electronic strike locks. (Features an onboard 2-ohm limiting resistor).
• Built-In Flyback Diode: Essential protection is baked right into the hardware. It safely dissipates inductive voltage spikes, ensuring your microcontroller runs flawlessly for years.

🌐 A Connected Brain: Dual-Core ESP32 for IoT

At the core of the board is the Espressif ESP32-WROOM-32E, the gold standard for maker IoT projects.

• Always Connected: Native Wi-Fi (802.11 b/g/n) and Bluetooth (Classic + BLE) allow you to easily integrate your hardware into Home Assistant, ESPHome, or custom web dashboards.
• Plenty of Headroom: Two 32-bit LX6 Xtensa MCUs and 4 MB of flash memory give you more than enough power for complex AI/ML edge computing, low-power sensor networks, and heavy automation scripts.
• Bonus Sensors & Expansion: Includes an integrated 3-axis gyroscope, 3-axis accelerometer, and temperature sensor for environmental and motion monitoring, plus a rich peripheral set (SPI, I2C, I2S, ADC, UART) for adding external modules.

💻 Frictionless Software Integration
