Raspberry Pi 5
Quad-core single-board computer — the hub that runs Home Assistant and coordinates your whole grow.
Raspberry Pi Zero 2 W
Tiny quad-core Pi with Wi-Fi — a low-power hub for small grows and camera nodes.
Raspberry Pi Pico 2
Dual-core RP2350 microcontroller — cheap, deterministic control for a single subsystem.
ESP32 Development Board
The classic Wi-Fi/BLE workhorse — the most common brain for grow automation nodes.
ESP32-S3 Development Board
Faster ESP32 with native USB and extra RAM — our default for new automation nodes.
Arduino Uno R4
The beginner-friendly classic, now with more power and an optional LED matrix.
Arduino Nano ESP32
Arduino's tiny ESP32 board — Wi-Fi and the Arduino ecosystem in a breadboard-friendly form.
Breadboards
Solderless 830-point boards for prototyping a circuit before you commit.
Prototype Perfboards
Solderable proto boards to make a breadboard circuit permanent and rugged.
GPIO Expansion Boards
Break out and label Pi/ESP32 pins to screw terminals for tidy, reliable wiring.
Logic Level Converters
Safely bridge 3.3 V and 5 V devices so you don't fry a GPIO.
RTC Modules
Battery-backed real-time clock so schedules survive a reboot or power loss.
OLED Displays
Crisp 0.96" I²C screens to show readings right on the node — no laptop needed.
LCD Displays
Classic 16×2 character LCDs with I²C backpack for simple, readable status panels.
DAC/ADC Modules
Add precise analog in/out to a Pi — read 0–10 V sensors, output control voltages.
