# ESPrinkler32 Product Brief

## Product family

ESPrinkler32 is splitting into two related lanes instead of forcing one board to satisfy everyone.

### ESPrinkler32 Maker — rev4.1

**Audience:** DIY ESP32, Home Assistant, ESPHome, local-first automation, garage-maker crowd.

**Positioning:** A hackable local-first ESP32 sprinkler/automation controller for people who want control, expansion, and no cloud subscription dependency.

**Hardware shape:** Hybrid SMD/through-hole board. PCBWay can place the small SMD parts; Chuck/makers hand-solder the chunky field-serviceable parts.

**Value props:**
- Local web UI and API
- Home Assistant friendly
- Weather-brain integration
- OTA firmware updates
- Expansion headers
- LED ring/status interface
- Open hardware/firmware path

**Offer ideas:**
- Board-only
- PCBWay SMD-assembled board
- Partial kit
- Firmware/image bundle
- STL/enclosure files

### ESPrinkler32 EDU — rev4.0

**Audience:** STEM schools, STEM departments, robotics/electronics clubs, makerspaces, community college labs.

**Positioning:** A real ESP32 automation project that teaches soldering, GPIO, I2C, relays, web APIs, scheduling, debugging, and safe low-voltage system thinking.

**Hardware shape:** Old-school through-hole kit. More teachable, more forgiving, easier to inspect and repair.

**Important framing:** Sell it as an ESP32 automation controller with sprinkler-themed real-world context, not as a classroom live-irrigation wiring project.

**Offer ideas:**
- Single student kit
- 10/15/30 pack classroom kit
- Instructor kit
- Pre-flashed ESP32 option
- Replacement parts bag
- LED/demo-load board
- Student worksheet + instructor guide

## First validation channel

Olivia and Mandy attend a STEM school across town. That school is the obvious first feedback lane:

- Ask a STEM teacher what makes a kit classroom-safe and teachable.
- Show the LED ring “lights off” demo.
- Offer a pilot with 5–10 kits and teacher docs.
- Let actual school friction shape the kit before building a store.

## Current recommendation

Do not write a heavy MBA business plan yet.

Do now:
- Product thesis
- Cost model
- Manufacturing checklists
- Curriculum seed
- Mockup/merch concept page
- First-teacher validation path

Wait on:
- Inventory commitments
- Formal projections
- Polished ecommerce
- Large packaging runs

## Working tagline ideas

- Local-first sprinkler control for practical people.
- ESP32 automation that gets its hands dirty.
- Maker board. Classroom kit. Same weird little galaxy.
- Future Liability™, Lab Supervision Required.
