Rabbit Labs
Rabbit Labs is a hardware-focused engineering studio creating compact, open, and developer-friendly IoT boards.
Their products emphasize hackability, transparency, and practical networking, targeting engineers, makers, and educators.

Rabbit Labs is an independent hardware company focused on building compact, open, and purpose-driven electronics for security researchers, makers, and embedded engineers.

The company is best known for designing specialized ESP32-based boards that go beyond generic development kits, integrating features such as Ethernet connectivity, GPS, and RF-focused tooling into small, hackable form factors.

Rabbit Labs emphasizes:

• Practical, real-world use cases rather than demo-only hardware
• Open and modifiable designs
• Hardware that bridges experimentation and deployment
• Tools that work reliably outside controlled lab environments

Their products are widely used in network research, wireless experimentation, wardriving, IoT prototyping, and educational projects, offering developers a flexible platform to explore both wired and wireless communication technologies.

Since 2022..

🎯 PRODUCT DESCRIPTION

The Rabbit Labs Yapper Board is a small-form-factor ESP32-based IoT development board designed for projects that require both wired Ethernet stability and wireless flexibility.

Unlike typical ESP32 boards that rely only on Wi-Fi, the Yapper Board integrates an Ethernet interface, making it suitable for reliable, low-latency, always-on IoT applications.

Its design targets developers who want:

• deterministic networking
• easy firmware development
• compact hardware
• real-world deployability beyond hobby Wi-Fi projects
• price : $66.95

🧩 COMPONENTS

🔧 Hardware

• ESP32 microcontroller
• Ethernet interface(W5500, for wired LAN connectivity)
• USB for power and programming
• GPIO headers for sensors and peripherals
• Compact PCB form factor suitable for enclosure use

🌐 Networking

• Ethernet (W5500, wired LAN)
• Wi-Fi (ESP32 built-in)
• Bluetooth (ESP32 built-in)

🛠 SYSTEM POSITIONING

The Yapper Board sits between:

• simple ESP32 Wi-Fi dev boards amd full industrial controllers

It offers wired Ethernet reliability while maintaining the ease of Arduino/ESP-IDF development.

This makes it ideal for:

• long-running services
• infrastructure-connected devices
• environments where Wi-Fi is unreliable or restricted

🧠 ENGINEERING – FOCUSED INSIGHTS

✔ Why Ethernet Matters Here

Many ESP32 projects fail in real deployments due to:

• Wi-Fi instability
• access-point dependency
• unpredictable latency

By adding Ethernet, the Yapper Board enables:

• stable TCP/IP communication
• predictable timing
• easier firewall and network management

✔ ESP32 as a Dual-Network Node

With both Ethernet and Wi-Fi available, developers can:

• use Ethernet for core communication
• keep Wi-Fi/BLE for provisioning or diagnostics
• build fallback or hybrid network strategies

✔ Developer-Friendly Design

The board avoids unnecessary abstraction layers and focuses on:

• direct GPIO access
• standard ESP32 toolchains
• open documentation

✔ Firmware Flexibility & Limitations

The board comes pre-flashed with the ESP32 Wardriver firmware, allowing immediate use out of the box. It is also compatible with Air-Tag firmware and GhostESP firmware without additional modification.

However, using Marauder firmware will disable the board’s GPS functionality, unless a custom fork of Marauder is used that explicitly supports GPS integration.
