📊 Key Features Explained
🧪 Advanced Environmental Sensing
The board integrates three Renesas sensors:
✔ HS4001 — ultra-low power, precise temperature & humidity readings.
✔ ZMOD4410AI1V — AI-enabled indoor air quality sensor for TVOC & CO₂ estimations.
✔ ZMOD4510AI1V — monitors NO₂ and O₃ for outdoor or polluted air detection.🔧 Small but Powerful
Form factor: Only ~22.86 × 22.86 mm — extremely compact for integration into space-limited applications.
Onboard MCU: Powered by a Renesas RA2E1 Cortex-M23 microcontroller (48 MHz), with 128 KB flash and 16 KB RAM — although this MCU is part of the sensor board and is not user-programmable.
🔌 Interfaces & Connectivity
Communicates with your host board via ESLOV (I²C) or through header/castellated pins.
Supports UART, SPI, and multiple ADC channels — enabling diverse integration options.
💡 Ultra-Low Power & Always-On
Designed for 24/7 monitoring, the board consumes very little power — perfect for battery-powered IoT air quality stations and long-term deployments.
🧠 Software & Integration
✔ Arduino IDE Support: Works with standard Arduino libraries for environment and sensor data collection.
✔ MicroPython Support: You can also program through MicroPython for quick prototyping.
✔ Tutorials & Examples: Multiple examples are available in Arduino docs and online guides to help you get started.
