The SparkFun MicroMod Weather Carrier Board lets you build a custom weather station using any MicroMod-compatible processor. It includes three onboard sensors — a BME280 for temperature, pressure, and humidity; a VEML6075 UV sensor; and an AS3935 lightning detector — along with connectors for external wind, rain, and soil moisture sensors.

Part of the MicroMod ecosystem, this carrier board uses the M.2 connector standard for easy processor swapping. A microSD card slot is included for local data logging.

Key Features

• BME280 Sensor – Barometric pressure, humidity, and temperature (I²C, address 0x77)
• VEML6075 UV Sensor – UVA and UVB light measurement (I²C, address 0x10)
• AS3935 Lightning Detector – Detects lightning activity (SPI)
• 2× RJ11 Connectors – For external wind and rain sensors (compatible with SparkFun Weather Meter Kit)
• 3-Pin Latch Terminal – For external soil moisture sensor
• MicroSD Card Slot – Log weather data locally
• MicroMod M.2 Connector – Swap processors without rewiring

Ideal For

• DIY weather stations and environmental monitoring
