Is BME280 Temp Humidity Barometer Compatible with Home Assistant (MicroPython)?
Electrical Specifications
Always confirm pin assignments against the manufacturer datasheet before wiring.
Compatibility Overview
High-precision environmental monitoring pairing using Pico W and Bosch BME280 sensor over MicroPython MQTT API.
Typical I²C Wiring Reference
Standard I²C signal names. This is a bus reference, not a pinout for this specific board — check the silkscreen and datasheet for its actual pin order.
Reference circuit only. A shifter is needed when the host and peripheral run at different logic levels — check both datasheets to confirm whether this applies to your pairing.
