To maximize the benefits of the WLX896B schematic, follow these best practices:
Near the FPC connector, pins 34-36 are routed to an unpopulated SOIC-8 (U5). The schematic calls it "Reserved for HDC1080" – but our tracing shows it is a standard I2C bus (SDA on Pin 34, SCL on Pin 35). You can solder any I2C sensor (BME280, MPU6050) here. The stock firmware will ignore it, but custom ESPHome or Tasmota builds will auto-detect it. wlx896b schematic exclusive
: Most versions utilize a universal AC input (100–240V) regulated by a switching power supply circuit to provide stable DC rails. Control Unit To maximize the benefits of the WLX896B schematic,
