* fix(stm32/russell): define ENABLE_HWSERIAL2 and Serial2 pins The Russell board variant was missed during Initial serialModule cleanup (PR #9465), which began requiring Serial2 to be explicitly defined via ENABLE_HWSERIAL2 and PIN_SERIAL2_TX/RX rather than relying on implicit defaults, causing a build error. Signed-off-by: Andrew Yong <me@ndoo.sg> * feat(stm32/russell): add BME680 support, exclude modules to fit flash The BME680 is hardware footprint compatible with the BME280 already present on the Russell board, so add it as an additional lib dep to enable environment sensing (temperature, humidity, pressure, gas resistance). The STM32 target has very limited flash. Even traceroute alone causes overflow, so the following modules are excluded to stay within budget: - RANGETEST - DETECTIONSENSOR - EXTERNALNOTIFICATION - POWERSTRESS - NEIGHBORINFO - TRACEROUTE - WAYPOINT AIR_QUALITY_SENSOR is also excluded as it requires the BSEC2 library for real IAQ output, which alone overflows flash by ~44KB on this target. The Adafruit BME680 library is used instead for raw sensor readings.
