Firmware line Version Target

Version clarification. KAACK 4.5.3 is not the same as Betaflight 4.5.3. It is a separate firmware based on an older Betaflight 4.5 line, with its own extra features. The KAACK version number does not mean that all fixes from official Betaflight 4.5.3 are included.

Build optionsCommon racing defaults

Receiver mode: Serial RX via UART + selected protocol. Matching telemetry is included automatically for CRSF/ELRS, FPORT, GHST and JETI. Enable Serial RX on the receiver UART in Ports after flashing. report_cell_voltage is a runtime setting, not a build flag.
