* SmartPort telemetry can be setup with `SoftwareSerial` feature turned on, SmartPort configured in SoftwareSerial1 and receiver connected to UART2 TX pad
* Sometimes called Omnibus F4 v2 Pro, but also exists v3, v4 & v5 versions with no functional differences
* Switching voltage regulator - solves problem of overheating BEC

The SOFTSERIAL1 is an uni-directional port mapped to UART6-TX pin.
When enabled, the UART6 is still available as hardware port but it's then RX-only port (good for e.g. receiving S.BUS input). TX instead is controlled in software and can be used for transmitting one-way telemetry (e.g. LTM). Please note that UART6-TX line passes programmable inverter on those boards, so it is a pure output-only port. SmartPort/FPort telemetry requires bi-directional communication, so it is not possible on this port without hardware modification (bypassing the inverter).
