Using an adapter
The Spektrum adapter provides regulated 3.3V from unregulated (up to 15V) ESC/BEC power supplied via Servo headers to the board.
Please remember that USB does not provide power to the FlexiPort or MainPort.
FlexiPort MainPort | Spektrum | |
|---|---|---|
| GND | 1 - Black | 2 - Black |
| PWR | +5V to adapter | 1 - Orange (+3.3V) |
| TX | 3 - Blue | - |
| RX | 4 - Orange | 3 - Grey |
Schematic is pretty simple, you can made your adapter with a few components: Like here
Powered from board
You can get the 3.3V the satellite needs from somewhere else on the board, directly from regulator or more easy with a wire soldered to one of SBL pads that provides +3.3V.
