Power¶
The board regulates everything the sensors need internally — you only supply a single DC input.
Input¶
Power the board from either input (they're interchangeable):
| Input | Connector | Use |
|---|---|---|
| External DC | J1 (2-pin) |
Flight / integration — feed from your vehicle's regulated 5 V |
| USB-C | J2 |
Bench / desktop |
| Parameter | Value |
|---|---|
| Input voltage | 5 V nominal (recommended operating range 5.0–5.5 V) |
| Typical current | well under 500 mA in steady ranging |
| Peak current | brief inrush at power-on (all sensors initializing) — size the supply for ≥ 500 mA |
| Protection | reverse-polarity and over-current protected |
Use a 5 V supply
Feed J1 with a regulated 5 V rail. Do not exceed the recommended range —
the board is designed around a 5 V input, and higher voltages are not
supported on the input net.
What the board provides¶
- All sensor supplies are generated on-board from the 5 V input — you do not provide anything to the sensors directly; they're powered through the 8 sensor connectors.
- The host UART connector (
J7) also exposes a protected +5 V pin for conveniently powering a small USB-UART adapter. Treat it as an output only — do not back-feed power into it.
Powering for flight¶
Take a regulated 5 V feed from the flight-control unit / power module to J1,
and take the data connection off the host UART (J7). See
Bring-up & Setup.
