BoardPilotSCT-013 split-core AC current clamp con ESP32
Alimentazione 3.3 V
Bus ANALOG
Misura corrente
Pin e collegamento all’ESP32
| Pin | Ruolo | Pin ESP32 | Note |
|---|---|---|---|
| TIP | Non collegato all’ESP32 | — | 3.5 mm jack. AC output: needs a bias circuit (2 x 10 kΩ + 10 µF) before an ADC pin. -000 also needs a burden resistor |
| SLEEVE | Non collegato all’ESP32 | — | 3.5 mm jack. Goes to the bias midpoint (about 1.65 V), not straight to GND |
Collegamento consigliato per l’ESP32 DevKit a 30 pin, evitando i pin della flash, di sola lettura e di strapping. BoardPilot lo controlla mentre colleghi.
