Electrical Characteristics
This section shows the maximum and minimum ratings of the BOT14000 module and its recommended operating conditions. Refer to the table presented below.
QWIIC Interface Wiring Label
All QWIIC cables follow the color scheme and arrangement in the table below:
| Wire Color | Label |
|---|---|
| Black | GND |
| Red | 3.3 V |
| Blue | SDA |
| Yellow | SCL |
Warning
The recommended maximum current on a QWIIC cable is 226 mA.
I2C Troubleshooting
If experiencing communication issues or erratic behavior with multiple I2C devices connected, try cutting the JP1 jumper to disable pull-up resistors. This permanent modification resolves bus loading conflicts common with 3+ devices on the same I2C bus.
Power Supply (via QWIIC Cable 3V3_S)
| Parameter | Min | Typ | Max | Unit | Conditions |
