Is it safe to connect an I2C sensor with a limit of 3.6V to the Onion Omega Power Dock2?
The sensor manual has the following warning below:
The DPS 5000 series sensors employ a 4 wire I2C-bus user electrical interface:
Serial data (SDA)
Serial clock (SCL)
The sensor may be used standalone or as part of a network of compatible I2C-bus devices.
The DPS 5000 is intended for use within networks operated from a single supply at a voltage within the range 2.7 V to 3.6 V. Operation outside these limits is not guaranteed and may damage the sensor.
The sensor interface includes 2 reserved signals. These should be left open circuit as connecting to these signals may result in incorrect sensor operation.
Do I make the following connections between the sensor and the power dock2(?):
Sensor Supply + ===== PowerDock2 3.3V
Sensor Supply - ===== PowerDock2 GND
Sensor SDA ===== PowerDock2 SDA
Sensor SCL ===== PowerDock2 SCL
Does this mean that all I2C connected devices can only be driven by a maximum of 3.3V?
