General • Re: Pico with Sensors of 5V

Hi, thanks for replying,

From your message, I am not understand this line -

You will however need to ensure that no 5V from the sensor, neither for sensor input nor output pins, reaches the Pico pins. That might be achieved using resistor dividers or other means.

Could you explain this

I can take the 5V from pico pin 40[BBUS] and connect directly to the sensor's VCC, then it will work?

Here, the sensor's Power Input is connected to the PICO pins right,

I am connecting the ultrasonic sensor to the Pico

Sensor -
Operating Voltage: 3.3~5V
standby Current: ≤5mA
Average Current: ≤8mA

The sensor has 4 pins,

LabelNameDescription
1 VCCPower Input
2 GNDGround
3 RX Processed Value/Real-time Value Output Selection
4 TX UART Output



Is that we can directly connect the sensor to pico like this -
1. 5V VCC to the pico pin 40
2. GND to the pico pin 3
3. RX to the pico pin 2
4. TX to the pico pin 1

is this connection is correct?

please let me know, I am new to this

Thanks
