I have a RasPi 3B+ and some female header connectors. On the V1, I can see that the RasPi plugs its GPIO headers directly into the Nyboard. I assume this is how it's powered but I'm not sure.
Thank you, everyone!
I'll take your advice and try again.
By the way, I use this picture as a method of partial pressure. I have a lot of 1kΩ resistors.
yes you need resistors on the 2 wires to the pi, example here: https://tutorials-raspberrypi.com/raspberry-pi-ultrasonic-sensor-hc-sr04/
I can solder a 2x5 socket on NyBoard to plug in a Raspberry Pi 3A+ .
By the way, can anyone advise me on how to provide a 5V power supply for the sensors connected to the Raspberry Pi?
I expected it can provide from for Grove socket or their front pinhole on Nyboard,
but it seems not to work well.
The Pi's 5V and Grove's 5V are generated by independent chips.
Grove's 5V can only supply 500mA.
Pi's 5V can supply 3A and can be acquired from one 5V pin of the 2x5 socket
What sensor would use that large current?
I used a simple ultrasonic sensor to make this connection. Please forgive the poor picture😓
I tried with a Python program and GPIO combination that works fine when using 5V power from the RPi, but no response when taking 5V power from the Nyboard.
Do I need to insert a resistor in the circuit?
Yes, Pi works at 3.3V logic level. The sensor uses 5V. So it may actually damage your Pi's GPIO if you wire them directly.
