Is my schematic correct?

[FrankS]

I have designed a simple circuit with buttons and leds to be used with a raspberry Pico board.
Can someone advice me if this is correct so that I can order a PCB?
Thank you

well it would help if you showed us the circuit

Thanks for replying.I thought I will ask first..
Here it is on my Gdrive:

Requires login - impractical. Please upload here as image. File size <300 kB should work well.

It is more conventional ( and less troublesome) to add pull-up resistors in software and to run switches to ground.
Naturally alter code to suit.

• Power supply to the chip is missing.
• Bypass capacitor on the chip's power pins is missing.
• Buttons lack a pull-down to draw the input to GND when not pressed - unless you can use internal pull-down resistors at the GPIO pins.

Thank you all for your suggestions.
I should clarify that I do not propose to use the RPI2040 chip but the board like in the pic below

Hello,

Without the code, we can not tell if the right connections are used.
In the code the inputs and outputs must be declared.
Also what should happen with the leds and switches is in the code.

Pull-up or Pull-down resistors for the buttons are missing anyway. You can use internal pull-ups or pull-downs on the processor, but you need to declare the use of these in software, see here (with the button connected to 3V3, pull-down is what you will need).
Also you may want to or need to debounce the buttons. This example is for the raspberry Pi 4 but the principle is the same for the pico.
