Budget: 5000 UAH Deadline: 20 days
The amount and deadlines are conditional, you need a technical task.
It is not clear why you need pico, if there is a better significantly cheaper solution on this core.
Even if you need PICO for other reasons) install STM32F0 or even G0 series, in a package
LQFP48 or LQFP64 (it is not clear yet what other peripherals you need) between lasers and PICO will be the right solution.
The price of these microcontrollers starts from 35 UAH. (I will send a link where you can buy in the comments) In Ukraine.
So using other microchips - for example, shift registers doesn't make sense.
As the price and size of the board will be larger.
The time when the microcontroller cost too much has passed)
So provide a more detailed technical task in personal messages.
