“The Pico Pi is a nice small microcontroller and very functional after header pins are soldered on. You have to use the Thonny program with MicroPython, which comes with Raspberry pi OS or can be downloaded for Windows or Mac.”
“Raspberry Pi Pico was delivered by Pimoroni in a cut tape. The another one I bought from ThePiHut came in an antistatic resealable bag.
Blink test shows that Pico works.
As a first project I am going to replace Arduino Nano with Pico in my Si5351-based VFO that is used in a MW/SW superhet receiver.”
