Honorable mention to the Raspberry Pi Pico. I still reference it whenever I play with my Pico.
Tough choice, there were so many good products this year.
I chose the Raspberry Pi Pico road test not because of the board itself, but because of the involvement of several road testers who did an excellent job of documentation and teaching. They have created some great blogs to get you started and delve into more advanced features of the Raspberry Pi Pico.
In general, the quality of the road tests and the variety of reviews is great thanks to the diversity of road testers from professionals to makers to amateurs. Good job selecting the applicants.
I did not do any road tests this year, so it is a read-only poll for me.
I learnt the most during the very enjoyable reads of the R&S source meter reviews.
I really like the way Raspberry Pi Pico micropython programs servo PWM. Arduino kinda gets jerky using the servo library. I am going to try loading the RPi Pico with a bunch of servos directly to GPIO and see how well it holds while watching on a scope. I had a USB scope on a PWM output dimming an LED while I taught my last RPi Pico class, I was amazed how dead on the PWM was in frequency.
