Serial Servo HATs and Raspberry Pi, Arduino expansion boards 3:15 pm October 2, 2023 By Julian Horsey While building robotics projects, the importance of controllers and motors cannot be overstated.

A Raspberry Pi Pico runs the show, using TMC2209 drivers to command a pair of NEMA17 stepper motors to drag a magnet around beneath the sand.

Priced at just $4, the Raspberry Pi Pico is built on RP2040 chip. “This is the first beta release of CircuitPython 6.2.0.

That includes the newest player to the microcontroller game — the Raspberry Pi Pico, which [pete_codes] used to whip up a nice looking OBS stream deck.

Raspberry Pi Pico 2 is faster and backward-compatible, still only $5 The second generation of the popular hobbyist chip just dropped and it has significantly more power than its predecessor.

The Raspberry Pi Pico is both faster and cheaper than the Arduino Nano, but the nano has better resources and community.
