Reliable development tool

Using this for motor control experiments. The G4 series handles PWM very well. Highly recommended.

Good value but needs care

Great core board for the price. Pin headers were not included so I had to solder them myself. Otherwise excellent.

Decent but documentation scarce

The board itself is fine, but finding specific pin mapping examples took some time. Good for experienced users.
