Know before you buy
Yes. Because the board is stackable, you can connect up to 62 of these FeatherWings on a single I2C bus, allowing you to control hundreds of servos or PWM devices from one Feather board.
Yes. While the Feather board handles the logic, you will need to provide an external power supply to the FeatherWing's power terminal to safely drive multiple servos, as they often draw more current than a standard microcontroller can provide.
This board is designed to work with the standard Feather form factor. It uses the I2C interface, so as long as your Feather board has I2C pins (SDA and SCL), it should be compatible.
The output channels support up to 6V. This is ideal for most standard hobby servos, but be sure to check your specific servo's voltage requirements before connecting them.
The board is designed to stack directly on top of your Feather using Feather Stacking Headers. This allows you to plug the FeatherWing into your Feather and still have access to the pins for other connections.
Absolutely. Since it provides 12-bit PWM outputs, it can also be used to dim LEDs, control motor speed via a driver, or manage any other component that relies on a PWM signal.
