The SparkFun Pi Servo HAT allows your Raspberry Pi to control up to 16 servo motors in a straightforward and uncomplicated manner via an I2C connection. Thanks to its I2C capabilities, this PWM HAT saves the Raspberry Pi’s GPIO, allowing you to use them for other purposes. Additionally, the Pi Servo HAT adds a serial terminal connection, which will allow you to bring up a Raspberry Pi without having to hook it up to a monitor and keyboard.
Power to the SparkFun Pi Servo HAT is supplied by a microUSB connector that can be used to power the servo motors only, or to power the servo motors as well as the Pi that is connected to the HAT. This USB connector can also be used to hook up the Pi via serial port connection to avoid having to use a monitor and keyboard for setting up the Pi. To supply power only to the servo power rail (and not the Pi’s 5V power rail), you just need to remove a small blob of solder on the isolation jumper. Doing this allows you to drive heavier loads coming from multiple or larger servos.
Each of this HAT’s 16 servo motor pin headers has been spaced out the correct distance from the others to make it easier to attach your servo motors. They are pinned out in the proper order for most hobby-type servo motor connectors. The Pi Servo Hat is the same size and form factor as a Raspberry Pi Zero and Zero W, but it can also operate with a regular Raspberry Pi.
Note: This HAT does not include headers to connect to a Raspberry Pi, those will need to be purchased separately. We recommend the 2x20 “tall” headers.

SparkFun Pi Servo HAT允許您的Raspberry Pi通過I 2 C連接以簡單直觀的方式控制多達16台伺服電機。由於其2 C功能，該HAT可以保存Raspberry Pi的GPIO，從而可以將其用於其他目的。此外，Pi Servo HAT還增加了一個串行終端連接，可以讓您打起一個Raspberry Pi，而無需將其連接到顯示器和鍵盤上。
SparkFun Pi的電源伺服HAT由microUSB連接器提供，可用於為伺服電機供電，也可為伺服電機以及連接到HAT的Pi供電。該USB連接器也可用於通過串行端口連接來連接Pi，以避免使用顯示器和鍵盤來設置Pi。為了僅向伺服電源軌（而不是Pi的5V電源軌）供電，您只需要在隔離跳線上移除一小塊焊料即可。這樣做可以驅動來自多個或更大舵機的較重負載。
每個這個HAT的16個伺服電機引腳頭已經與其他伺服電機引腳頭間隔了正確的距離，以便更容易安裝伺服電機。對於大多數愛好型伺服電機連接器，它們都以適當的順序被固定。 Pi Servo Hat與Raspberry Pi Zero和Zero W相同的尺寸和外形，但也可以使用普通的Raspberry Pi進行操作。
注意：此HAT不包括和標題連接到Raspberry Pi，需要單獨購買。我們推薦2x20“高”標題 。
