Adafruit DC & Stepper Motor Bonnet for Raspberry Pi
影片（5:16開始~7:15）：https://youtu.be/Vmyj0Kiu2mo
Let your robotic dreams come true with the new DC+Stepper Motor Bonnet from Adafruit. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control. We basically took our super-popular DC+Stepper Motor HAT and squeezed it down and made it fully assembled - plug and play ready to go, no soldering required!
／借助 Adafruit 的新型 DC+步進電機閥蓋，讓您的機器人夢想成真。這個 Raspberry Pi 插件非常適合任何運動項目，因為它可以驅動多達 4 個 DC 或 2 個具有完全 PWM 速度控制的步進電機。我們基本上採用了我們超受歡迎的 DC+步進電機 HAT 並將其擠壓並完全組裝 - 即插即用準備就緒，無需焊接！
Raspberry Pi and motors are not included. Works with any and all Raspberry Pi computers with 2x20 connection port.／Raspberry Pi 和電機不包括在內。適用於任何和所有具有 2x20 連接端口的 Raspberry Pi 計算機。
Since the Raspberry Pi does not have a lot of PWM pins, we use a fully-dedicated PWM driver chip onboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins.／由於 Raspberry Pi 沒有很多 PWM 引腳，我們使用一個 完全專用的板載 PWM 驅動芯片 來控制電機方向和速度。該芯片通過 I2C 處理所有電機和速度控制。驅動多個電機只需要兩個引腳（SDA 和 SCL），由於它是 I2C，您還可以將任何其他 I2C 設備或 HAT 連接到相同的引腳。
In fact, you can even connect multiple Motor Bonnets by using the PHAT Stacker, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase multiple stackers.／事實上，您甚至可以 使用 PHAT Stacker連接多個電機罩，最多 32 個，用於控制多達 64 個步進電機或 128 個直流電機（或兩者的混合） - 請記住購買多個堆垛機。
Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time), a big improvement over L293D drivers and there are built-in flyback diodes as well. A chunky polarity protection FET will protect your precious Pi and Bonnet from accidental mis-wiring of the battery/power port. The Bonnet is fully assembled and tested here at Adafruit so all you have to do is plug it right onto your Raspberry Pi.／ 電機由 TB6612 MOSFET 驅動器控制，具有每通道 1.2A 的電流能力（一次可以吸收高達 3A 的峰值電流約 20ms）， 與 L293D 驅動器相比有了很大的改進，並且還內置了反激二極管。厚實的極性保護 FET 將保護您珍貴的 Pi 和 Bonnet 免受電池/電源端口意外接線錯誤的影響。Bonnet 已在 Adafruit 完全組裝和測試，因此您只需將其直接插入您的 Raspberry Pi 即可。
Lets check out these specs again:
- 4 H-Bridges: TB6612 chipset provides 1.2A per bridge with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
- Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
- Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
- Big terminal block connectors to easily hook up wires (18-26AWG) and power
- Polarity protected 2-pin terminal block and jumper to connect external 5-12VDC power
- Works best with Raspberry Pi model Zero, A+, B+, or Pi 2, Pi 3, etc but can be used with a model A or B if you purchase a 2x13 stacking header to lift the board.
- Install the easy-to-use Python library, check out the examples and you're ready to go!
Comes with an assembled & tested Bonnet, terminal blocks and 2x20 header are already attached and ready to go. Raspberry Pi, motors, and battery pack are not included but we have lots of motors in the shop and all our DC motors, and stepper motors work great. Check out our detailed tutorial for tons of info including schematics, wiring diagrams, python libraries and example walkthroughs. ／ 隨附組裝和測試的閥蓋、接線端子和 2x20 接頭已連接並準備就緒。Raspberry Pi、電機和電池組不包括在內 ，但我們店裡有很多電機，我們所有的直流電機和步進電機都很好用。查看我們的詳細教程，了解大量信息，包括原理圖、接線圖、python 庫和示例演練。
Note: The terminal blocks included with your product may be blue or black.／注意：您的產品隨附的接線端子可能是藍色或黑色。
