Let your robotic dreams come true with the new DC+Stepper Motor HAT 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.

Raspberry Pi and motors are not included. Works with any and all Raspberry Pi computers with 2x20 connection port.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.

In fact, you can even stack multiple Motor HATs, 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 and solder in a stacking header instead of the one we include.

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.

We even had a little space so we added a polarity protection FET on the power pins and a bit of prototyping area. And the HAT is assembled and tested here at Adafruit so all you have to do is solder on the included 2x20 plain header and the terminal blocks.

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 A+, B+, or Pi 2, but can be used with a model A or B if you purchase a 2x13 extra-tall header and solder that instead of the 2x20

Install the easy-to-use Python library, check out the examples and you're ready to go!

Comes with an assembled & tested HAT, terminal blocks, and 2x20 plain header. Some soldering is required to assemble the headers on. Stacking header not included, but we sell them in the shop so if you want to stack HATs, please pick one up at the same time.

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.

Note: The terminal blocks included with your product may be blue or black.

It's 10PM, do you know where your Raspberry Pi is? If you had this GPS HAT, you would! This new HAT from Adafruit adds our celebrated Ultimate GPS on it, so you can add precision time and location to your Raspberry Pi Model Pi 3, Pi Zero, A+, B+, or Pi 2

Here's the low-down on the GPS module:

-165 dBm sensitivity, 10 Hz updates, 66 channels

Only 20mA current draw

Built in Real Time Clock (RTC) - slot in a CR1220 backup battery for 7-years or more of timekeeping even if the Raspberry Pi is off!

PPS output on fix, by default connected to pin #4

Internal patch antenna which works quite well when used outdoors + u.FL connector for external active antenna for when used indoors or in locations without a clear sky view

Fix status LED blinks to let you know when the GPS has determined the current coordinates

We spun up a HAT based on our Ultimate GPS, added a coin-cell holder for RTC usage, break-outs for all the Raspberry Pi's extra pins, and plenty of prototyping area for adding LEDs, sensors, and more.

Please note, this HAT takes over the Raspberry Pi's hardware UART to send/receive data to and from the GPS module. So, if you need to use the RX/TX pins with a console cable, you cannot also use this HAT. Instead, you'll have to use a composite or HDMI monitor and keyboard to log in, or use ssh to connect over the network to your Pi. Read up on our tutorial for more information on how to use this fine HAT

Comes as a fully assembled GPS + PCB and an additional 2x20 GPIO header. Some light soldering is required to attach the 2x20 GPIO header to the HAT but it's fast and easy for anyone with a soldering iron and solder. You can also swap the plain female header we have with a 'stacky' type that lets you plug in a hat or GPIO cable on top or a slim ultra-low-profile header.

To make air-shipping eaiser, this HAT does not come with a 12mm coin battery! A CR1220 will let you use the real-time-clock capability of the GPS HAT, you can pick one up locally or order one from us.

Brand new and better than ever, we've replaced our Adafruit GPS shield kit with this assembled shield that comes with an Ultimate GPS module. This GPS shield works great with either UNO or Leonardo Arduinos and is designed to log data to an SD card. Or you can leave the SD card out and use the GPS for a geocaching project, or maybe a music player that changes tunes depending on where you are in the city. 

-165 dBm sensitivity, 10 Hz updates, 66 channels

Low power module - only 20mA current draw, half of most GPS's

Assembled & tested shield for Arduino Uno/Duemilanove/Diecimila/Leonardo (not for use with Mega/ADK/Due)

MicroSD card slot for datalogging onto a removable card

RTC battery included, for up to 7 years backup

Built-in datalogging to flash

PPS output on fix

Internal patch antenna + u.FL connector for external active antenna

Power, Pin #13 and Fix status LED

Big prototyping area

Each order comes with one assembled and tested shield, a stick of 0.1" male header and a 12mm coin cell. Some light soldering is required to attach the header to the shield in order to plug it into your Arduino. if you want to stack a shield on top, be sure to pick up a set of stacking headers to use instead. MicroSD card not included either, but we do stock them in the shop!If your project is going to be inside an enclosure, you'll love this shield as it has external antenna support. Simply connect an external active GPS antenna via a uFL/SMA cable to the shield and the module will automatically switch over to use the antenna. You can then place the antenna wherever you wish.We think this is the Ultimate GPS shield and we also think you'll agree!
