The assembly steps:
Step 1: Welding circuit
Soldering part is simpler, welding sequence according to the principle of component level from low to high, the first welding eight resistance, is important to use multimeter to confirm resistance is correct, D4, D5 R13 R14 can temporarily not welding, integrated circuit chips can temporarily not inserted
Step 2: Mechanical assembly
The red line is connected to the 3V positive power supply, the yellow line grounding, excess wire can be used for motor wire.
Step 3: The installation of a photoelectric circuit
Photosensitive resistance and light-emitting diodes (note polarity) is reverse-mounted on the PCB, and the ground distance is about 5 mm, both photosensitive resistance and light-emitting diodes are 5 mm distance. Finally, you can power test.
Step 4: Vehicle debugging
The right direction is along the universal wheel direction, if you press and hold the left photoresistor, the wheels on the right side of the car should be rotated. Press and hold the right photoresistor, the wheels on the left side of the car should be rotated, if the car driving back, can also exchange the wiring of two motors, if the one side normal and the other side back up, as long as you can swap wiring of back side.
Note: We don't supply any manuals please note this before you buy it.

Fire four solenoids, spin two DC motors or step one bi-polar or uni-polar stepper with 1.2A per channel (3A peak) using the TB6612.
We really like these dual H-bridges, so if you want to control motors without a shield or HAT these are easy to include on any solderless breadboard or perma-proto.
We solder on TB6612 onto a breakout board for you here, with a polarity protection FET on the motor voltage input and a pullup on the "standby" enable pin. Each breakout chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. Just make sure they're good for 1.2 Amp or less of current, since that's the limit of this chip. They do handle a peak of 3A but that's just for a short amount of time. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver!
There's two digital inputs per H-bridge (one for each half of the bridge) as well as a PWM input per driver so you can control motor speed. Runs at 2.7V-5V logic. The motor voltage is separate from the logic voltage. Good for motor voltages from 4.5V up to 13.5V! This wont work well for 3V motors.
Comes as one assembled and tested breakout plus a small strip of header. You'll need to do some light soldering to attach the header onto the breakout PCB. Arduino, motors, and power supply not included. Check out the handy tutorial on assembly and wiring!

The Explorer HAT and Explorer HAT Pro are the perfect prototyping side-kicks for your Raspberry Pi!
We've added a heap of useful input and output options that will take your projects to the next level. Great for driving motors, using analog sensors, interfacing with 5V systems, and touch (even fruit based!) interfaces.
It's compatible with Raspberry Pi 2, Pi 3, B+, and A+ and comes fully assembled.
Features:
- Four buffered 5V tolerant inputs
- Four powered 5V outputs (up to 500mA!)
- Four capacitive touch pads
- Four capacitive crocodile clip pads
- Four coloured LEDs
- PRO ONLY Four analog inputs
- PRO ONLY Two H-bridge motor drivers
- PRO ONLY A heap of useful (unprotected) 3v3 goodies from the GPIO
- A mini breadboard on top!
5V tolerant inputs - Hook up your Pi to accept input from 5V systems (like Arduino Uno/Leonardo or 5V Trinkets). We've used a 5-channel buffer that will accept anything from 2V-5V as logic high.
5V powered ouputs - The onboard darlington array can supply up to 500mA per channel (but you'll be limited to driving around 1A total from the board). Ideal for stepper motors, solenoids, and relays.
Eight capacitive inputs - Four along the front edge for touch input (labelled 1, 2, 3, 4) and four up the side for attaching crocodile clips to objects (such as fruit, or tin foil) for experimentation!
Four coloured LEDs - Independently controllable LEDs (red, green, blue, and yellow) that make great status indicators.
Four analog inputs (pro only) - A tidy way to integrate analog signals into your project.
Two H-Bridge motor drivers (pro only) - Drive two 5V motors bidirectionally with up to 200mA per channel. Ideal with our micro-metal gear-motors to create the perfect little buggy! You can even soft-PWM for full speed control.

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.
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 and 3A peak current capability, 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 (3A peak) 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+, Pi 2 B or Pi 3 B.
- 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.
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 Adafruit's detailed tutorial for tons of info including schematics, wiring diagrams, python libraries and example walkthroughs.
The ProtoShield is a prototype expansion board with 2 LEDs and 2 buttons, which can be used directly with more convenience. All the pins and power have been lead out. It is very suitable for building prototype circuits with Arduino.
Features:
ProtoShield for Arduino Duemilanove
To build prototype circuits
Directly soldering components on board
Connecting through the mini breadboard
Package includes:
1x Arduino compatible 328 protoshield prototype expansion board
Control 16 Servos with perfect timing!
This HAT can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running.
For use with Raspberry Pi Model A+ or B+, can be used with the Model A or B if you use a tall 2x13 header instead of the included 2x20.
- drive up to 16 servos or PWM outputs over I2C with only 2 pins.
- The on-board PWM controller will drive all 16 channels simultaneously with no additional Raspberry Pi processing overhead.
- stack up to 62 HATs to control up to 992 servos - all with the same 2 pins!
Best of all, Adafruit even have a Python library you can use, so you'll be up and running instantly, to make your robotic creation com to life. The Adafruit PWM/Servo HAT is the perfect solution for any project that requires a lot of servos or PWM outputs! Check out Adafruits detailed tutorial for lots more information including diagrams, schematics, installation instructions and more
Each order contains
- a Servo HAT
- a 2-pin terminal block
- four 3x4 headers
- a 2x20 socket header
You'll need to do some light through-hole soldering to attach the headers onto the HAT circuit board. If you would like to stack multiple HATs onto one Pi, you can also pick up a 2x20 stacking header and a set of right-angle 3x4 headers that should be soldered on instead.
Please note! This kit does not come with Raspberry Pi, servos, or required 5V power supply.
