The Pi-Stop is a low cost hardware module designed to allow Raspberry Pi users to take their first steps into interfacing with the real world.

Designed with the learning in mind, everyone will recognise and identify its familiar elements encouraging their use along-side their own projects.

Move past the Stop light

The Pi-Stop is designed to remove many of the common hurdles people are faced with when getting started using hardware with the Raspberry Pi. Often it is difficult to know what components to use and how to connect them, the Pi-Stop makes it simple by plugging directly onto pre-set positions on the Raspberry GPIO connector.

By plugging the Pi-Stop directly on to the Raspberry Pi GPIO header, no extra cables or wires are needed. Unlike many other add-on boards, they do not block unused GPIO pins, keeping them open for other uses. The Pi-Stop can be fitted in 4 standard locations, allowing up to four Pi-Stops to be controlled independently or combined with other hardware.

Prepare to go!

The Pi-Stop provides a simple stepping stone, between pure screen based programming and using physical hardware to interact with the real world. Components like the Pi-Stop will provide a flexible and non-restrictive way to build understanding through experimenting.

Since it is only a step away from a bag of components, it also allows the programming of hardware to be introduced, and the electronics involved can be introduced separately, if desired. Allowing the pupils to discover they can control real things, and then again to discover they can also build their own circuits and control them in exactly the same way.

Often, people are faced with a magic board which they plug in and tell it to do stuff, however it isn't always clear to them why or how it does it. By providing something which they can remove and replace with something (apparently) completely different (- wires, breadboards and LEDs) they will be able to understand the link.

By keeping the hardware very simple, it allows better understanding of what is happening, and allows space to come up with your own projects and apply the concepts with your own ideas in mind.

Ever wanted to use two different operating systems with the same Pi at the flick of a switch? Well now you can!

This 2 in 1 micro SD card switcher is specially designed for the Raspberry Pi, and you can now enjoy the convenience of using two micro SD cards at the same time on the same Pi!

To transfer between your operating systems, insert two micro SD cards into the adaptor (one on top, and one at the bottom, Then ensuring the Pi is switched off and power removed, switch the switch on the adaptor! Next time you boot, it will boot the secondary micro SD card!

This neat little board plugs directly into the Raspberry Pi GPIO header and provides 2 or 4 connectors for small stepper motors

• Fully Assembled - No Soldering Required
• Raspberry Pi Zero Form Factor - works with all versions of Raspberry Pi with 40pin GPIO connector
• Stepper motors and Raspberry Pi not included

Various Power Options:

1. Powered from the Raspberry Pi 5V
2. From the 2-pin Terminal (whatever voltage is required for the motors)
3. Micro-USB - 5V only

Pinout is simple:

• Physical pins 11, 12, 13, 15 for Motor A (GPIO 17, 18, 27, 22)
• Physical pins 16, 18, 22, 7 for Motor B (GPIO 23, 24, 25, 04)
• Physical pins 33, 32, 31, 29 for Motor C (GPIO 13,12,6,5)
• Physical Pins 38, 37, 36, 35 for Motor D (GPIO 20,26,16,19)

Each pin has an associated white LED so you can see the stepper signals going through

Power Supply Alternatives

• Jumper VCC-VSTP (default). Power from the motors is taken from the Raspberry Pi 5V line
  • Micro-USB into Raspberry Pi. 5V for the Pi and the stepper motors goes through a poly-fuse which can trip if 2 motors are used simultaneously
  • Micro-USB into the PiStep board. 5V for both the Pi and the stepper motors is provided directly from the 5V USB input so no problems with 2 motors at once
• Jumper VSTP-VIN. Power for the motors is provided from the 2-pin screw terminal, so can be any voltage that the steppers can handle. Ensure you use the correct polarity! We recommend to keep it below 12V. You will find that the stepper motors can go up to 9V and will be able to step faster, the higher the voltage that is applied, but there will be some deterioration of the life of the stepper motor at a higher voltage.

Python Programming

Please see the excellent example here for some pointers. You will need to change the pin numbers as above and also change the speed so it steps at a visible rate. You may also want to remove the print statements to speed it up. The lines in Red below are changed from the original to operate Motor A.

# Use BCM GPIO references
# instead of physical pin numbers
GPIO.setmode(GPIO.BCM)

# Define GPIO signals to use
# Pins 18,22,24,26
# GPIO24,GPIO25,GPIO8,GPIO7
StepPins = [17,18,27,22]

# Set all pins as output
for pin in StepPins:
  print "Setup pins"
  GPIO.setup(pin,GPIO.OUT)
  GPIO.output(pin, False)

# Define some settings
StepCounter = 0
WaitTime = 0.01

ScratchGPIO Programming

These pins are identical to those required by ScratchGPIO and therefore can easily be driven using simple Scratch commands:

Set motor type for Scratch to be Stepper motor

Set the position of the stepper motor A

Set the speed of the stepper motor A

Make your Raspberry Pi seriously cool with Fan SHIM! This 30mm no-solder, controllable CPU fan with RGB LED and tactile switch will give your Raspberry Pi significantly better thermal performance.

Fan SHIM uses a friction-fit header, so it just slips onto your Pi's pins and it's ready to go, no soldering required! Note that, due to the height of the fan, if you want to use HATs or pHATs with Fan SHIM, then you'll need to use a booster header.

The fan can be controlled in software, so you can do crafty things like toggle it on when the CPU reaches a certain temperature. Use the LED as a handy visual indicator to show fan status, CPU load/temperature, whatever! The tactile switch can also be programmed, so you can use it to toggle the fan on or off, or to switch between temperature-triggered or manual mode.

Oh, and it's compatible with our new Pibow Coupé 4 case for Raspberry Pi 4!

Features

• 30mm 5V DC fan
• 4,200 RPM
• 0.05 m³/min air flow
• 18.6 dB acoustic noise
• Friction-fit header
• No soldering required
• RGB LED (APA102)
• Tactile switch
• Basic assembly required
• Compatible with Raspberry Pi 4 (and 3 B , 3 A )
• Python library and daemon

Kit contains

• Fan SHIM PCB
• 30mm 5V DC fan with JST connector
• M2.5 nuts and bolts

Assembly

Assembly is really easy, and will take less than two minutes.

1. With the component side of the PCB facing upwards, push the two M2.5 bolts through the holes from below, then screw on the first pair of nuts to secure them and act as spacers.
2. Push the fan's mounting holes down onto the bolts, with the cable side of the fan downwards (as pictured) and the text on the fan upwards. Attach with another two nuts.
3. Push the fan's JST connector into the socket on Fan SHIM.

Software

Our Python library lets you control the fan (on/off), RGB LED, and switch. There's a handful of examples to show you how to use each feature, and a script to install a daemon (a service that runs in the background) that runs the fan in automatic mode, triggering it on or off when the CPU reaches a threshold temperature, with a manual override via the tactile switch.

Notes

• When mounting or detaching the fan, or assembled Fan SHIM, do not push on the fan itself, as it is liable to break.
• Not heatsink-compatible!
• Dimensions: 45x39x11mm

Please Note: Raspberry Pi is not included. Picture is for illustration purpose only
Description:

Meet this super ICE Tower CPU Cooling Fan for Raspberry Pi! Tower structure, 5mm copper tube, multi-layer heat sinks, 7 blades powerful fan, all the above combinations make this super radiator for Raspberry Pi. In the case of overclocking, it can reduce the temperature of the Raspberry Pi from 80℃ to 48℃. What amazing! Best of all, this cooling fan supports the new Raspberry Pi 4 Model B. In our actual use, we found that Raspberry Pi 4 has a large amount of heat. with the help of this super fan, the powerful performance of the Raspberry Pi 4 will be fully released.

Please Note:
In the heat dissipation test mentioned above, the temperature was lowered from 80 ° C to 40 ° C. The test conditions are as follows: 1-Room temperature 25 ° C  / 2- Apply silicone grease directly to the heat sink and processor chip  / 3- Raspberry Pi 4 processor

If you use the thermal conductive tape included, you can reduce the temperature from 80 ° C to 48 ° C under the same conditions. It can be seen that the use of silicone grease is better. If you want to achieve the best heat dissipation, we recommend that you purchase silicone grease.
