This is the perfect extension for Raspberry Pi's GPIO to breadboard, with clear GPIO labeling. This is the assembled version of the Pi T-Cobbler. It works with the:
- Raspberry Pi Model Zero WH
- Raspberry Pi 3A+
- Raspberry Pi 3B
- Raspberry Pi 3B+
- Raspberry Pi 4B 1GB (Discontinued, but compatible)
- Raspberry Pi 4B 2GB
- Raspberry Pi 4B 4GB
- Raspberry Pi 5
- Any Raspberry Pi board with 40-pin GPIO (2x20 connector) pre-soldered.
The Raspberry Pi has landed on the Maker World like a 40-GPIO pinned, quad-USB ported, credit card sized bomb of DIY joy. And while you can use most of our great Model B accessories by hooking up our downgrade cable, it's probably a good time to upgrade your set up and accessorize using all of the 40 pins. That's why we now carry the Assembled Pi T-Cobbler - Breakout + Cable for Raspberry Pi. This Cobbler is in a fancy T-shape, which is not as compact but is a little easier to read the labels. It breaks out all those tasty power, GPIO, I2C and SPI pins from the 40-pin header onto a solderless breadboard. This set will make "cobbling together" prototypes with the Pi super easy.
Each order comes with a 40 pin ribbon cable and assembled T-Cobbler. You can plug the 40-pin GPIO cable between the Pi computer and the T-Cobbler breakout. The T-Cobbler can plug into any solderless breadboard. The T-Cobbler PCB has all the pins labeled nicely so you can go forth and build circuits without keeping a pin-out printout at your desk. We think this will make it more fun to expand the Pi and build custom circuitry with it.
Note: Fully assembled, no soldering required!

In a motherboard (or any other circuit board), a jumper is a pair of prongs that are electrical contact points set into the board or an adapter card . When you set a jumper, you place a plug on the prongs that completes a contact. In effect, the jumper acts as a switch by closing (or opening) an electrical circuit.

- Type: Shorting Jumper with tail
- Pitch: 2.54mm.
- Number of Pins: 2.
- Contact Material: Copper Alloy.
- Current Rating: 2A.
- Housing Material: Thermoplastic.
- Operating Temperature: -25°C to 105°C.

This module adopts an 8-bit MCU as the main control chip, it can be applied in distance measurement, testing the performance of the HC-SR04 ultrasonic module. Plus, you can use this module in two ways since it supports Serial Port Display and Digital Tube Display.
Specifications
- Integrated STM8S103 High-Performance Microprocessor
- Interfaces:
- Digital Tube Display
- Serial Port Data Output
- Input Voltage: 5V
- LiPo Connector: 2.54mm socket (5V power supply)
- Measuring Distance: 3cm - 400cm
- Plate Size: 25mm x 35mm
- Weight: 7g
How To Use
Measured distance can be displayed via the digital tube or serial port:
- Digital Display: directly connect ultrasonic sensor and provide 5V power supply (using wire jumpers or LiPo battery).
- Serial Port Output: connect the display module pins (VCC, TX, RX, GND) to USB to TTL converter pins (5V, RX, TX, GND) respectively. Select 9600 baud transmission rate and the output format is "D: XXX", where XXX represents the distance in centimeters.
Note: No code is required to use this module! Plug and play, very easy to use for beginners.
Additional Notes
When measuring the distance, the area of the measured object should not be less than 0.5 square meters, and it should be smooth and have strong reflectivity. Failure to do so will affect the test result.
Valid measuring distance: 3-400cm. If it is longer than this range, it will result in incorrect data or shows a 000 screen.

Copper tape can be an interesting addition to your maker toolbox. The tape itself is made of thin pure copper so it's extremely flexible and can take on nearly any shape. You can solder to it, and the tape itself can carry current just like a normal wire. On the back is an electrically conductive adhesive. The adhesive can't carry significant current, but it is very handy for sensing applications where you don't want to solder the copper tape.
We've seen such tape used for EMI shielding, working with EL, making capacitive touch pads, ultra-thin wiring needs, etc.
It comes in a roll 25 meters long, and this tape is 5mm wide and .07mm thick. The tape has conductive adhesive on one side and a protective paper backing over the adhesive.
This is an example of a circuit made of Copper Foil Tape connected to the LED:
- Conductive Copper Tape
- Tape width: 5mm
- Tape Length: 25 meters
- Tape thickness: 0.07mm
- Adhesive on one side

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single-ended inputs. For example, your Raspberry Pi can read voltage from load cell:
To get you started, here is example code for both the Raspberry Pi (in Adafruit Pi Python library), Arduino (in ADS1X15 Arduino library repository) and CircuitPython. Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.
- Breakout board with standard header spacing (2.54mm)
- Uses ADS1115 ADC converter IC
- Up to
16-bitresolution, we can only get 12-bit resolution. - Wide Operating Voltage Range: 2.0V to 5.5V
- Compatible with both 5V system like Arduino
- And 3.3V system like Raspberry Pi
- Low Current Consumption:
- Continuous Mode: Only 150µA
- Single-Shot Mode: Auto Shut-Down
- Programmable Data Rate: 8SPS to 860SPS
- Internal Low-Drift Voltage Reference
- Internal Oscillator
- Internal PGA
- I2C interface, only 4 wires needed to Raspberry Pi or Arduino
- Pin Selectable I2C Addresses
- Four Single-Ended or Two Differential Inputs
- Programmable Comparator
- This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpers

Simple ON and OFF switch. This is a panel-mount SPDT (single pole double throw) toggle switch.
This 3 pins toggle switch is great for any project where you have two options to select between. Maybe you'll be selecting between two voltages? Two audio outputs? Two sensor inputs? It's up to you! It's short, sweet, blue, and to the point! The part is marked at 3A 250VAC and 6A 125VAC but we haven't tested it at such high current/voltages and don't recommend it for more than 2A at 24V.
- SPDT 3 Terminal ON-ON 2 - Position Latching Toggle Switch.
- Each switch is assembled with two hex nuts, a flat and a locking washer.
- Easy installation, fits into any 6mm hole.
- Stated Electrical Spec: 3A 250VAC or 6A 125VAC, but we recommend using it at 2A at 24V
Relays are always good to have especially for electronics projects. The relay itself offers two main benefits:
- Isolation of low voltage system against high voltage system, example 5VDC and 240VAC
- Allow electronics with low voltage to control high power load, for example from Arduino to AC light bulb.
This is not an ordinary Relay breakout. It comes with 1 (single) channel 3.3V activation relay, ready to control 250VAC at 10A. Extra isolation with optocoupler at the front of control and the activation logic for the relay is configurable via a mini jumper. In simple words, the relay can be configured as 3.3V(High) activation or 0V(Low) activation. This is the universal Relay breakout board and we like it.
It comes with three (3) screw terminals for the relay output:
NO (Normally Opened),
NC (Normally Closed),
COM (Common),
and screw terminals for the control signal from a microcontroller such as Arduino or micro:bit. The control signal is optoisolated, protected. It even comes with power and activation indicator LEDs for the relay. Easy to use and suitable for beginners, and of course students too.
Input power and signal:
- DC+ = +3.3VDC
- DC- = GND (Ground or 0V)
- In1 = Control signal, 3.3V as logic High; 0V as logic Low
If you need to control AC or high current, high voltage load, this will be the perfect board.
Note: We notice the DC+ and DC- need to be 3.3V and the In1 (control signal) needs to be 3.3V or Ground to make it works properly.
- 3.3V One (single) channel relay module
- Configurable Activation Logic, High or Low, via mini jumper
- Maximum Current Rating: 10A
- Maximum Voltage Rating: AC 250V
- Can control various appliances with large current and high voltage
- Can be controlled directly by 3.3V microcontrollers such as Arduino, micro:bit.
- Build-in an Opto-Isolator for extra isolation and protection to the controller.
- A power indicator LED, and another relay activation indicator LED
Warning
Exercise proper caution when connecting mains driven equipment or appliances to relay module as lethal current will be present.
