Four Digit - Seven Segment Display - Red (display 7 segment red)
Description:

This lovely little (14.2mm) seven segment display provides excellent segment uniformity and is highly visible up to seven meters away. It's ultra bright, and provides great readability even in bright ambient light!

It has four digits and a decimal point on each digit, designed for numeric output, so you can use it to add a clock, timer or counter into your next project.

These displays are multiplexed, common-cathode. What that means it that you can use a 74HC595 or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg decimal) at about ~15mA each, and then connect NPN transistors or a TPIC6B595 to the cathodes to sink the 8*20mA = ~120mA maximum per digit.

This is an ultra bright RED colour.

TB6600 32 Segments 4A 40V 57/86 Stepper Motor Driver (TB6600 stepper driver)
Description:

TB6600 is an easy-to-use professional stepper motor driver, which could control a two-phase stepping motor. It is compatible with Arduino and other microcontrollers that can output a 5V digital pulse signal. TB6600 arduino stepper motor driver has a wide range power input, 9~42VDC power supply. And it is able to output 4A peak current, which is enough for the most of stepper motors.

The stepper driver supports speed and direction control. You can set its micro step and output current with 6 DIP switch. There are 7 kinds of micro steps (1, 2 / A, 2 / B, 4, 8, 16, 32) and 8 kinds of current control (0.5A, 1A, 1.5A, 2A, 2.5A, 2.8A, 3.0A, 3.5A) in all. And all signal terminals adopt high-speed optocoupler isolation, enhancing its anti-high-frequency interference ability.

As a professional device, it is able to drive 57, 42-type two-phase, four-phase, hybrid stepper motor.

Features:

1. 9V-40V DC power supply
2. H-bridge bipolar constant phase flow driver
3. The maximum output current is 4.0A (eight optional)
4. Up to 32 segments of six kinds of sub-modes available
5. Input signal high-speed photoelectric isolation
6. Standard common anode single pulse interface
7. Offline keep function
8. Semi-enclosed chassis can adapt to a more demanding environment
9. Provide energy saving semi-automatic current lock function
10. Built-in thermal protection and over-current protection


Specifications:

Voltage: up to 50V
ON resistance (upper lower) = 0.4 Ω
Forward and reverse rotation control
5 kinds of sub-modes selectable (1/1, 1/2, 1/4, 1/8, 1/16 step)
Output current: IOUT = 5.0A (peak within 100ms)
Rated output: IOUT = 4.5 A
Input pull-down resistor: 100 KΩ
Current output alarm pin: Ialert = 1mA
Monitor output pin (MO): Imo = 1mA
With reset and enable pins
With a standby function.
Breaking the traditional single-supply
Built-in thermal protection (TSD) circuit
Built-in voltage protection (UVLO) circuit
Built-in over current detection (ISD), the circuit


Note:

This driver is the upgraded version TB6600, heightening segment to 32 subdivision, suitable for high segmentation applications.
For step motor: 42, 57, 86 type 2 phase 4 phase (4 / 6 / 8 line)

Four Letter pHAT (four letter phat)
Description:

Use Four Letter pHAT to display... four letter words. Not that sort!

Pi ZERO and case not included!

Four Letter pHAT has four 14-segment displays that you can use to display text, numbers, and a host of other characters. Its LEDs are a beautiful retro green, just like you old digital alarm clock. They're driven by the HT16K33 chip over I2C.

It's perfect as a readout for your projects, displaying temperatures, times, etc. and becomes really useful when combined with some of our other boards like Enviro pHAT or Explorer pHAT to display their sensor values.

Features

  • Four 14-segment displays with green LEDs
  • HT16K33 driver chip
  • Compatible with Raspberry Pi 3, 2, B , A , Zero, Zero W
  • Python library
  • Female header and display pins require soldering

Software

Our handy one-line installer will install the Four Letter pHAT Python library for you. We've included a bunch of examples too, to show off what you can do with Four Letter pHAT; things like a clock, a countdown timer, or CPU activity monitor.

7-Segment for micro:bit (7-Segment for micro:bit )
Description:

The 7-segment for micro:bit is a four digit 7-segment display for micro:bit. You can use it to display numbers, but it can also display letters and other characters, albeit with the limits imposed by the 7 segments of each digit.

Powered directly from micro:bit pins it can be used to send messages to the display using the micro:bit’s Serial blocks.

Please note that this version of the 7-Segment for micro:bit uses a red LED display rather than the green display of earlier versions.

Specifications:

The 7-segment for micro:bit is a four digit 7-segment display for micro:bit.
You can use it to display numbers, but it can also display letters and other characters, albeit with the limits imposed by the 7 segments of each digit.
