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.

Specifications

  • 100mcd
  • 14.2mm (0.56") digit height
  • Color: red (630nm)
  • Common cathode display
  • Maximum power dissipation per segment: 66mW
  • Maximum pulse peak forward current per segment (1/10th duty cycle, 0.1ms pulse width): 100mA
  • Maximum forward current per segment: 20mA
  • Maximum reverse voltage: 5V
  • Maximum reverse current: 20µA
  • Typical forward voltage: 2.1V at 20mA
  • Maximum forward voltage: 2.5V at 20mA
  • Operating temperature range: -30°C - 70°C
  • Typical luminous intensity: 20mcd

Four Way Solid State Relay Module (solid relay 4 red)
Description:

The four-channel relay module contains four 5V relays and the associated switching and isolating components, which makes interfacing with a microcontroller or sensor easy with minimum components and connections.

A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. It serves the same function as an electromechanical relay, but has no moving parts and therefore results in a longer operational lifetime.

Specifications:

5V Omron solid state relays 240V / 2A, output with resistive fuse 240V / 2A.
Dimensions: 57x55x25 (length x width x height)
Input Power: 5VDC
Control signal input voltage: (0-2.5V low state relay ON) (3-5V state high relay OFF)

Features:

Voltage:5V
Quiescent current: 0 mA
Operating current: 12.5mA
Trigger Voltage: 3.3-5V
Trigger current: 2mA

DC : positive power supply (according to the relay voltage supply)
DC-: negative power supply
CH1: relay module signal triggering end (high to trigger active)
CH2: relay module signal triggering end (high to trigger active)
CH3: relay module signal triggering end (high to trigger active)
CH4: relay module signal triggering end (high to trigger active)

Package includes:

1 x Four way Solid State Relay Module

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.
