Adafruit – Potentiometer Knob – Soft Touch T18 – Red

Adafruit 2046 Mk01

Adafruit 2046 Mk02

Adafruit 2046 Mk03

Adafruit 2046 Mk04

Adafruit 2046 Mk05

Adafruit: 2046

Description

Oh say can you see
By the knob’s early light…

Sorry – we thought that was clever. And while it wasn’t really, this potentiometer knob definitely is. It’s a ‘soft touch’ T18 knob that works great with our Panel Mount 10K, Panel Mount 1K, and Panel Mount 100K potentiometers. The knob is designed to set directly on the potentiometer’s ridges so it’s an easy & secure fit. It has a nice feel, with a rubbery grip, tweaking it is quite fulfilling.

This is the blue version and it has a nice deep color on the inside with a striking blue line on the outside for great visibility with whatever you’re making. We also carry it in white and red if you’re looking for a variety of colors.

Technical Details

  • Diameter of the top: 11mm / 0.4″
  • Diameter of the base: 15mm / 0.6″
  • Weight: 1g
  • Colour: Red

Adafruit – Standard LCD 20×4 + Extras – White on Blue

Adafruit 198 Mk01

Adafruit 198 Mk02

Adafruit 198 Mk03

Adafruit: 198

Description

Standard HD44780 LCDs are useful for creating standalone projects.

  • 20 characters wide, 4 rows
  • White text on blue background
  • Connection port is 0.1″ pitch, single row for easy breadboarding and wiring
  • Single LED backlight with a resistor included, you can power it directly from 5V. If it’s too bright for you, it can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlights
  • Can be fully controlled with only 6 digital lines!
  • Built in character set supports English/Japanese text, see the HD44780 datasheet for the full character set
  • Up to 8 extra characters can be created for custom glyphs or ‘foreign’ language support (like special accents)
  • Comes with necessary contrast potentiometer and strip of header

For more information, check out our detailed step-by-step Arduino+LCD tutorial

We have a generic 20×4 datasheet that has dimensions and pin-locations (the exact model may vary but the pinout, size and protocol information is the same). We also have a HD44780 datasheet with the detailed commands for control.

Adafruit – 20mm Coin Cell Breakout Board (CR2032)

Adafruit 1870 Mk01

Adafruit 1870 Mk02

Adafruit 1870 Mk03

Adafruit 1870 Mk04

Adafruit: 1870

Description

Simple but effective – this breakout board has a CR2032 coin cell battery holder soldered on and 0.1″ pitch breakout pins for easy connecting. Great for powering very low-current projects, or adding a battery backup circuit to a real-time-clock or similar.

Comes with one fully assembled and tested coin cell battery holder and a small stick of 0.1″ header so you can solder it on and plug into a breadboard. Coin cell battery is not included.

Technical Details

Dimensions:

  • 23.5mm x 28mm x 1.6mm / 0.9″ x 1.1″ x 0.06″
  • Mounting hole distance: 18mm x 22mm / 0.7″ x 0.9″
  • Weight: 3g

Adafruit – 3 x AAA Battery Holder with On/Off Switch and 2-Pin JST

Adafruit 727 Mk01

Adafruit 727 Mk02

Adafruit 727 Mk03

Adafruit 727 Mk04

Adafruit 727 Mk05

Adafruit 727 Mk06

Adafruit: 727

Description

This battery holder connects 3 AAA batteries together in series for powering all kinds of projects. We spec’d these out because the box is slim, and 3 AAA’s add up to about 3.3-4.5V, a very similar range to Lithium Ion/polymer (Li-Ion) batteries and have an on-off switch. That makes them ideal for use with 3.3V projects that have a 2-pin JST connector meant for one of our Li-Ion/Poly batteries. (Of course, you can’t recharge them like Li-Ion/Polys, so don’t try to plug this into one of our Li-Ion/Poly charger boards!)

Fits any standard AAA battery. When using rechargeable NiMH the output voltage will range from about 3.7V with charged batteries to 2.7V at the end of life with a nominal voltage of 3.6V. When using alkalines, the output will range from 4.6V with new batteries to 3.3V at the end of life with a nominal voltage of about 4.5V

The polarity matches that of our 2-pin JST cable and Li-Ion/Poly batteries. Uses a genuine JST connector so it wont ‘catch and tear’ in JST connectors.

Technical Details

  • Box Dimensions: 2.5″ x 1.45″ x 0.62″
  • Cable: 6″ long, terminated with a genuine JST-PH 2 pin connector

Adafruit – 4-pin JST SM Plug + Receptacle Cable Set

Adafruit 578 Mk01

Adafruit 578 Mk02

Adafruit 578 Mk03

Adafruit 578 Mk04

Adafruit: 578

Description

These 4-wire cables are 15cm long and come as a set, one side has a JST SM type connector plug on the end. The other side has a matching JST SM type receptacle connector. They are good for whenever you have 4 wires you want to be able to plug and unplug. We like the solid and compact nature of these connectors and the latch that keeps the cable from coming apart easily. For more information, check the JST SM connector datasheet

Our digital addressable LED strip and 12mm pixels also come with JST SM connectors and you can use these cables to connect to the input or output port

These cables can be used to connect to either the INPUT or OUTPUT port of our LPD8806 digital addressable LED strip or the INPUT or OUTPUT port of our WS2801 LED Pixels so that you can easily plug it into your Arduino or similar and also connect another strand to the output, or perhaps apply power to the ‘output’ end.

Each order receives one of each connector.

Technical Details

  • JST SM plug + recetacle connector: JST SM connector datasheet
  • 15 cm long wires
  • 4 wires, 22AWG stranded
