Adafruit – Perma-Proto Quarter-sized Breadboard PCB
Adafruit: 1608
Description
Customers have asked us to carry basic perf-board, but we never liked the look of most basic perf: its always crummy quality, with pads that flake off and no labeling. Then we thought about how people actually prototype – usually starting with a solderless breadboard and then transferring the parts to a more permanent PCB. That’s when we realized what people would really like is a proto board that makes it easy!
This proto-board is the PCB you always wish you had, but never realized it! We took the basic layout of a quarter-sized breadboard (basically, a ‘tiny’ breadboard plus power rails) and turned that into a beautiful PCB. The top side has a white silkscreen, and the same markings you’re familiar with, to make transferring components easy. The bottom has the 5-hole pad design that matches a classic breadboard, with 4 power bus lines on the sides, and no mask so you can easily cut traces when necessary. We used 1.2mm diameter drill holes so even parts with big leads will fit. All holes are thru-plated for strength – these wont peel off with rework. The finish is a gold plate – you won’t get oxidation like with bare copper perf! There are also two mounting holes so you can attach the PCB to your project box.
Once you use a Perma-Proto board, you’ll never go back!

Adafruit – Lithium Ion Battery – 3.7v 2000mAh
Adafruit: 2011
Description
Lithium ion polymer (also known as ‘lipo’ or ‘lipoly’) batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2000mAh. If you need a larger (or smaller!) battery, we have a full range of LiPoly batteries
The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly.
The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 3.0V. It will also protect against output shorts. However, even with this protection it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 2A or less (500mA is best). We suggest our Micro Lipo charger, which has a 100mA default rate. You can also set the Micro Lipo to 500mA rate for a faster charge.
Like most lipos, the batteries we sell do not have thermistors built in. This is why we suggest charging at 1 C or even less – 100 to 500mA is a good rate, and available from any USB port if using a USB-powered charger.
Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, do not abuse these batteries, do not short, bend, crush or puncture. As with all Lithium ion polymer batteries and with any power source – they should be used by experts who are comfortable working with power supplies.

Adafruit – Potentiometer Knob – Soft Touch T18 – Blue
Adafruit: 2048
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: Blue

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

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

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