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

Adafruit 727 Mk02

Adafruit 727 Mk03

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

SparkFun – DC Barrel Jack Adapter – Male

SparkFun PRT-10287 Mk01

SparkFun PRT-10287 Mk02

SparkFun PRT-10287 Mk03

SparkFun PRT-10287 Mk04

SparkFun: PRT-10287

Description: This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5×2.1mm, center-positive male barrel jack. If you need to connect bare wires to a barrel jack on an Arduino or a development board, this might be the simple solution.

SparkFun – 5-Way Tactile Switch Breakout

SparkFun BOB-11187 Mk01

SparkFun BOB-11187 Mk02

SparkFun BOB-11187 Mk03

SparkFun BOB-11187 Mk04

SparkFun: BOB-11187

Description: Sometimes you need a very small directional input device (world’s smallest game controller, anyone?) This 5-way tactile switch (up, down, left, right, and center click) allows for joystick-like control in a very small package. This breadboard-friendly board breaks out all the switch signals, and includes pullup resistors configured so that the outputs read low when pressed, and high otherwise. (If you wish, you can reverse the power leads for pull-down operation.)

SparkFun – Adapter Board – ICD/ICD2

SparkFun BOB-00193 Mk01

SparkFun BOB-00193 Mk02

SparkFun BOB-00193 Mk03

SparkFun BOB-00193 Mk04

SparkFun BOB-00193 Mk05

SparkFun: BOB-00193

Description: This is a small PCB that adapts the standard Microchip 6-Pin RJ11 connector to the Olimex 6-Pin .1″ Molex Connector. It is used to connect the original Microchip ICD or ICD2 to a Olimex Development board or to a bread board. If you own an Olimex ICD or ICD2, you do not need this board.

Note: The ICD RJ11 cable reverses the programming signals. Please take a look at the PCB Layout image for a better understanding of the signal routing. This board will allow you direct access to the programming lines.

Dimensions: 0.65×1.0″
