SparkFun – Alcohol Gas Sensor – MQ-3 – Gas Sensor Breakout Board
SparkFun: SEN-08880
Description: This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC.
Features:
- 5V DC or AC circuit
- Requires heater voltage
- Operation Temperature: -10 to 70 degrees C
- Heater consumption: less than 750mW
Dimensions:
- 16.8mm diameter
- 9.3 mm height without the pins
SparkFun: BOB-08891
Description: Simple breakout board for the MQ – 3, MQ – 4 and MQ – 6 gas sensors. All you need is VCC at 5V, GND, and a resistor to an ADC, that is it.
Note: This is the PCB only. Sensors listed below.
Dimensions: 16.8mm diameter

Description: A row of headers – break to fit. 40 pins that can be cut to any size. Used with custom PCBs or general custom headers.
Features:
- Pin Style: Square
- Number of Pins: 40
- Pin Spacing: 0.1″ (2.54 mm)
- Pin Length: 11.5 mm

SparkFun – ProtoBoard – Square 2″
SparkFun: PRT-08811
Description: This is a very simple but handy, 2″ square, double sided perf board. Standard 0.1″ spacing with a 4-40 (3mm) holes for mounting. Great for quickly prototyping stackable circuits.

SparkFun – ProtoBoard – Wombat (PTH)
SparkFun: PRT-08619
Description: An empty canvas for electrical enthusiasts! Designed to fit the SFE project enclosures this project board gives you 8x10cm (3.15×3.94″) of building space for through-hole components with 2.54mm (100mil) spaced holes. This is not your normal perf board! This board is much higher quality with plated-through holes and annular rings that will not lift off the PCB under normal soldering conditions.
The marsupial naming convention is what happens when you let Engineers into a Marketing meeting. They looked so happy, we just couldn’t tell them no. Wombat is the board with nothing but PTH prototyping pads.
Dimensions: 8x10cm (3.15×3.94″)

SparkFun – Female Headers
SparkFun: PRT-00115
Description: Single row of 40-holes, female header. Can be cut to size with a pair of wire-cutters. Standard .1″ spacing. We use them extensively in the Olimex development boards. They mate very well with break away male headers.
Please Note: You will probably lose one pin with each cut.
Features:
- Receptacle Style: Square
- Number of Pins: 40
- Pin Spacing: 0.1″ (2.54 mm)
- Receptacle Depth: 6 mm

SparkFun – Standoff – Metal (1″, 4-40)
SparkFun: PRT-10738
Description: Metal long standoffs: 1″ long x ¼” OD. Used to get your proto board up off the table. #4-40 thread. Fits most development boards with available holes. Don’t forget the screws, found below.
Note: Packs of ten.

SparkFun – Spring Terminals – PCB Mount (6-Pin)
SparkFun: PRT-08077
Description: These are small spring terminals. Open the aperature with the small arm, insert the wire, release the arm and the wire is held firmly in place. This is a good quick way to to interface to bare wires. Capable of higher current and more resilient than breadboard or female header type connections.
Terminals with 0.1″ standard spacing. Inserts directly into perf and proto board. Comes in 2, 3, 4, 5, and 6 positions. Rated up to 150V @ 2A. Terminal can accept 26 to 20AWG wire.

SparkFun – Nut – Nylon Locknut (4-40)
SparkFun: PRT-10460
Description: These are standard locknuts with 4-40 thread. For use with 4-40 machine screws. They have a nylon insert that allows them to stay tightly in place.
Note: These come in packs of 10.

SparkFun – Screw – Phillips Head (1/4″, 4-40)
SparkFun: PRT-10453
Description: There are your standard Philips-head 4-40 screws. They are ¼” long and come in packs of ten. This is the screw size we use in most of the holes for our breakout boards. Check below for other associated hardware. 10 packs.

SparkFun – Polymer Lithium Ion Battery – 1000mAh
SparkFun: PRT-00339
Description: These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cell outputs a nominal 3.7V at 1000mAh! Comes terminated with a standard 2-pin JST-PH connector – 2mm spacing between pins. These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium Polymer charger.
Battery includes built-in protection against over voltage, over current, and minimum voltage. Please use caution when using this battery in wearable projects. When using conductive thread, a short in the thread can create sparks and heat. We recommend using coin cell batteries for beginners.
Note: Although these cells are rated for 2C continuous discharge, the wiring and connectors are only rated up to 1A, so be sure to take that into account when determining your power requirements.
Note: Be careful with the JST connectors. They can stick in pretty good and tugging on them can damage the connector.
Dimensions: 50.8 x 33.5 x 5.9 mm
Weight: 22g
Features:
- Excellent long-term self-discharge rates (<8% per month)
- Robust power source under extreme conditions (-25 to 60C)
