SparkFun – SPDT Mini Power Switch
SparkFun: COM-00102
Description: Simple SPDT slide switch. Rated at 30V/200mA. The pins have .1″ spacing – fits great into a breadboard! Use it as a power switch or general control switch.

SparkFun – SPDT Slide Switch
SparkFun: COM-09609
Description: This is a simple SPDT slide switch – great for use as an ON/OFF button, or just as a general control switch. The pins are spaced by 0.1″, however they are incredibly thin making breadboard use not recommended. The switch is rated for 0.3A at 50VDC.
This switch is just a bit smaller than our popular SPDT Mini Power Switch, but uses the same pin spacing. Being smaller takes up less PCB space (good!), but it does make it a bit harder to hit and flip easily.

SparkFun – Mini Pushbutton Switch
SparkFun: COM-00097
Description: We use these little buttons on everything! These Miniature Single Pole Single Throw switches have a good click to them and are breadboard friendly. Perfect as a tactile reset switch. These buttons are rated up to 50mA.

SparkFun – Dual/Quad Power Amplifier – STA540
SparkFun: COM-09557
Description: The STA540 from STMicro is a 4-channel, class AB audio amplifier designed for high quality sound applications. The four independent channels makes this amplifier a great choice for a number of projects, with needs ranging from four speakers stereo (F/R) to two-speaker bridge solutions. The chip accepts a voltage supply ranging from 8 to 22VDC and has very high output power capability.
This chip comes in a staggered-lead Multiwatt-15 package. While our breakout board for the L298N isn’t designed for it specifically, it will breakout out all pins of the STA540 to a more standard single row of 0.1″ pitch headers. Also, keep an eye out for some upcoming amplifier products based on this chip!
It works great with the 6400BG Heatsink!
Features:
- High output power capability
- Standby function (CMOS compatible)
- Minimum external components count:
- no bootstrap capacitors
- no Boucherot cells
- internally fixed gain 20 dB
- No audible pop during standby operations
- Diagnostic facilities:
- clip detector
- output to GND short-circuit detector
- output to VS short-circuit detector
- soft short-circuit check at turn-on
- thermal shutdown warning
- Output AC/DC short circuit protection
- Soft short-circuit check at turn-on
- Thermal cutoff/limiter to prevent chip from overheating

SparkFun – Piezo Speaker – PC Mount 12mm 2.048kHz
SparkFun: COM-07950
Description: This is a small 12mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interfaces.
Each speaker is PTH solderable and requires an operating voltage of 3.5-5V with a mean current of 35mA max. These speakers also have a typical sound output of 95 dBA and a coil resistance of 42 ±6.3 ohms. Many people call this a buzzer but it is not. The piezo element requires a square wave (common from most microcontrollers) to produce a tone.

Adafruit – Half-Size Breadboard
Adafruit: 64
Description
This is a cute half size breadboard, good for small projects. It’s 2.2″ x 3.4″ (5.5 cm x 8.5 cm) with a standard double-strip in the middle and two power rails on both sides. You can pull the power rails off easily to make the breadboard as thin as 1.4″ (3.5cm) and stick it onto an Arduino protoshield. You can also cut these in half with a saw to create 2 tiny breadboards, or “snap” these breadboards together either way to make longer and/or wider breadboards.
Technical Details
Dimensions:
- 2.2″ x 3.4″ (5.5 cm x 8.5 cm)
- 9.7mm(0.38in) thick, including sticky foam on the bottom
- Weight: 38.9g (1.27oz)
