SparkFun Noisy Cricket Stereo Amplifier - 1.5W

You won’t need a series four de-atomizer with our rendition of the Noisy Cricket, just wire it up and crank up your tunes! The Noisy Cricket Stereo Amplifier, uses the LM4853 Boomer® IC which can be configured to output up to 1.5W of power in mono operation (4Ω load) or 300mW per channel in stereo operation (8Ω load). The amplifier comes with a dual-ganged pot with a built-in switch to control power and adjust both left and right channel gain.

The SparkFun Noisy Cricket has been designed as an easy to use board with three connection sections, Power, Input, and Output. The power section features three connections, VCC, VCC OUT, and GND all only requiring a voltage range of 2.4-5.5VDC but with only one connection. Meanwhile, the Input and Output sections both have connections for GND, LEFT IN/OUT, and RIGHT IN/OUT for your audio inputs and outputs. It is important to point out that the Output section of the board does feature an extra pin labeled “MONO,” to use this pin (since the Noisy Cricket operates in Stereo out of the box) and get the full output power from the amplifier you’ll need to configure the Noisy Cricket as a mono amplifier, that way the left and right input channels will be combined to drive a single speaker. To enable mono operation all you will need to do is solder two jumper pads on the back of the board labeled ENABLE MONO OUTPUT and MONO BASS BOOST.

With the SparkFun Noisy Cricket Amplifier, you will be provided with a board that fits into the palm of your hand that requires minimal setup that allows you to utilize both stereophonic and monaural sound!

A hookup guide for the Noisy Cricket Stereo Amplifier - 1.5W.

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.
See all skill levels


Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Customer Comments

  • Some remarks: Love the form factor and price. So happy to see an amp board that includes a volume pot, and it’s even ready to panel mount! No need to mount the board itself since it can be supported by the pot mounting nut. Minor disappointment: One of the nice features of this chip is that it can drive a mono speaker at speaker power, then automatically switch over to driving stereo headphones at headphone power when you plug them in. This breakout doesn’t make this possible without greenwire and careful soldering.
