- Daisy One of a kind embedded platform for creating music and sound with an open source audio development board with no soldering.
- Daisy consists of on-board micro USB and 32 GPIO pins for connection possibility with a wide range of devices like a MIDI controller or a sample player. It also features audio codec in-built.
- Daisy can be used for STEM education as it can help understand concepts like sounds, signals and their behavior with time.
The future of technology lies in embedded and miniature systems which are capable of performing functions at par with large sized systems. Daisy features all functions that are required to create your own music, high quality audio and tunes just using your hardware devices. It does not require any kind of soldering but is based on plug and play.
Daisy can help generate ambient audio, sonify data from sensors and even make an esoteric effects pedal, all within this same platform. It is compact single chip which promises high fidelity audio, low latency in audio and is very affordable and easy to use on a day to day basis.
Enwrapped with such impactful features and an affordable price tag, Daisy makes the case for innovation at low cost to be used as a daily driver.
Problem solving by this product
Daisy is one of the first product in the market that enables the user to create a powerful electronic instruments and sound processors. It is an open source initiative and one of its kind audio development board.
From making a generative synthesizer coded in C++ with note triggers to becoming a suitable platform or tool for teaching STEM education, Daisy does it all. This DIY (Do It Yourself) board is multifaceted with a set of unique features which enable multiple functionalities without any need for soldering of components.
The on-board audio codec makes for low latency and high quality.
The embedded music platform, Daisy has an enriched set of features which are described in detail as follows:
1. Audio Input: It contains 2 channels of line level audio I/O on board. This is made possible due to AKM (stereo audio codec) up to 24 bit and 192 kHz. Use of other digital protocols like TDM, I2S, S/PDIF is possible which can be used using the pin headers. Daisy also supports USB MIDI In and Out through the micro USB port.
2. Memory: Daisy is powered by STM32 ARM Cortex-M7 that runs at 480 MHz and features an internal 32-bit floating point processing power. This chip is optimized for DSP instructions. SDRAM of 64 MB and 8 MB of flash memory make possible, the smooth running of Daisy with a 10-minute audio buffer.
3. Connectivity: Daisy is equipped with full-fledged OTG support and a built-in micro USB port along with available pins for a second port. Hence, you can easily build it into an audio interface, a MIDI controller or a sample player. The ports have an extended usage where in it can be doubled up to power, program or debug the Daisy. It also contains, in addition to the micro USB port, 32 GPIO pins which can be configured into various functions like analog converter, SD card interface etc.
4. Audio Quality: The bare metal audio drivers allow for latency of 1ms or less. Also, the 192 kHz audio hardware built in ensures high-fidelity audio.
5. Software/Programming: Daisy supports a number of programming language including Arduino, Python, FAUST etc. It supports various libraries and APIs like libDaisy written in C++ providing access to hardware peripherals and DaisySP in C++ tailored for embedded audio application. All drivers and APIs are licensed under MIT public license and are open source.
Apart from support for various programming language, Daisy also consists of example programs for each evaluation program. Related schematics and technical documents will soon be made available under open source licenses.
6. Education through Daisy: It helps promote STEM education wherein generating and processing audio signals (Math), using programming to translate the concept of sound (Computers), verifying signal integrity and voltage level through Oscilloscope (Science) etc. are some of the examples of Daisy’s use in STEM education.
7. Additional Devices: There are set of Daisy powered Devices like the Daisy Pod (USB powered breakout board for Daisy), Daisy Petal (helps create own effects programs), Daisy Patch (sound designing module), Daisy Field (handy small form synth). These devices, the name suggest have varied functionality.
- Dimension: 23 mm depth
- Power Consumption: 100 mA (this is code dependent
- There are different versions of Daisy:
- v1- ARM processor with M4 processor
- v2 – M7 processor with 32 MB RAM
- v3 – Introduction of 40 pin connector, credit card form factor
- v4 – Introduction of on-board peripherals like SD card, USB etc.
Plan for launch
The first version was launched in the year 2017. The version 4 with even smaller form factor has been listed on Kickstarter for a crowdfunding campaign in 2019.
Currently, it has raised $ 152,204 from 1280 backers. Funding period was up till march 26, 2020.
Each product is assembled in Southern California with each step documented.
It is priced at $ 29 with estimated delivery starting from the month of April 2020.

Daisy by Electrosmith, a company made up by the collective effort of musicians and makers was launched in the year 2017 when it came out Daisy v1. They have been awarded various technology innovation awards for their undaunting efforts in developing DIY music electronics. They specialize in breakout boards, electronic components and modular synthesizers. Their motto is “Helping people build their own audio devices and feeling magic of discovery along the way”.
They believe in long lasting design idea made possible with use of BGA chip, environment friendly factories with each PCB being 100% RoHS compliant and sustainable distribution through use of single ESD bag to protect Daisy.
