PÚCA DSP is an open-source, Arduino-compatible ESP32 development board for audio and digital signal processing (DSP) applications with expansive audio-processing features. It provides audio inputs, audio outputs, a low-noise microphone array, an integrated test-speaker option, additional memory, battery-charge management, and ESD protection all on a small, breadboard-friendly PCB.
Synthesizers, Installations, Voice UI, and More
PÚCA DSP can be used for a wide range of DSP applications, including but not limited to those in the fields of music, art, creative technology, and adaptive technology. Music-related examples include digital-music synthesis, mobile recording, Bluetooth speakers, wireless line-level directional microphones, and the design of smart musical instruments. Art-related examples include acoustic sensor networks, sound-art installations, and Internet-radio applications. Examples related to creative and adaptive technology include voice user interface (VUI) design and Web audio for the Internet of Sounds.
Compact, Integrated Design
PÚCA DSP was designed for portability. When used with an external 3.7 V rechargeable battery, it can be deployed almost anywhere or integrated into just about any device, instrument, or installation. Its design emerged from months of experimentation with various ESP32 development boards, DAC breakout boards, ADC breakout boards, Microphone breakout boards, and audio-connector breakout boards, and – despite its diminutive size – it manages to provide all of that functionality in a single board. And it dos so without compromising signal quality.

Wouldn't it be cool to drive a tiny OLED display, read a color sensor, or even just flash some LEDs directly from your computer? Sure you can program an Arduino or Trinket to talk to these devices and your computer, but why can't your computer just talk to those devices and sensors itself? Well, now your computer can talk to devices using the Adafruit FT232H breakout board! What can the FT232H chip do? This chip from FTDI is similar to their USB to serial converter chips but adds a 'multi-protocol synchronous serial engine' which allows it to speak many common protocols like SPI, I²C, serial UART, JTAG, and more! There's even a handful of digital GPIO pins that you can read and write to do things like flash LEDs, read switches or buttons, and more. The FT232H breakout is like adding a little swiss army knife for serial protocols to your computer! This chip is powerful and useful to have when you want to use Python (for example) to quickly iterate and test a device that uses I²C, SPI or plain general purpose I/O. There's no firmware to deal with, so you don't have to deal with how to 'send data to and from an Arduino which is then sent to and from' an electronic sensor or display or part. This breakout has an FT232H chip and an EEPROM for onboard configuration. Specifications Dimensions: 23 x 38 x 4 mm (0.9 x 1.5 x 0.2') Weight: 3.4 g Downloads CAD Files

ESP32-S3-EYE is a small-sized AI development board. It is based on the ESP32-S3 SoC and ESP-WHO, Espressif’s AI development framework. The ESP32-S3-EYE board consists of two parts: the main board (ESP32-S3-EYE-MB) features the ESP32-S3-WROOM-1 module, a 2-Megapixel camera, a SD card slot, a digital microphone, a USB port, and function buttons; and the sub board (ESP32-S3-EYE-SUB) integrates an LCD display. The main board and sub board are connected through pin headers. ESP32-S3-EYE offers plenty of storage, with an 8 MB Octal PSRAM and a 8 MB flash. It also supports image transmission via Wi-Fi and debugging through a Micro-USB port. Specifications Camera The 2 MP camera OV2640 has a 66.5° field of view and a maximum resolution of 1600x1200. You can change the resolution when developing applications. Module Power LED The LED (green) turns on when USB power is connected to the board. If it is not turned on, it indicates either the USB power is not supplied, or the 5 V to 3.3 V LDO is broken. Software can configure GPIO3 to set different LED statuses (turned on/off, flashing) for different statuses of the board. Note: GPIO3 must be set up in open-drain mode. Pulling GPIO3 up may burn the LED. Pin Headers Connect the female headers on the sub board. 5 V to 3.3 V LDO Power regulator that converts a 5 V supply into a 3.3 V output for the module. Digital Microphone The digital I²S MEMS microphone features 61 dB SNR and –26 dBFS sensitivity, working at 3.3 V. FPC Connector Connects the main board and the sub board. Function Button There are six function buttons on the board. Users can configure any functions as needed except for the RST button. ESP32-S3-WROOM-1 The ESP32-S3-WROOM-1 module embeds the ESP32-S3R8 chip variant that provides Wi-Fi and Bluetooth 5 (LE) connectivity, as well as dedicated vector instructions for accelerating neural network computing and signal processing. On top of the integrated 8 MB Octal SPI PSRAM offered by the SoC, the module also comes with 8 MB flash, allowing for fast data access. ESP32-S3-WROOM-1U module is also supported. MicroSD Card Slot Used for inserting a MicroSD card to expand memory capacity. 3.3 V to 1.5 V LDO Power regulator that converts a 3.3 V supply into a 1.5 V output for the camera. 3.3 V to 2.8 V LDO Power regulator that converts a 3.3 V supply into a 2.8 V output for the camera. USB Port A Micro-USB port used for 5 V power supply to the board, as well as for communication with the chip via GPIO19 and GPIO20. Battery Soldering Points Used for soldering a battery socket to connect an external Li-ion battery that can serve as an alternative power supply to the board. If you use an external battery, make sure it has built-in protection circuit and fuse. The recommended specifications of the battery: capacity > 1000 mAh, output voltage 3.7 V, input voltage 4.2 V – 5 V. Battery Charger Chip 1 A linear Li-ion battery charger (ME4054BM5G-N) in ThinSOT package. The power source for charging is the USB Port. Battery Red LED When the USB power is connected to the board and a battery is not connected, the red LED blinks. If a battery is connected and being charged, the red LED turns on. When the battery is fully charged, it turns off. Accelerometer Three-axis accelerometer (QMA7981) for screen rotation, etc.

The iCEBreaker FPGA board is an open-source educational FPGA development board.
The iCEBreaker is great for classes and workshops teaching the use of the open source FPGA design flow through Yosys, nextpnr, IceStorm, Icarus Verilog, Amaranth HDL and others. This means the board is low cost and has a nice set of features to allow for the design of interesting classes and workshop exercises. At the same time it allows the user to use the proprietary vendor tools if they choose to.
After the workshop the boards can be easily used as a development board as most GPIO are exposed, broken out and configurable through jumpers on the back of the board. There is only a minimal amount of buttons and LED that can't be disconnected and used for your own purposes.
