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.

The SparkFun GPS-RTK2 raises the bar for high-precision GPS and is the latest in a line of powerful RTK boards featuring the ZED-F9P module from u-blox. The ZED-F9P is a top-of-the-line module for high accuracy GNSS and GPS location solutions, including RTK capable of 10 mm, three-dimensional accuracy. With this board, you will be able to know where your (or any object's) X, Y, and Z location is within roughly the width of your fingernail! The ZED-F9P is unique in that it is capable of both rover and base station operations. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins if you prefer to use a breadboard.
We've even included a rechargeable backup battery to keep the latest module configuration and satellite data available for up to two weeks. This battery helps 'warm-start' the module decreasing the time-to-first-fix dramatically. This module features a survey-in mode allowing the module to become a base station and produce RTCM 3.x correction data.
The number of configuration options of the ZED-F9P is incredible! Geofencing, variable I²C address, variable update rates, even the high precision RTK solution can be increased to 20 Hz. The GPS-RTK2 even has five communications ports which are all active simultaneously: USB-C (which enumerates as a COM port), UART1 (with 3.3 V TTL), UART2 for RTCM reception (with 3.3V TTL), I²C (via the two Qwiic connectors or broken out pins), and SPI.
Sparkfun has also written an extensive Arduino library for u-blox modules to easily read and control the GPS-RTK2 over the Qwiic Connect System. Leave NMEA behind! Start using a much lighter weight binary interface and give your microcontroller (and its one serial port) a break. The SparkFun Arduino library shows how to read latitude, longitude, even heading and speed over I²C without the need for constant serial polling.

The Home Automation HAT uses only pluggable connectors. In addition, the latest release (V4.0 and up) has two new communication ports: 1-Wire and RS485. The card uses only 5 V power. On-board step-up power supply generates 12 V to power the 0-10 V analog outputs. A general purpose push-button, wired directly to a Raspberry Pi GPIO pin, can be used to shut down Raspberry Pi without a keyboard, or to force any output to a desired state. Ideal solution for your Raspberry Pi Home Automation projects. Read temperatures in up to 8 zones with analog inputs. Control your heating and cooling system with the 8 onboard relays. Use the 8 optically isolated digital inputs for your security system. Activate the hardware watchdog to monitor and power cycle the Raspberry Pi in case of software lockup. Control four-light systems with the four PWM open-drain outputs (you supply external power up to 24 V). Control four light dimmers using 0-10 V outputs. Compatibility The card is compatible with all Raspberry Pi versions from Zero to 4. It shares the I²C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards. This feature leaves the remaining 24 GPIOs available for the user. Power Requirements The Home Automation card needs 5 V to operate and can be powered from Raspberry Pi or from its own pluggable connector. The onboard relay coils are also powered from the 5 V. An on-board 5V to 12V step-up power supply generates the voltage to drive the 0-10 V analog outputs. A local 3.3 V regulator powers the rest of the circuitry. The card needs 50 mA to operate with all relays off. Each relay needs up to 80 mA to turn on. Relays The 8 on-board relays have contacts brought out to heavy duty pluggable connectors, which make the card easy to use when multiple cards are stacked up. Relays are grouped in two sections of four relays each, with one common terminal and one N-O contact for each relay. Relays are rated 10 A/24 VDC and 250 VAC, but due to the board geometry limitation, the relays can switch only 3 A and 24 V, AC or DC. Status LEDs show when RELAYS are ON or OFF. Stacking Multiple Cards Up to eight Home Automation cards can be stacked on your Raspberry Pi. Each card is identified by jumpers you install to indicate the level in the stack. Cards can be installed in any order. The three position jumper on the upper right corner of the card selects the stack level.

Ulanzi TC001 is an LED pixel clock consisting of 256 individual addressable RGB LEDs (8x32) with built-in battery, buzzer, light, temperature and humidity sensor. The integrated rechargeable battery offers a runtime of up to 5 hours. The WiFi connection to the clock is made via an ESP32 chip. Ulanzi TC001 uses an ESP32-WROOM-32D module.
Features
Pixelated message display
Simultaneous Display of the Number of Followers: Fan growth is immediately visible, suitable for YouTube, Bilibili, and Weibo.
Pomodoro Clock Design: Manage your own time more scientifically.
Explore unlimited possibilities: Multiple programs need to be installed through the control server to achieve more functions.
Awtrix Makes it Better: Awtrix simulator in TC001’s firmware simulates an Awtrix matrix and allows you to control the clock using a standard Awtrix host.
Hi-tech and stunning appearance: Modeling simple atmosphere, LED full-color pixel screen with better imaging.
Built-in 4400 mAh battery with up to 5 hours of battery life.

With a 6x20 grid of 2.54 mm spaced holes for easy soldering and labelled Pico pins so you know what's what, Pico Proto is perfect for when you're happy with your breadboard project and want to give it a secure, smart and compact long-term home. Pico Proto doesn't come with any headers attached, so you will need to either solder it directly to your Pico's male header pins (for a permanent, but super slim sandwich) or solder it to some female header. Features 40 2.54 mm spaced holes for attaching to your Pico. 120 2.54 mm spaced holes (6x20 grid) for attaching other things Compatible with Raspberry Pi Pico. Dimensions: approx 51 x 25 x 1 mm (L x W x H)
The HuskyLens AI Camera intuitive design allows the user to control different aspects of the camera just by pressing buttons. You can start and stop learning new objects and even switch between algorithms from the device.
To further reduce the need to be connected to a PC the HuskyLens AI Camera comes with a 2-inch display so you can see what's going on in real time.
