Louder Raspberry Pi is an open-source home media center that is powered by Raspberry Pi Zero and a TI TAS5805M DAC

Louder Raspberry Pi is an open-source home media center based on a combination of the Raspberry Pi Zero W or Zero 2 W and the Texas Instruments TAS5805M DAC. It is an audio entertainment platform created by Andriy Malyshenko of Sonocotta, a Polish electronics hobbyist and maker. Louder Raspberry Pi incorporates the computing power of the Raspberry Pi Zero and the Hi-Fi audio processing capabilities of TI’s TAS5805M DAC in a compact, aluminum case. The device delivers up to 25W per channel stereo output and is powered via a 65W+ USB-C PD3.0 adapter. It is “aimed to be paired with medium-to-large speaker systems” and supports both Wi-Fi and Ethernet. The Raspberry Pi board was selected over other lightweight alternatives due to the ease of development it offers. The Raspberry Pi Zero board is small enough to make for an overall compact device and powerful enough to handle the demands of […]

SB Components’ Trekko Pico is an open-source, RP2040-powered GPS logger with multi-GNSS support

After the success of their Kickstarter campaign, SB Components has now made the Trekko Pico GPS logger available for pre-order. The Trekko Pico is a small location logger for travelers and outdoor enthusiasts that makes it easy to track routes and record their travels. A Raspberry Pi RP2040 powers the Trekko Pico, providing the programming, connectivity, and data logging functionality. The Quectel GNSS L76K module supports the concurrent reception of GPS, GLONASS (or BeiDou), Galileo, SBAS, and QZSS signals, with 32 tracking and 72 acquisition channels. There is a JST 2-pin connector that can be used to attach an external battery, and the Microchip MCP73831 controller is responsible for battery charging and management. Also, users can slot a coin cell into the holder at the back of the board to power a real-time clock for data backup purposes. Potential applications for the Trekko Pico GPS logger include surveillance, telematics, Geographic […]
