Datanoise PicoADK v2 music synthesizer is a Raspberry Pi RP2350 board for audio experimentation

PicoADK v2 Synthesizer Development Platform

After the success of PicoADK v1, Datanoise has recently announced the launch of its PicoADK v2 music synthesizer built around the Raspberry Pi RP2350 MCU. The board supports projects like custom synthesizers, audio effects, and noise generation, and the 8 MB QSPI PSRAM of the RP2350 makes it ideal for memory-intensive applications such as long delays. Additionally, it features a SWD debug port, microSD card support, a MIDI-in circuit with an optocoupler, USB Type-C, user and power LEDs, and more. Previously, we have written about various similar synthesizer boards, like the Arduino-based MIDI controller, and we have seen products like the TinyLlama x86 retro computer, which uses the Raspberry Pi Zero 2 W as a MIDI synthesizer.

DeepRad is a cheap, modular SDR receiver based on the RTL-SDR (Crowdfunding)

Deeprad Single modular SDR receiver

DeepRad is a software-defined radio (SDR) receiver built in the RTL-SDR form factor. The modular SDR receiver offers advantages over other RTL-SDR-based devices which make it easier to integrate with other components and build custom solutions for your specific applications. The DeepRad SDR receiver is based on the RTL-SDR dongle and features the same Realtek RTL2832U demodulator chip with an R860T tuner. The module features D+ and D- pins for USB connection, V+ for 5 V power supply, solderable jumpers for oscillator selection, an RF pin for antenna connection, and 8 shield pin connectors for shielding and support. The module is targeted at custom designs, with the user free to choose the best components for their application. It is as versatile as a typical SDR receiver, with applications ranging from FM radio listening to aircraft tracking. We have previously covered other RTL-SDR receivers, such as the KrakenSDR and the RTL-SDR […]
