ESP32-S3-based kit allows you to build an Internet Radio with a touchscreen display

The ESP32 Internet Radio from Poland-based maker, The MicroMaker, is a simple hardware kit that combines the LilyGo T-Display S3 Development board with an I2S audio breakout module and other components to form a radio that can access and stream from online radio stations. With the ESP32 Internet Radio, you are not limited to the radio stations available in your immediate vicinity. It is powered by the LilyGo T-Display S3 which integrates the network-capable ESP32-S3 microcontroller (Wi-Fi + BLE 5), a 1.9” full-color capacitive touchscreen display, and two programmable buttons. The ESP32-S3’s integrated Wi-Fi capability allows the radio to connect to the Internet, and the touchscreen brings an intuitive and easy-to-use interface to the device. It supports up to 512 stored radio stations, and you can manage these stations from a web browser on your PC or mobile phone. The Internet Radio can be powered by an 18650 Lithium-ion battery […]

picoLLM is a cross-platform, on-device LLM inference engine

Large Language Models (LLMs) can run locally on mini PCs or single board computers like the Raspberry Pi 5 but with limited performance due to high memory usage and bandwidth requirements. That’s why Picovoice has developed the picoLLM Inference Engine cross-platform SDK optimized for running compressed large language models on systems running Linux (x86_64), macOS (arm64, x86_64), and Windows (x86_64), Raspberry Pi OS on Pi 5 and 4, Android and iOS mobile operating systems, as well as web browsers such as Chrome, Safari, Edge, and Firefox. Alireza Kenarsari, Picovoice CEO, told CNX Software that “picoLLM is a joint effort of Picovoice deep learning researchers who developed the X-bit quantization algorithm and engineers who built the cross-platform LLM inference engine to bring any LLM to any device and control back to enterprises”. The company says picoLLM delivers better accuracy than GPTQ when using Llama-3.8B MMLU (Massive Multitask Language Understanding) as a […]

Rockchip RK2118G/RK2118M dual-core Star-SE Armv8-M microcontrollers target smart audio applications

Rockchip RK2118G microcontroller block diagram

Rockchip RK2118G and RK2118M smart audio microcontrollers based on a dual-core Star-SE Armv8-M processor, an NPU for smart AI audio processor, three DSPs, 1024KB SRAM, optional DDR memory in package, and a range of peripherals. I first noticed the RK2118M in slides from the Rockchip Developer Conference 2024 last March, but I did not have enough information for an article at the time. Things have now changed since I’ve just received a bunch of datasheets including the one for the RK2118G and RK2118G microcontrollers, which look identical except for the DDR interface and optional built-in 64MB RAM for the RK2118G. The datasheets have only one reference to Arm with the string “Arm-V8M” and nothing else, and Cortex is not mentioned at all. But the slide above reveals the STAR-SE core looks to be an Arm Cortex-M33 core. We also learn the top frequencies for the “STAR-M33″/”STAR-SE” core (300MHz) and the […]

Sonocotta’s ESParagus “Media Center” is a series of ESP32-based, open-source audio streamers (Crowdfunding)

ESParagus Media Center is a line of audio streamers from Sonocotta, all powered by an ESP32 microcontroller module. It includes the ESParagus HiFi MediaLink, Loud ESParagus, and the Louder ESParagus. The ESP32-based audio centers can be used to power old stereo speaker systems that lack streaming capabilities. They are completely open-source, consume little power when not in use, and boot up in seconds. The ESParagus Media Center products are based on the ESP32-WROVER microcontroller module with Wi-Fi and Bluetooth connectivity and an onboard PSRAM chip. They are fitted with an external Wi-Fi antenna and the top-end model – the Louder ESParagus – is fitted with a W5500 LAN chip for Ethernet networking. All three ESParagus Media Centers run squeezelite-esp32 firmware which supports Spotify Connect, Apple AirPlay, and Logitech Media Server. Integrations with Home Assistant are possible and can be useful for multi-room configurations. The Louder ESParagus is quite similar to […]
