$9.9 ROCK Pi S is a Tiny SBC Powered by Rockchip RK3308 Processor

Radxa launched their low cost ($40) Rock Pi 4 SBC powered by Rockchip RK3399 processor a little over 18 months ago. If you are subscribed to their mailing list, the company has now sent an email entitled “ROCK Pi Summer Updates 2019” (no link available) that reports about v1.4 of the board with 4MB SPI flash onboard, an external WiFi antenna connector, and various other small changes, as well as the announcement of RockPi PoE HAT to power the board from an Ethernet cable, and an USB 3.0 eMMC card reader. But what particularly caught my attention in the email was a new tiny single board computer powered by Rockchip RK3308 Cortex-A35 processor: Rock Pi S selling for as low as $9.9 with 256MB RAM, and targetting headless IoT & smart voice applications. Rock Pi S board specifications: SoC – Rockchip RK3308 quad-core Arm Cortex-A35 processor with built-in VAD (Voice […]

Mcuzone RK3308 SoM and MDK3308-EK Evaluation Kit are Designed for Smart Voice Applications

Mcuzone MDK3308-EK Rockchip-RK3308 Development Board

Rockchip RK3308 is a quad-core Cortex-A35 processor that was announced in 2018 together with RK3326 specifically for Smart AI solutions. While the processor is equipped with an RGB LCD output interface, it does not come with a 2D or 3D graphics accelerator, so it’s better suited to smart speakers with an optional display using a basic user interface. I’ve not seen many hardware platforms or boards based on the processor, but today I noticed “Hangzhou Wild Chip Tech” had an RK3308 system-on-module, as well as development kits for sale on Aliexpress with the module price starting at $23. Mcuzone MDK3308 Coreboard Specifications: SoC – Rockchip RK3308 quad-core Cortex-A35 processor @ 1.3 GHz with NEON and VFPv4 FPU System memory / storage configurations: 256MB DDR3/3L + 256MB NAND flash 512MB DDR3/3L + 8GB eMMC flash 2x 100-pin dual row headers (1.27mm pitch) exposing: Display – LCD interface up to 1024×600 (RGB), […]

FOSSASIA 2019 Schedule – March 14-17

As its name implies, FOSSASIA is a Free and Open Source Software event taking place every year in Asia, more specifically in Singapore. I first discovered it last year, and published a virtual FOSSASIA 2018 schedule last year to give an idea about the subjects discussed at the event. It turns out FOSSASIA 2019 is coming really soon, as in tomorrow, so I’m a bit late, but I’ll still had a look at the schedule and made my own for the 4-day event. Thursday – March 14, 2019 10:05 – 10:25 – For Your Eyes Only: Betrusted & the Case for Trusted I/O by Bunnie Huang, CTO Chibitronics Security vulnerabilities are almost a fact of life. This is why system vendors are increasingly relying on physically separate chips to handle sensitive data. Unfortunately, private keys are not the same as your private matters. Exploits on your local device still have […]

$16 ESP32-A1S ESP32 Audio Development Kit Comes with 2 Microphones, Audio Jacks & Headers

Espressif ESP32 WiSoC can be integrated into various applications, and earlier this year Espressif Systems released ESP32 LyraTD MSC Audio Mic HDK (Hardware Development Kit) which I could test with Baidu DuerOS using Mandarin. Since then the company released the ESP-ADF Audio Development Framework that beside Baidu DuerOS, now supports Google Assistant and Amazon Alexa, so you don’t need to speak or learn Chinese to use the kit! 🙂 Another ESP32 audio board was the similarly named ESP32-LyraT, and now we have at least more more option with Seeed Studio selling ESP32-A1S WiFi + Bluetooth ESP32 audio development kit for $16.90 on their store. ESP32-A1S ESP32 audio development kit specifications: Wireless Module A.I. Thinker ESP32-A1S module based on ESP32 dual core Tensilica CPU clocked at up to 240MHz with 520 KB SRAM, and 8MB on-module PSRAM 802.11 b/g/n WiFi and Bluetooth 4.2 LE Storage – Micro SD card slot up […]
