Giveaway Week – RockPi 4C SBC

The first, but not last, SBC of Giveaway Week 2020 is RockPi 4C single board computer equipped with a Rockchip RK3399 processor coupled with 4GB RAM, and featuring HDMI and DisplayPort for dual 4K monitor setups, as well as Gigabit Ethernet, WiFI 5, Bluetooth, USB 3.0/2.0 ports, etc… The board closely follows Raspberry Pi 4 form factor, so without thinking too much about it I thought I could just use it with CrowPi2 Raspberry Pi 4 laptop. However due to small mechanical differences, and a different position of the processor impacting cooling, I quickly realized this would not work. Since I did not have time to review yet another RK3399 SBC, I thought I might as well as give it away, as I’m sure somebody will find a good use for it. Note the board does not come with any accessories, so you’ll have to get a MicroSD card, USB-C […]

Telink TLSR9 Wireless Audio & IoT RISC-V SoC integrates RISC-V DSP/SIMD P-extension

At the end of last month, there was a lot of buzz about Bouffalo BL602, one of the first RISC-V SoC with built-in wireless connectivity, namely WiFi 4 and Bluetooth 5.0 LE. We should expect more and more of those types of solutions, and Telink & Andes jointly introduced TLSR9-series of wireless audio chips for hearables, wearables, and other high-performance IoT applications. The chips are powered by an Andes D25F RISC-V 5-stage core that happens to be the first core to integrate RISC-V DSP/SIMD P-extension and offer Bluetooth 5.2, Zigbee 3.0, HomeKit, 6LoWPAN, Thread, and/or 2.4 GHz proprietary protocol. The press release focuses on the Andes core, but an article in Chinese allows use to find more about Telink TLSR9 family’s key features: CPU – Andes D25F 32-bit RISC-V 5-stage core @ up to 96 MHz (2.59 DMIPS/MHz and 3.54 CoreMark/MHz) with RISC-V DSP/SIMD P-extension Optional NNU – AI engine […]

Giveaway Week – Miniware DT71 Smart Tweezers

Day 2 of Giveaway Week 2020 on CNX Software. What do we have here? Miniware DT71 smart tweezers that serve as LCR meter, basic signal generator, and of course actual tweezers. I found DT71 to be a useful tool for electronics enthusiasts and engineers for checking out SMT (and DIP) components, debugging boards, and even generating signals for testing. When connected to a PC, it will show as a USB storage device that you can use to adjust settings or upgrade the firmware. To enter the draw simply leave a comment with your country and whatever else you’d like to say. If the country is missing, I’ll consider the entry void.
