Sony SPRESENSE Arduino Compatible GNSS + Audio IoT Board To Sell for $50 (in Japan)

Last year, we covered Sony Spritzer, an Arduino compatible with a Sony hexa-core Arm Cortex-M4F micro-controller, a built-in GNSS receiver, and an audio codec. The product page for this product is now gone, but it appears Sony only renamed it to SPRESENSE, made some design modifications, and is ready to launch the main board for 5,500 JPY (~$50), and the extension board for an extra 3,500 JPY ($32) on July 31, 2018. Sony SPRESENSE main board (CXD5602PWBMAIN1) specifications: MCU – Sony CXD5602 ARM Cortex-M4F ×6 micro-controller clocked at up to 156 MHz with 1.5MB SRAM Storage – 8MB Flash Memory GNSS – GPS & GLONASS Audio – 3.5mm audio jack Expansion I/Os Digital I/O Pins – GPIO, SPI, I2C, UART, PWM, I2S Analog Pins – 2ch (0.7V range) Camera interface USB – 1x micro USB port for programming and power Power Supply – 5V via micro USB port Dimensions – […]

Measy RCA220 is a $35 Wireless AV Transmitter / Receiver Kit with a 200m Range

There are several ways to send video & audio data over a distance without using long cables, from professional DVB-T transmitters with up to 10km range, to cheaper DIY SDR solutions with a shorter range , and HDMI transmitters leveraging your existing electrical cables. Those all work for different target applications (drones, video signal extender), but cost at least a few hundred dollars. If you just intend to transmit composite video (PAL/NTSC) and audio within a house or building, Measy RCA220 will be a more cost effective solution with a range of up to 200 meters. Measy RCA220 AV transmitter / receiver specifications: Connectivity – 2.4GHz wireless transmission with up to 200m range; built-in antenna, 8x selectable channels Video / Audio Ports Transmitter – RCA composite input, 2x RCA L/R audio input Receiver – RCA composite output, 2x RCA L/R audio output Misc – IR jack, channel selection button, front […]

Google AIY Projects Kits are Easier to Use in 2018 with Raspberry Pi Zero WH and All Accessories Included

Google launched two AIY Projects kits last year with a Voice Kit that took a Raspberry Pi 3 to create a smart speaker, and a Vision kit for hardware accelerated computer vision using a Raspberry Pi Zero W board. Google reports the kits are popular, especially for STEM education, but educators/parents had to buy the Raspberry Pi boards and micro SD cards themselves, as well as flash the firmware to the cards. So the company decided to redesign both kits to work with the Raspberry Pi Zero WH (RPi Zero W with headers), and include it inside the box with cable and pre-provisioned SD card, so kids can get started faster with experimentation with having to setup the kits. So that means we now have AIY Projects Voice Kit v2 with RPi Zero WH and micro SD card with firmware, as well as AIY Projects Vision Kit v1.1 with RPi Zero […]

Yamaha RX-V385 A/V Receiver to Support eARC (part of HDMI 2.1 specifications)

HDMI 2.1 promises features such as 8K/10K video output, dynamic HDR, or enhanced audio return channel (eARC), but so far I had not seen any hardware boasting support for the new specifications. It’s not really surprising, as the HDMI Compliance Test Specifications (CTS) for HDMI 2.1 is expected to be released in stages starting in Q2 2018. While I have yet to see any HDMI 2.1 capable TV, Yamaha is already showing off a 5.1 A/V receiver allegedly HDMI 2.1 via their upcoming RX-V385 model that will be sold for $299.95 in the US. Key features listed by the company: 5.1-Channel powerful surround sound Bluetooth for wireless connectivity HDMI 2.1 with HDCP 2.2 (4 in/1 out) 4K Ultra HD support, HDR10, Dolby Vision, Hybrid Log-Gamma and BT.2020 YPAO auto-calibration technology for ideal sound That looks good, and if we look into the details specifications we can see HDMI eARC (part […]
