Allwinner T2 is a Rebranded Allwinner A20 Processor Operating in Industrial Temperature Range

Last month, Allwinner unveiled A40 and A60 industrial and military grade processors leveraging IP blocks from the old-but-popular Allwinner A20 dual core processor. This is good news for software support, as A40 and A60 should hopefully become supported in U-boot and the Linux kernel without too many efforts, as well as for companies or makers requiring wider temperature ranges in their products. However, those new processors were not pin-to-pin compatible with Allwinner A20, so a PCB redesign would be required. That’s where Allwinner T2 comes into play, as reported by Olimex, it is a rebranded Allwinner A20 dual core Cortex A7 processor with an industrial temperature range (-40 to +85 °C) that makes it suitable for automotive infotainment. I actually covered Allwinner T2 back in 2015, but at the time Allwinner did not mention anything about temperature range, and SATA support – found in A20 – was not shows in […]

Arm Announces Cortex-A76 CPU with Laptop-class Performance, Mali-G76 GPU, Mali-V76 8K VPU

Arm Cortex A75 based processors are only found in a few SoCs and devices, but Arm keeps on innovating, and they’ve now announced a new suite of of IP with Cortex-A76 CPU enabling 35 percent more performance, and Mali-G76 GPU with ML support and 30 percent higher efficiency and performance. SoC based on those new CPU and GPU IP will provide “laptop-class” performance, and the company also announced Arm Mali-V76 VPU with support for 8K video decoding and encoding. Arm Cortex A76 After Cortex A75, the Arm Cortex-A76 CPU is the second high performance processor core based on DynamIQ technology, and beside the 35 percent performance gain mentioned in the introduction, it also offers 40 percent improved efficiency, as well as delivers 4x compute performance improvements for AI/ML at the edge. Highlights of Cortex A76: Architecture – Armv8-A (Harvard) with Armv8.1, Armv8.2, Armv8.3 (LDAPR instructions only), cryptography and RAS extensions […]

Banana Pi BPI-S64 Core is a “Compute Module” based on Actions Semi S700 Processor

SinoVoIP has launched many development boards & SBCs under the Banana Pi brands, but so far they had not designed any system-on-modules (SoM). Banana Pi BPI-S64 Core is their first SoM, which they refer to as “Compute Module” for the compulsory Raspberry Pi reference, and it’s not based on Allwinner or Realtek processors used in many of their recent boards, but instead an Actions Semi S700 quad core Cortex A53 processor. Banana Pi BPI-S64 Core specifications: SoC – Actions Semi S700 quad core Arm Cortex-A53 processor with Arm Mali-450MP4 GPU with OpenGL ES2.0/1.1, OpenVG 1.1, EGL 1.5 support System Memory – 2GB LPDDR3 Storage – 8GB eMMC flash Edge Connector – 204-pin SO-DIMM connector Power Supply – PMIC on-board Dimensions – 67.5 x 30 mm The company also provides Banana pi BPI-S64 core kit for getting started with the module. Development kit preliminary specifications: SODIMM slot for Banana BPI-S64 Core […]

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 – […]

Intel Launches Optane DC Persistent Memory Compatible with DDR4 DIMMs

Intel and Micron jointly announced 3D Xpoint technology in 2015 that promised to be 1,000 times faster and endurant than NAND flash, and 10 times denser than conventional DRAM. Products were launched in 2017 under the Optane brand with somewhat lower specifications starting with enterprise PCIe SSDs, followed by Optane M.2 cards, and Optane PCIe SSDs for the consumer market which do improve performance for very specific tasks. But beside storage devices, Intel also planned to launch Optane memory that fits into RAM slot, and they’ve finally done that with their Optane DC Persistent Memory fitting into DDR4 DIMMs with capacity ranging from 128GB to 512GB. The Optane DC Persistent Memory modules are made for the datacenter, and will be supported by the next generation of Intel’s Xeon server platforms. The module are sampling now with mass production planned for later this year, but only to select customer. Broad availability […]

My Sonoff TH16 Wireless Switch is Dead – Postmortem Analysis

Back in November 2016, I connected Sonoff TH16 WiFi switch to my water pump, and since then it worked fairly well, except for the occasional “offline error” in eWelink app, which was usually solved with a power cycle. But in the last couple of days, I noticed the pump would not start at the set time, and I could not control it using the Android app either, even after turning on and off the power. So I took it out to have a look, and one component indeed burnt. ITEAD Studio released the schematics in the Wiki, and the dead component is connected to a GND as well as to a transistor, so it must be R2 4.64 Ohm resistor [Corrected from R3 resistor after checking board with multimeter]. But what may have caused this? Resistors burn because too high of a current flows through them. We often have micro […]

MakerSpot CC2640 is a $20 Bluetooth 5 LE USB Dongle

Bluetooth 5 was announced in May 2016 with four times the range, twice the speed of Bluetooth 4.0. Since then SoCs, development boards, and smartphones have been announced with Bluetooth 5, but so far I had not seen any Bluetooth 5 USB dongle to add the new Bluetooth version to existing computer or boards. While I’ve not been able to find a consumer grade Bluetooth 5 USB dongle yet, today I found out something close it to with MakerSport CC2640 USB dongle / board based on TI CC2640 chip. GT-Tronics CC264BPA-UDOG (actual name) USB dongle specifications: MCU – Texas Instrument CC2640R2F Arm Cortex-M3 SimpleLink Wireless SoC with Bluetooth 5.0 Connectivity – Bluetooth 5 Low Energy BLE including built-in antenna; backward compatible with BLE 4.0, 4.1, 4.2 Silabs CP2110 HID to UART bridging device Debugging – 10-pins JTAG connector for CC2640 debugging and firmware flashing The dongle is enumerated as generic HID […]
