POWKIDDY X18 is a Low Cost Portable Android Game Console Powered by MediaTek MT8163 SoC

GPD XD Plus handheld Android game console launched about nearly one year ago with a MediaTek MT8176 hexa-core Arm Cortex-A72/A53 processor, and a 5.0″ display, and is now sold for under $210. But there’s now another portable game console that appears heavily inspired from GPD design, but featuring a low end MediaTek MT8163 quad core Cortex A53 processor instead, as well as a slightly larger 5.5″ display. Meet POWKIDDY X18. POWKIDDY X18 hardware specifications: SoC – MediaTek MT8163 quad core Cortex A53 processor @ 1.3GHz with Arm Mali-T720 GPU System Memory – 2GB LPDDR3 Storage – 16GB eMMC flash, microSD card Display – 5.5″ IPS Screen with 1280 x 720 resolution, 5-point capacitive touchscreen Video Output – HDMI port Connectivity – WiFi 4 802.11 a/b/g/n, Bluetooth: 4.0 USB – 1x micro USB port (for charging only?) Buttons – Power button, D-Pad, A/B/X/Y buttons, L1/L2/R1/R2, left & right joysticks, Start & […]

$15 Sparkfun Edge Board Supports Tensorflow Lite for Microcontrollers

The 2019 TensorFlow Dev Summit is now taking place, and we’ve already covered the launch of Google’s Coral Edge TPU dev board and USB accelerator supporting TensorFlow Lite, but there has been another interesting new development during the event: TensorFlow Lite now also supports microcontrollers (MCU), instead of the more powerful application processors. You can easily get started with Tensorflow Lite for MCU with SparkFun Edge development board powered by Ambiq Micro Apollo3 Blue Bluetooth MCU whose ultra-efficient Arm Cortex-M4F core can run TensorFlow Lite using only 6uA/MHz. SparkFun Edge specifications: MCU – Ambiq Micro Apollo3 Blue 32-bit Arm Cortex-M4F processor at 48MHz / 96MHz (TurboSPOT) with DMA, 1MB flash, 384 KB SRAM, 6uA/MHz power usage, Bluetooth support. Connectivity – Bluetooth LE 5 (on-chip) + Bluetooth antenna Camera – OV7670 camera connector Audio – 2x MEMS microphones with operational amplifier Sensor – STMicro LIS2DH12 3-axis accelerometer Expansion – Qwiic connector, […]

GameShell Kit Review – Part 2: An Hackable Retro Gaming Console

ClockworkPi GameShell is an hackable retro gaming console combining Arm Linux and Arduino boards that happens to come in kit form, and that’s lot of fun to assemble as we’ve seen in the first part of the review of ClockworkPi GameShell. Since then I’ve had time to have more fun, play some games, and experiment with the device, so I’ll report my experience and point out the good parts, as well as some of the shortcomings I came across. We can press the power button to start it up, and after a few seconds we get to the main menu with several icons including… the self-describing Settings, Retro Games with MAME, MGBA, NESTOPIA, and PCxs emulators that require your own ROMs/BIOS, as well as Indie Games with ready to play games like OpenTyrian spaceship shooting game, or NyanCat. Moving on to the right of the menu we’ve got the famous […]

Seeeduino Lotus Cortex-M0+ is a $10 Arduino compatible Board with 12 Grove Connectors

Grove modules are cool little add-on boards that connect through 4-pin header using UART, I2C, analog or digital I/Os, and usually you’d need to buy a HAT or shield to connect them to respectively Raspberry Pi or Arduino board. But Seeed Studio has come up with a small Arduino compatible board based on Microchip SAMD21 microcontroller called Seeeduino Lotus Cortex-M0+ that may be the cheapest “Grove” solution around as it sells for just $9.90. Seeeduino Lotus Cortex-M0+ specifications: MCU – Microchip Atmel SAMD21 Arm Cortex-M0+ microcontroller at 48MHz with 256KB Flash and 32KB SRAM as found in Arduino Zero. USB – 1x micro USB port for power and programming Expansion 12x on-board Grove connectors (6x Digital, 3x Analog, 1x UART and 2x I2C) Arduino UNO headers 14x Digital I/O Pins (10 PWM outputs) 6x Analog Inputs I/O pins are 3.3V, do not input more than 3.3V, otherwise the CPU may […]

TI AM5729 Powered BeagleBone-AI Comes with TI C66x DSP and EVE Cores

Launched in 2013, BeagleBone Black is still one of the most popular hobbyist board thanks to its many I/Os, software support, and affordable price with being the cheapest board around those days. But it looks like we’ll soon have a new version that allows to experiment with artificial intelligence workloads. BeagleBone-AI is powered by Texas Instruments AM5729 SoC equipped with TI C66x digital-signal-processor (DSP) cores and embedded-vision-engine (EVE) cores supported through a TIDL (Texas Instruments Deep Learning) machine learning OpenCL API. BeagleBone-AI preliminary specifications: SoC – TI AM5729 dual core Cortex-A15 processor featuring 4 PRUs, Dual core C66x DSP, and 4 EVEs System Memory – 1GB RAM Storage – 16GB on-board eMMC flash with high-speed interface Networking – Gigabit Ethernet and high-speed WiFi SB – 1x USB type-C for power and superspeed dual-role controller, 1x USB type-A host Expansion – BeagleBone Black (BBB) compatible headers Dimensions – 86.4 x 53.4 […]

Snapdragon 8cx 5G Compute Platform Targets 5G always on, always connected PCs

Qualcomm announced Snapdragon 8cx processor for so-called always on, always connected mobile PCs in December 2018. The processor comes with eight Qualcomm Kryo 495 core, an Adreno 680 GPU with a 128-bit memory interface, NVME SSD, UFS 3.0 support, as well as a Snapdragon X24 4G LTE modem among other features. But the launch 5G cellular connectivity will start to (slowly) take off this year, so the company also revealed plans for Snapdragon 8cx 5G compute platform that brings the same processing power as 8cx processor but with an extra Snapdragon X55 5G modem. The company did not provide that many details about Snapdragon 8cx 5G in the press release, but we already know Snapdragon 8cx specifications as well as the key features of Snapdragon X55 2nd generation 5G modem, so we should already have a good idea about the platform. Qualcomm highlights the 7nm manufacturing process, multi-day battery life, and multi-gigabit […]

microSD Express Cards to Deliver SSD Performance

Last Summer the SD association released SD 7.0 specification with two key new features: SD Express adding PCIe and NVMe interfaces to the legacy SD card interface for transfer rates of up to 985MB/s, and SDUC (SD Ultra Capacity) card allowing capacities of up to 128 TB. This all looks great, but while the latter was available for both micro SD cards and full size SD cards, microSD cards could not benefit from the new high speed interfaces part of SD Express specification. SD 7.1 specification fixes that, as the SD association has now added microSD Express card which will also be able to reach up to 985MB/s (in theory) thanks to PCIe/NVMe interfaces, so we’ll be able to get sort of “removable SSDs” for smartphone and other devices that compatible with SD Express. As illustrated above microSD Express cards will be available in various capacities as microSDHC Express, microSDXC […]
