WiFiBoy32 is an ESP32 Portable Game Console and IoT Devkit

I’ve noticed that ever since Hardkernel launched their ODROID-GO “10th anniversary” portable game console based on ESP32 processor, most of the talk on IRC and social media is about this new toy, and people almost seem to have forgotten about the company’s Arm Linux boards 🙂 But recently, I’ve come across a somewhat similar ESP32 device called WiFiBoy32 that acts as both a portable game console and an IoT development kit. WiFIBoy32 specifications: Wireless module – ESP32-WROOM-32 wireless module with 802.11 b/g/n WiFi and Bluetooth 4.2 LE connectivity Display – 2.4″ 240×320 color SPI TFT LCD display Expansion – 2x 8-pin through holes with GPIOs, SPI, DAC, I2S,ADC, VP/VN, and power signals (3.3V, Vin, GND) Misc Top – 6x large gaming buttons, select and start push buttons, buzzer Bottom – PROG and RESET buttons, user LED USB – 1x micro USB port for power and programming (CP2102) Dimensions – 120 […]

Exen Proto Arduino Compatible Board is based on Microchip SAMD21 MCU (Crowdfunding)

Nerdonic launched Exen Mini last year as the world’s smallest 32-bit Arduino compatible board, and getting the smallest board possible is very good for some projects, but so not much for other as Exen Mini is limited to just 8 I/O pins. So the company made another larger board called Exen Proto based on the same Microchip SAMD21 Cortex M0+ microcontroller, but offering more I/Os. Exen Proto specifications with difference against Exen Mini highlighted in bold: MCU – Microchip SAMD21 Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB SRAM I/Os via 2x 12-pin 2.54mm pitch headers Up to 20x digital I/O Up to 19x PWM Up to 11x analog (ADC) up to 12-bit resolution 2x UART Up to 5x I2C 1x reset Limits – 3.3V, 7mA USB – 1x micro USB port Programming – Via micro USB port or SWD header Misc – Power LED, user LED, button […]

Kicad 5.0.0 Open Source EDA Suite Released

Once upon a time, your only options to design schematics and layout PCBs were to purchase expensive software like OrCAD, or install a pirated copy of the same software, which was the standard practice in the country were I worked (China). Later on, Cadsoft EAGLE made projects much more affordable since they had a free version for hobbyists albeit limited to smaller boards. But in recent years, a new open source project called KiCad changed the market again, as it is entirely free to use, the community can be involved, and there’s no limitation. The software has even become good enough for companies like Olimex to design their new boards. A week ago or so, the project hit a new milestone with the release of KiCad 5.0.0. Some notable new features include: Whole Project New libraries for symbols, footprints and 3D models based on KiCad Library Convention (KLC) New 3D […]

Faytech 15″ to 17″ Capacitive Touch PCs Ship with Ubuntu 16.04

Although many can support Ubuntu or other Linux distributions, most Intel based products ship with some version of Windows by default, and the end users may have to install Linux by themselves. While watching a Computex 2018 video on Armdevices.net, I found out FayTech, a company specializing in the design, development, manufacturing and marketing of touchscreen monitors & PCs, showed a 15″ Touch PC powered by an Intel Celeron J1900 “Bay Trail” processor and running Ubuntu 16.04 LTS. So I had a look on the company website, and the 15″ capacitive touch PC (FT15J1900W4G64GCAP) showcased in the video – embedded at the end of this article – comes with the following key features and specifications: SoC – Intel Celeron J1900 quad core processor @ 2.0 / 2.4 GHz with Intel HD Graphics; 10W TDP System Memory – 4GB DDR3L-1333 via 1x SO-DIMM slot, expandable to 8GB Storage – Industrial 64GB […]

$400 UGEE UG-2150 21.5″ Drawing Monitor Comes with a 2048-Level Pressure Sensitivity Pen

A few weeks ago, I wrote about a 7″ HDMI touchscreen display, and today when I first come across UGEE UG-2150 monitor, I thought I had found something similar but with a bigger display size. However, the 21.5″ monitor has a different target applications, and is specifically designed for drawing as it ships with a 2048-level pressure sensitivity stylus. UGEE UG-2150 monitor specifications: Display Resolution – 1920 x 1080 Colors – 16.7M Drawing / touch Pressure Sensitivity – 2048 levels Accuracy – 0.25 mm Report Rate – 220 reports/per second Response Time – 14ms Video Input – VGA, DVI, HDMI USB – 1x USB 2.0 port Power Supply – Yes… Dimensions Full device – 517x 321.89 x 30mm excluding the stand Active Area – 476.64 x 268.11mm The monitor ships with a P50S rechargeable pen, two pen holders, 8 different tips, a remove ring, a USB cable, a power adapter […]

Espruino Pixl.js is a Bluetooth LE Display Programmable with JavaScript, Compatible with Arduino Shields

Espruino is an open source firmware that allows you to control micro-controllers board with JavaScript, and used in hardware such as Wio LTE GPS tracker, some STM32 Cellular IoT Discovery Kits, and other platforms. I have actually tried Espruino and JavaScript programming in an ESP32 board myself, and it worked reasonably well. But Espruino developers also provide hardware platforms for Espruino, which – as one should expect – are normally better supported than other third-party board. One of their latest platforms is Espruino Pixl.js a Bluetooth smart display powered by Nordic Semi nRF52832 WiSoC. Espruino Pixl.js specifications: WiSoC – Nordic Semi nRF52832 Arm Cortex-M4 @ 64MHz with 64kB RAM, 512kB Flash, Bluetooth Low Energy connectivity (via a Raytac Corportation module) Display – 54mm diagonal, 128 x 64 sunlight readable monochrome display with white backlight Connectivity – Bluetooth LE and NFC tag I/Os 20x GPIO in Arduino footprint with PWM, SPI, […]

Extend VGA or HDMI Signals over “Ethernet” with VGA / HDMI Extender over Cat5/Cat6 Cables

A host computer or media player may not always be in the same room as its display(s), for example for digital signage where you may want to have several displays controlled by one computer in different rooms, or if you want to add a display to one of your room without necessarily adding another TV box or set-top box. We’ve already seen solution to extend the video signals over a few hundred meters using a HDMI powerline extender or wireless AV transmitted / receiver kit. The former is rather expensive (~$250) and the latter only works with composite. Today, I’ve come across other video extender solutions relying on Cat5/Cat6 “Ethernet” cables, first with an Ethernet to VGA extender kit that sells for $12.99 shipped on Banggood, but there are also Ethernet to HDMI solutions for around $25 to $40 offering a range of up to 120 meters over Ethernet. Both […]
