Freetronics Introduces an Arduino Shield for ESP8266 ESP-01 Wi-Fi Module

ESP8622 has drastically brought down the price of adding Wi-Fi to MCU boards such as Arduino UNO, but you need to add some cables, and take care of 3.3V to 5V conversion for the UART pins either with a divider made of 2 resistors, or a FET level shifter, and you may not be able to access all I/O of ESP8622 on the popular ESP-01 version of the module. For a neater solution, Freetronics had designed ESP-01 WiFi Module Shield that takes care of all these small issues. Key features of the shield: 3.3V regulator dedicated to the module Logic level shifters on TX/RX lines: compatible with both 3.3V and 5V Arduino models Selectable TX/RX pins: use D0/D1 for hardware serial, or D2 – D7 for software serial CH_PD pin on ESP-01 module pre-biased for correct operation mode Extra ESP-01 pins broken out for your own connections Prototyping area with […]

ZRRO Android Game Console Includes a Hover and Touch Controller (Crowdfunding)

Android games are fun to play… on smartphones and tablets, but if you want to play such games on a TV screen via an Android mini PC, it can become more problematic, as most of the games were designed for touchscreen, so you have to be prepare to juggle between input devices.. In my reviews, I have to play Candy Crush Saga with an air mouse, and I switch to a wireless gamepad for racing games such as Riptide GP2 or Beach Buggy Racing, while some games are simply not playable at all without touch emulation, unless you install a software remote such as Droidmote on your smartphone, and use the latter as a controller, which may not be ideal either. ZRRO, an Israeli company, came with a new package comprised of an Android game console (ZRRO Box), and a game controller (ZRRO Pad) featuring a hover and touch surface […]

Voltera V-One is a Low Cost PCB Printer and Solder Paste Dispenser (Crowdfunding)

The traditional hardware development cycle involve sending PCB Gerber files to a manufacturer, wait a few days (or weeks), get the boards back, find and fix bugs, send a new revision of the gerber files to the manufacturer and so on. This wastes a lot of time, so PCB printers capable of handline single and dual layer PCBs have started to see the light of the day, for example with BotFactory Squink. The latter can also do pick and place, but costs over $3,500. Luckily if you’d like something cheaper, Voltera V-One will do many of the same tasks, for but for only $1,500. Voltera V-One specifications: Minimum Trace Width – 8mil (~0.2mm) Minimum Passive Size – 0603 (0402 for solder paste) Minimum Pin-to-Pin Pitch – 0.8mm (0.5mm for solder paste) Resistance – >12 mOhm/sq @ 70um height Max Heated Bed Temperature – 250C Heated Bed Ramp Rate – ~2C/s […]

Power Consumption of Amlogic S812 and Rockchip RK3288 TV Boxes

The recent post comparing the power consumption of ODROID-C1 vs Raspberry Pi boards, as made me want to give another try at power consumption measurements. Regular reader already know I made a power measurement board and cables capable of hading different connectors (micro USB, mini USB, power barrels, etc..), but eventually it failed to deliver enough current to the boards for any meaning testing. But since I now have a better power supply, and multi-meter, it was worth another try, especially since I could draw some pretty charts. I decided to test the three most popular Chinese SoCs for mini PCs namely Amlogic S812 (4x Cortex A9), Rockchip RK3288 (4x Cortex A17), and Allwinner A80 (4x Cortex A15 + 4x Cortex A7) using respectively Eny M8S, Open Hour Chameleon, and A80 OptimusBoard. If you are paying attention, you must have noticed Allwinner A80 is not part of the title, that […]

HD18T Android DVB-T2 Receiver Mini Review

I’ve had HD18T Android TV box with a DVB-T2 tuner for several months, but I’ve only installed a roof antenna recently, so I’ve decided to give it another try since my indoor antenna did not pick-up any signal with that box. The set-top box is also known as EM6-T2 or HD18T2, and features Amlogic AML8726-MX dual Cortex A9 processor which has been used in numerous boxes in the past, so I will only focus on my experience with the DVB app in this mini review. If you want to use DVB-T2 go straight to the right and click on DVB app. Where you’ll then be greeted with a pop-up windowsasking if if you want to scan channels. You can do autoscan, manual scan (for one frequency), select the area (France/Taiwan/UK/Italy/Australia only), and enable/disable LCN (Logical Channel Numbering). At first I selected “Australia”, and the system did not find any channels, […]
