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, […]

Orange Pi 3G/4G Cellular IoT Development Kits with Touchscreen Display Launched for $35 and Up

Earlier this year, Shenzhen Xunlong introduced two new Orange Pi cellular IoT boards running Android – but no Linux distribution just yet – with Orange Pi 3G-IoT and Orange Pi 4G-IoT boards, with LTE bands suitable for Asia and most part of Europe, but not the US. But boards are quite cheap, the 4G-IoT model recently got Android 8.1 Oreo support, if you’d like a display with the board, you can now buy various kits with touchscreen display and in some sets a power supply as well for $34.80 and up plus shipping, or the displays only for $14.80 and up. Four kits have been launched so far: $34.80 Orange Pi 3G-IoT-A Set1 with Orange Pi 3G-IOT-A board powered by Mediatek MT6572 dual core Cortex A7 processor + 256MB RAM/512MB eMMC combo chip, and a 4.98″ TFT LCD touchscreen display (854 x 480) $39.80 Orange Pi 3G-IoT-B Set1 with Orange […]

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 […]

KidBright32 Board is Thailand’s BBC Micro:Bit Equivalent

BBC Micro:Bit board was first announced in July 2015. Designed for STEM education, the board was then offered to UK schools in March 2016, and a few months later UK store would start selling it worldwide. It’s now available pretty much anywhere, and you can likely find it in a local store or online. The Thai government must have seen this, and thought to themselves “If the British can do it, we can do it too!”, as the National Electronics and Computer Technology Center (NECTEC) part of Thailand’s Ministry of Science and Technology designed KidBright32 board and courses to teach STEM to Thai students. The board is based on Espressif Systems ESP32-WROOM-32 WiFI and Bluetooth module, and comes with large holes for power (5V/GND) and 6 digital inputs/outputs, smaller through holes for I2C and more I/Os, as well as an I2C header. We’ll also find some LEDs, two dot matrix […]

MatchX MatchBox LoRa Gateway Setup (for AS923) and Installation

At the end of last year, I received MatchX Matchbox LoRaWAN gateway, but only quickly checked out the hardware, as I was still unclear about regulations in South East Asia, and did not have any nodes to play with. Understanding Regulations and LoRaWAN Frequency Plans Since then, the government published some notifications about the 920-925 MHz band we are supposed to follow here. It’s in Thai language, and I can’t still read/understand it, but I got some translation help, and some key points include: paragraph 5 : for 920-925MHz non-RFID radio equipment (1) max EIRP not more than 4 watts (2) if EIRP < 50mW, no need for any license (3) if EIRP < 500mW, a license is required for importing, selling, and making your own equipment (4), and you must be in accordance with NBTC technical standard. (5) must not interfere with any licensed application. Interfering equipment must be […]

ROC-RK3328-CC Board Review, or the Case for Fast Storage and Adequate Power Supply

Firefly team from T-chip company has send me some of their Rockchip development boards, and we’ve already checked the provided boards and accessories, so today I’ll report my experience with one of the board: ROC-RK3328-CC also known as Renegade. I won’t test it with Android, since I have already reviewed RK3328 Android TV boxes such as Zidoo X7, and I’ve been told the team is hard at work with Android 8.1 SDK, so an Oreo image should be released in a few weeks/months. So I had initially planned to report my experience with one of the Linux images, then show how to install mainline Linux (currently 4.17) to the board, and reports what works. However, I encountered many issues, although likely not directly related to the board or its software support, so instead I’ll write about my experience getting started with the board, and list all the issues I had […]
