Getting Started with Espruino & JavaScript on ESP32 with ESPino32 Board

Venus Supply Co., Ltd, better known as ThaiEasyElec, is a company based in Thailand, selling embedded systems and development board, as well as providing development services based in Thailand. The company sent me their latest board called ESPino32 powered by Espressif ESP-WROOM-32 WiFi and Bluetooth module for evaluation. While the board is supported in Arduino-esp32, I’ve already tested Arduino with ESP32-Bit module & ESP32-T board, so after checking out the hardware, I’ll load it with something different: Espruino, a firmware allowing for JavaScript programming over the serial console, or a Web based IDE. ESPino32 Unboxing and Soldering The board shipped with four female headers, and I/O stickers. The board includes ESP-WROOM-32, exposes I/Os through four 10-pin headers, features CP2104 chip for serial to USB debugging via micro USB port, two buttons (reset and program), a user LED connected to IO16, and a jumper to select between regulated power supply (micro […]

The Internet of Bridges? Connected and Solar Powered Systems for Rainfall and Stream Water Level Monitoring

We often drive on a bridge fitted with some solar powered equipment, and recently they added a solar powered camera pointing towards the river, so I became curious and decided it would be fun to have a look, and find out what it was all about. There are now 3 solar powered and connected systems. The first system has a larger solar panel connected to a Bosch camera, and a white box… The sticker on the box gives away the purpose of the system: “National Disaster Warning Center” If we look the other side of the system we’ll see an antenna (for 3G/LTE?) as well as a light pointing down to a scale to measure the water level… Probably not the most cost effective way of checking out the level, but it works, and they should have a live feed in case something goes very wrong, and it might be […]

Linaro Connect 2016 Bangkok Schedule – March 7-11, 2016

Linaro Connect Bangkok (BKK16) will take place on March  7 – 11, 2016, and the schedule is now available for the 5-day event with keynotes and sessions. Whether you’re going to attend or not, it’s always interesting to check the schedule to find out what’s going on in terms of ARM Linux development. The five days will focus on work by different Linaro groups, but really sessions are mixed for any given day, and I’ve created a virtual schedule for each day with available information, as Linaro has become a little more closed to the outside than when it was launched a few years ago. Monday 7 – LITE (Linaro IoT & Embedded Group) 1400 – 14:50 – Evolution of the Reference Software Platform Project The Reference Software Platform lead project was introduced in Linaro Connect San Francisco 2015, and since then it evolved and matured with the completion of […]

TESPA Hawk IoT Board Combines ESP8266 with STM32 MCU in an Arduino Nano Form Factor (Crowdfunding)

TESPA Hawk is an IoT board designed by three companies based in Thailand and Singapore: Deaware delivers the embedded software for the board, Gravitech handles hardware design and manufacturing, and MakerAsia provides the IoT cloud platform. At first glance, it looks like yet another board based on the popular ESP8266 WiSoC, but it also includes an STM32 micro-controller, and its pinout is the same as Arduino Nano. There are also various add-on boards (WINGs) to easily and quickly prototype IoT projects. TESPA Hawk specifications: WiSoC – Espressif ESP8266 @ 80MHz with 8MB Flash MCU – ST Micro STM32F042G6 ARM Cortex-M0 MCU @ 48MHz with 32KByte Flash, 6KB SRAM Connectivity – WiFI 802.11 b/g/n/ with on-board antenna and u.FL socket for external antenna USB – micro USB port for power and programming Expansion – 2x 16-pin headers (mostly) compatible Arduino Nano pinout including 5-channel full range 3.3V ADC (4x 12-bit, 1x 10-bit), […]

A Quick Look at SAMART Strong Black “Free” DVB-T2 Receiver in Thailand

Thai government has made digital television a priority, so they’ve launched a program to give a 690 Baht voucher ($21) to all households in Thailand. The voucher is send by registered mail to your home, and delivery has to be signed by a Thai person. Then you can go to a shop equipped with a Thai ID card and house registration book copy, present this voucher, and get a free (except for tax payers of course) DVB-T2 receiver, or use it to buy something a more advanced set-top box or digital TV package with 690 Baht discount. We decided to get a free DVB-T2 receiver, and ended up with a box called SAMART Strong Black supporting SD and 1080p video streams over DVB-T2, EPG (Electronic Program Guide), and with a USB port to connect devices for recording programs or time-shifting. SAMART is a Thai company whose name means “can” (formal) […]

Unboxing of HD18T Android Media Player with DVB-T2 Tuner

Shenzhen Tomato has sent me a sample of HD18T, an Android TV box powered by Amlogic AML8726-MX dual core processor that features a DVB-T2 tuner with In and Out antenna connectors. This is quite timely as Digital TV in Thailand has just started on April 1st of this year. Today, I’ll go through the specs, unbox the device, and show some pictures of the box, the board and DVB-T2 tuner. HD18T Specifications The device enclosure and specifications are very similar to EM6-S2 DVB-S2 Android TV box I covered previously, expect the DVB-S2 tuner is replaced by a DVB-T2 tuner: SoC – AMLogic AML8726-MX dual cortex A9 @ 1.5 GHz + Mali-400MP2 GPU System Memory – 1GB DDR3 RAM Storage – 8GB NAND FLASH + SD card reader Video & Audio Output – HDMI 1.4, AV Audio Output – HDMI, AV, and optical S/PDIF.  Dolby TrueHD and DTS HD pass-through.
