RTL8710 Ameba Arduino Development Board and Ameba Arduino v2.0.0 SDK Released

We’ve already seen a NodeMCU lookalike board called RTLDuino based on Realtek RTL8710AF ARM Cortex M3 WiSoC earlier this month, that can be programmed with a community supported Arduino port also called rtlduino via a JLink SWD debugger, but now Realtek has just launched Ameba RTL8710 Arduino board, and released Ameba Arduino v2.0.0 SDK which brings official Arduino support to RTL8710AF platforms. There appears to be two versions of the development kit: RTLDUINO_PRO_V1.0 and REALTEK-AMEBA_RTL8710_V2.0, but based on the user manual they seem to be identical, and as you can see from the above picture, it includes a baseboard and the aforementioned RTLDuino board. RTL8710 Ameba Arduino HDK key features: SoC – Realtek RTL8710AF ARM Cortex-M3 MCU @ 83 MHz with 802.11 b/g/n WiFi, hardware SSL engine connected to the baseboard via: RTLDuino board through female header B&T RTL-00 module soldered on module footprint USB – 2x micro USB ports, […]

Getting Started with Onion Omega2+ LEDE WiFi IoT Board and Expansion Dock

Onion Omega2 LEDE (OpenWrt fork) WiFi board is powered by Mediatek MT7688 MIPS SoC, targets IoT projects, and sells for as low as $5. There are actually two versions: Omega2 with 64MB RAM, 16MB flash, and Omega2+ with 128MB RAM, 32MB flash and a micro SD slot. Onion sent me the latter for review, together with an expansion dock that allows powering up the board though USB , and adds a USB host port, an RGB LED, buttons, and access to GPIO via a female header. In this quick start guide, I’ll start by taking some unboxing pictures, and then report my experience following the documentation to configure the board, blink the RGB LED, and control a LED on a breadboard using a GPIO from the header. Onion Omega2+ Unboxing I received the two boards in their respective package, and which are both stored in anti-static bags. Let’s check Onion […]

$10 RTLDuino is an Arduino Compatible WiFi IoT Board based on Realtek RTL8710AF WiSoC

Last summer, we discovered a cheap RTL8710AF WiFi module with many of the same function as ESP8266, but with an ARM Cortex M3 core instead. The only problem is that it was not quite as easy to play with as ESP8266 boards, as at the time I started by playing with AT commands with B&T RTL00 RTL8710AF module, and later on, I got a more convenient PADI IoT Stamp with breakout board, but if you wanted to change the firmware you had to play with the SDK and a J-Link SWD debugger. Realtek RTL8710AF did not offer the convenience of Arduino IDE program like its big brother “RTL8195AM” from the same Ameba family. I know mbed is being worked on, but in the meantime things have changed for the better, as kissste informed me that RtlDuino implementation added Arduino support to RTL8710AF and RTL8711AM modules, and an NodeMCU-like board with […]

ESP32-WROVER-KIT Devkit Supports Espressif ESP32 Modules, Includes a 3.2″ LCD Display

Yesterday Olimex wrote a blog post informing us that ESP32-CoreBoard was back in stock, one the many ESP32 boards launched late this year, but still hard to get. The company also mentioned they’d have limited quantity of the new ESP32-WROVER with JTAG and LCD display together with the picture below. ESP32 is quite more powerful than ESP8266 so it makes sense to have an ESP32 development kit with an LCD display. A quick DuckDuckGo search led me to ESP-WROVER-KIT Getting Started Guide, where we can find more details including the overall specifications: Compatible with ESP-WROOM-32 and ESP32-WROVER modules based on ESP32 dual core Tensilica L108 processor clocked at up to 240 MHz with WiFi and Bluetooth LE connectivity Storage – Micro SD slot Display – 3.2″ LCD display connected via SPI USB – 1x micro USB port Expansion 8-pin UART header 6-pin SPI header 48-pin header for I/Os and camera […]

ESP8266 based Wireless Air Quality & Environmental Monitors Teardown – Sonoff SC and vThings CO2 Monitor

The mailman delivered two parcels today, and interestingly enough they have a similar functionality measuring air quality and environmental data such as temperature. The first package was ITEAD Studio Sonoff SC environmental sensor with ESP8266, an Atmel MCU, DHT11 temperature & humidity sensor, a dust detector, a light sensor, and a microphone, while the second was v-Air Monitor vThings CO2 monitor v3 also based on ESP8266 with a CO2 sensor and other optional sensors. I’ll test both with their stock firmware later on, but today I’ll have a look at the hardware design. v-Air Monitor vThings CO2 monitor specifications While I’ve already written about Sonoff SC, it’s the first time I cover v.Air Monitor products, so let’s start with the specifications of vThings CO2 Monitor v3: SoC – Espressif ESP8266 WiSoC Connectivity 802.11 b/g/n WiFi Optional RF315 / 433 MHz RF module Sensors CO2 Sensor (one of them) CM1106 NDIR […]

YokaTV KB2 Review – Amlogic S912 TV Box with 32 GB Flash

CNXSoft: This is another review by Karl about Amlogic S912 based YokaTV KB2 TV box. Introduction Today we will be looking at Videostrong YokaTV KB2. Below are the specs from Videostrong website. This is my first S912 device so I had high expectation. I have been using it for quite some time now with no major issues. I received approximately 6 OTA updates since I started testing and some welcome updates have come. Build When I receive a box first thing I do is take it apart and check out the inside. I was excited when I found out it had 32 gig of storage. It is not too common. Then when I opened the box I was really happy to see an antenna that wasn’t soldered on. Makes it easy to add a different one. +1 for KB2. Then I noticed the heat sink. It seemed a little small. […]
