Sonoff POW and Sonoff TH16 WiFi Relays Review – Part 1: The Hardware

Sonoff TH16 is a WiFi 16A relay that can take external sensors via a 2.5mm jack, while Sonoff Pow is a WiFi relay capable of measuring power consumption. Both have been designed by ITEAD Studio, and feature Espressif ESP8266 WiSoC. The company sent me both items for review, and I’ll start by checking out the hardware a little more closely than what is possible during the product announcement. I received Sonoff TH16 together with Sonoff AM2301 temperature and humidity sensor, which I’ll use to use to control an outdoor water pump and gather temperature and humidity data, as well as two Sonoff POW relays,which I plan to use to measure power consumption in my office, both from the power outlets and my aircon. All three WiFi relays support 3500 Watts, and 85 to 250V input. The packages have three QR codes for eWeLink iOS app, the Android app (coolkit.apk), and […]

RabbitMax Flex IoT Board for Raspberry Pi Supporting up to Five I2C Sensors Launched on Indiegogo for 20 Euros and Up

RabbitMax Flex is an add-on board, compatible with HAT specifications, for Raspberry Pi 2 /3 boards and other Raspberry Pi models with a 40-pin GPIO header. It includes headers for up to 5 I2C sensors, as well as an RGB LED, a buzzer, a relay, a button, infrared receiver and transmitter, and an optional LCD display, and as we’ve seen in my RabbitMax Flex getting started guide, a nice way to learning about hardware programming using either C or Python, or to used in home automation or IoT projects. The project has just been launched on Indiegogo. RabbitMax Flex specifications: Relay – Songle SRD-05VDC-SL-C supporting 125V/250VAC up to 10A, 30VDC up to 10A Storage – EEPROM with some system information for identification IR – IR LED, IR receiver Misc – Buzzer, Button, RGB LED Expansion Header for LCD character display + potentiometer for backlight adjustment 5x 4-pin headers for I2C […]

Getting Started with RabbitMax Flex IoT and Automation Hat for Raspberry Pi

At the beginning of the month I showed how to assemble RabbitMax Flex, a Raspberry Pi HAT compliant add-on board for Raspberry Pi boards with 40-pin header, that targets IoT and home automation project with its relay, IR transmitter and receiver, I2C headers for sensors, buzzer, RGB LED, and more.  Since I’ve already described the hardware, I’ve spend some time this week-end following the user’s guide to play around with the board using a Raspberry Pi 2 board, and try various features. The user’s manual explains that you need the latest version of Raspbian, but I’d not played with my Raspberry Pi 2 board for a while, so the kernel and firmware were quite old:

So the first thing I had to do was to upgrade Raspbian. There are basically two options to upgrade, either downloading and dumping the latest Raspbian firmware image to your micro SD card, and […]

Samsung Introduces $5 ARTIK 0 and $50 ARTIK 7 Smart IoT Module Families

Samsung unveiled ARTIK 1, 3 and 5 boards for the Internet of Things in 2015, and started to sell them, together with development with WiFi, BLE and Zigbee connectivity earlier this year. The Korean company has now announced two new family with ARTIK 0 modules powered by an ARM Cortex-M MCU and destined to be used in HVAC, lighting, industrial sensors, personal health monitoring and more, as well as ARTIK 7 family powered by an Octa-core Cortex A53 processor, and targeting IoT gateways. ARTIK 0 Family ARTIK 0 family is now comprised for ARTIK 020 with Bluetooth, and ARTIK 030 for applications requiring Thread and/or Zigbee. Beside the different radios, both modules share the same key features: MCU – ARM Cortex-M4 up to 40 MHz with Floating Point Unit, 256KB flash, 32 KB SRAM, advanced hardware cryptographic engine with support for AES-128/-256, ECC, SHA-1, SHA-256, and a Random Number Generator […]

Pine64 PADI IoT Stamp WiFi IoT Kit Review – Part 1: Hardware, Debuggers, and Soldering

Back in September, Pine64 unveiled their $2 PADI IoT Stamp based on Realtek RTL8710 ARM Cortex M3 WiFi SoC aiming to compete with Expressif ESP8266 solutions.  The company has now sent me their complete kit for review, which beside the module itself includes a breakout board kit, and some hardware debug tools. In the first part of the review, I’ll check out the hardware, and solder the kit. I received a package with four antistatic bags. From top left to bottom right, we have PADI IoT Stamp, JLINK-OB debugger based on an STM32 MCU with some jumper wires (aka Dupont cables) for SWD signals, and a USB cable to your computer in order to flash the firmware or do some bare metal programming, a breakout board kit including two headers, a RED LED, and a resistor, and finally a USB to Serial board based on CH340G with 4 jumper wires […]
