ESP32-PICO-V3-ZERO-DevKit targets Amazon Alexa Connect Kit (ACK) development

Last summer, Espressif and Amazon jointly announced the ESP32-PICO-V3-ZERO Alexa Connect Kit module providing out-of-box connectivity to ACK (Alexa Connect Kit) cloud services, support for features such as Alexa control, “Frustration-Free Setup” and Amazon Dash replenishment for connected devices. At the time, the module was still at the developer preview stage, and you had to create your own carrier board for the module. But now development has been easier with the companies launching ESP32-PICO-V3-ZERO-DevKit compatible with Arduino Zero development board. ESP32-PICO-V3-ZERO-DevKit specifications: Wireless module – Espressif Systems ESP32-PICO-V3-ZERO with ESP32-PICO-V3 System-in-Package (SiP) based on ESP32-V3 dual-core Xtensa LX6 WiFI and Bluetooth SoC, a 4 MB SPI flash, a crystal oscillator, filter capacitors, and an RF matching network. Expansion – Arduino Zero compatible pass-through headers Debugging – 1x micro-USB port Misc – Power & Status LEDs, Reset button, jumpers to route specific signals to the headers, DSN (Device Serial Number – […]

Espressif and Amazon Introduce ESP32-PICO-V3-ZERO Alexa Connect Kit Module

Espressif Systems & Amazon have recently announced ESP32-PICO-V3-ZERO Alexa Connect Kit (ACK) module providing out-of-box connectivity to ACK cloud services, support for features such as Alexa control, “Frustration-Free Setup” and Amazon Dash replenishment for connected devices. The tiny (23 x 16 x 2.3mm) module is based on the company’s ESP32-PICO-V3 System-in-Package (SiP) based on ESP32-V3 dual-core Xtensa LX6 WiFI and Bluetooth SoC, a 4 MB SPI flash, a crystal oscillator, filter capacitors, and an RF matching network. The module supports 2.4 GHz 802.11 b/g/n WiFi, Bluetooth, and Bluetooth Low Energy connectivity and comes with a PCB antenna and a u.FL connector to plug in an external antenna [Update: That should be an RF test connector instead, see comments]. ESP32-PICO-V3-ZERO module interfaces to a host MCU through a UART interface, and to speed-up time-to-market the module comes pre-certified for regulatory certifications such as FCC, CE, SRRC, IC, and RCM. The module […]

Sonoff 4CHR3 is a 4-gang Wi-Fi Smart Switch with optional RF433 Connectivity

ITEAD Studio introduced Sonoff 4CH 4-gang WiFi + RF switch in 2017 with a DIN rail enclosure, compatible with eWelink Android/iOS app, and offering three modes of operations selectable from physical switches on the unit: Self-locking mode – Each relay can be turn on and off independently. Interlock mode – Only one of the relay can be turned on at a given time. For example if R1 is on, and your press R2 to turn it on, R1 will automatically turn off Inching mode – A button press on the unit, mobile app, or RF/WiFi remote control will turn on the relay for X seconds as defined by K6 “delay” switch within a 0.5 to 3600 seconds range. The company has now launched the similar SONOFF 4CHR3 4-gang WiFi switch and 4CHPROR3 model that adds 433MHz connectivity, with the main difference again the previous generation being the ability to select […]

$7 Sonoff D1 Smart Dimmer Switch Supports Mobile App, RF433 Remote, and Voice Assistants

Sonoff D1 Smart Dimmer Switch & RF433 Remote

ITEAD Studio Sonoff is a family of WiFi or/and 433 MHz RF connected smart home switches, sockets, light bulbs or other products for home automation. They are usually based on ESP8266 WiSoC and while the pre-loaded firmware works with eWelink Android/iOS app and popular voice assistant, it’s also possible to load open-source firmware such as Sonoff-Tasmota or ESPurna to add MQTT and other protocols in order to integrate those with home automation solution such as Domoticz, or something control those from your web browser. The company has now launched another Sonoff device, namely Sonoff D1 smart dimmer switch which – as its name implies – will allow you to dim incandescent and dimmable LED lights. Sonoff D1 smart dimmer switch specifications: Connectivity – RF433 and 802.11b/g/n WiFi 4 Max Current – 1A Max Power – 400W for Incandescent lamp, and 150W for LED light Power Supply – 110V-230V AC input […]

Sonoff S55 Waterproof WiFi Smart Sockets are Offered in Six Regional Variants

When WiFi smart sockets (aka smart plugs) started to appear a few years ago, they were often only available with either US or China plugs, and users from Europe, UK or other locales may have had to use an adapter instead. Since then, products that ship with multiple versions such as Sonoff S26 or Orvibo Wiwo S20 have launched in order to cater to more people around the world. ITEAD has now launched another WiFi smart socket, namely Sonoff S55, that’s designed to work outdoors thanks to IP55 ingress protection rating, and is offered in six different variants for Australia, Germany, France, the United States, South Africa, and the United Kingdom. Sonoff S55 specifications: Input/Output S55TPI(AU) – AC 100-240V 50/60Hz 10A Max S55TPF(DE) – AC 100-240V 50/60Hz 16A Max S55TPE(FR) – AC 100-240V 50/60Hz 16A Max S55TPB(US) – AC 125V 50/60Hz 10A Max S55TPD(ZA)- AC 100-240V 50/60Hz 10A Max S55TPG(UK) […]
