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 […]

RFCat N32 Long Range nRF52832 Bluetooth Board Delivers 30x the Transmission Power with an Amplifier

Bluetooth 5.0 has two main new features: high speed (2Mbps) and long-range. But as we’ve seen in our nRF52840 vs nRF52832 vs nRF52810 comparison is that only nRF52840 supports Bluetooth 5.x long range. Bluetooth 5 long range is achieved with two new lower bit rates of 500 kbps and 125 kbps. So what do you do if you’d like a longer range and keep using the higher bit rates? You add a power amplifier and LNA to your board, and that’s exactly what Nikolaj (RFCat) did with RFCat N32 board based on Nordic Semi nRF52832 wireless SoC. RFCat N32 board specifications: Wireless module – Meshtek-H52 Smart Mesh Module with integrated PCB antenna based on Nordic Semi nRF52832 Arm Cortex-M4F Bluetooth 5-ready SoC (See datasheet) Skyworks RFX2401C PA &LNA with 18.9dBm TX gain and 11dBm RX gain USB – 1x USB-C port for power, programming and debugging via CP2102N USB to […]

Aegis Secure WiFi Smart Deadbolt Works with Android/iOS Phones (Crowdfunding)

We previously wrote about smart lock systems that allow you to open your door with the help of your smartphone. Products covered including Xiaomi Sherlock M1 that only works with specific doors/locks, and K1 smart lock box that stores your keys in a rugged box meaning it works with all door mechanisms, but it does not seem particularly secure to me. BOSMA Aegis Bluetooth & WiFi smart deadbolt looks to potentially a more secure solution as it should work with any door, and complements your main lock which you may want to use when you are not at home for longer periods of time. Aegis smart deadbolt specifications: Connectivity – Built-in Bluetooth; WiFi via a WiFi connector shipped with Aegis Voice Assitant Integration – Google Home and Amazon Alexa Optional BOSMA Sentry smart doorbell with Storage – Up to 128GB via MicroSD card slot; cloud storage Video – 1080p video […]
