Espressif Unveils ESP32-S2-MINI Modules, ESP32-S3 and ESP32-C3 SoC’s Coming Soon

Espressif Systems has unveiled two new ESP32-S2 WiFi modules part of the new MINI series modules, namely ESP32-S2-MINI-1U with IPEX antenna, and ESP32-S2-MINI-1 with a PCB antenna. The press release also mentions upcoming ESP32-S3 and ESP32-C3 processors with few details. Let’s have a look. ESP32-S2-MINI modules Preliminary specifications: SoC – Espressif ESP32-S2FH4 single-core 32-bit LX7 microcontroller @ up to 240 MHz, RISC-V ultra-low-power co-processor, 320 kB SRAM, 128kB ROM, 2.4 GHz WiFi 4 connectivity, 4MB flash Antenna ESP32-S2-MINI-1 – PCB antenna ESP32-S2-MINI-1U – IPEX antenna connector Dimensions ESP32-S2-MINI-1 – 20 x 15.4 x mm ESP32-S2-MINI-1U – 15.4 x 15.4 x mm The company states the exact processor SKU used in the module is ESP32-S2FH4, but initially I could not find out it differed from ESP32-S2 since it has the same specs include a single-core processor, ULP core, up to 43 GPIOs, and USB-OTG support. It turns out the flash appears […]

xDrill Smart Power Drill Supports Intelligent Speed/Torque, Laser Measuring, Digital Leveling (Crowdfunding)

Many home appliances now have smart functions, and in my cases, I fail to see the added value, and I’m not sure why I’d want/need a connected refrigerator with a touchscreen display. So when I first saw somebody make a “smart” power drill with a small touchscreen display I laughed. But after having a closer look, Robbox xDrill smart power drill could actually be a very useful device saving you time and helping work better. The touchscreen is used for settings but also serves as a level tool to make sure the drill is aligned horizontally or at the angle of your choice, and you can also set the drilling depth. There are also two lasers that measure distances, so you don’t need to use a measuring tape and pencil anymore. xDrill key features and specifications: Built-in microcontroller with WiFi and Bluetooth connectivity (is that an ESP32 inside?) Display – […]

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 Zigbee Bridge Now Supports Tasmota Firmware, Home Assistant, Zigbee2Tasmota

Sonoff Zigbee Bridge & Tasomota Home Assistant

Sonoff ZBBridge (aka Sonoff Zigbee Bridge) WiFi to Zigbee gateway was launched a few months ago for $16.90 plus shipping, and it’s now also listed on Banggood for $17.99 shipped. It allows users to control Zigbee devices connected to the gateway using the eWelink mobile app used with other Sonoff devices. But many people like to run Tasmota firmware on their Sonoff devices since it’s open-source and provided more flexibility such as integration with Home Assitant or Domoticz. There was already support for Zigbee in Tasmota at the time but only for Texas Instruments SimpleLink CC253x Zigbee MCU’s, and Sonoff ZBBridge is made of an ESP8266 WiSoC and a Silicon Labs EFR32MG21 Gecko Series 2 Cortex-M33 Zigbee microcontroller. So I just suspected that eventually, Sonoff Zigbee Bridge could support Tasmota open-source firmware but that would take some time… It took about four months. Not too bad. It started in the […]
