Wemos LOLIN D32 Pro ESP32 Board Supports TFT Displays, Comes with a micro SD Card Slot

Wemos LOLIN D32 Pro

Wemos is popular for their low cost WiFi board based on Espressif SoCs. Their most popular board is ESP8266 based Wemos D1 mini  thanks to its compact form factor, low price ($5 shipped), and available add-on boards. But they’ve also launched some ESP32 in the last year or so with development boards such as Wemos LOLIN32 Lite. Their latest ESP32 board – LOLIN D32 Pro v2.00 – features ESP32-WROVER module, and beside exposing I/Os via breadboard compatible headers, also offers a micro SD card slot, a TFT display connector, and an I2C header. LOLIN D32 Pro specifications: Wireless module – ESP32-WROVER 802.11 b/g/n WiFi + Bluetooth 4.1 LE module with 4MB Flash, 4MB PSRAM Storage – micro SD card slot supporting SPI mode Display I/F – TFT display connector USB – 1x micro USB port for programming and power Expansion 2x 16-pin headers with GPIOs, SPI, I2C, UART, ADC, DAC, […]

ASUS Announces 802.11ax WiFi Routers at Computex 2018

802.11ax is a new WiFi standard offering better performance, especially in high-density scenario, where average per usage bandwidth may be improved by up to 4 times, so city dwellers should benefit the most. Last year, we started to see 802.11ax compliant chips from Broadcom, Marvell, Qualcomm, and others, so it should come as no surprise that some of first 802.11ax WiFi routers are launched this year. ASUS introduced two 802.11ax WiFi routers at Computex 2018 with ROG Rapture GT-AX11000 tri-band 802.11ax router, RT-AX88U dual band 802.11ax router , and the AX6100 WiFi System for mesh networking. ROG Rapture GT-AX11000 The ROG Rapture GT-AX11000 is a high-end router with a peak aggregate throughput of about 11000 Mbps. Specifications: Processor – Quad core processor @ 1.8 GHz System Memory – 1 GB RAM Storage – 256 MB flash Connectivity WiFi 802.11a/b/g/n/ac/ax,  IPv4, IPv6 Tx/Rx – 2.4 GHz 4×4, 5 GHz-1 4×4,  5 […]

ESP8266 based ANAVI Light Controller can be Programmed with Home Assistant or the Arduino IDE (Crowdfunding)

ANAVI Technology previously launched a Light pHAT allowing for RGB Light strip connection to Raspberry Pi boards, and during my review of ANAVI Light pHAT with Raspberry Pi 2, it did the job, but if that’s all you want to do, the  Raspberry Pi board is clearly oversized & overpowered for the job. So Leon ANAVI got back to the drawing board and designed a similar open source hardware board – called ANAVI Light Controller – with an built-in ESP8266 module that removes the need for a fully fledged Linux board. ANAVI Light Controller specifications: Wireless Module – ESP8266MOD module based on ESP8266 Tensilica L106 32-bit processor Connectivity – WiFi 802.11 b/g/n Expansion Terminal block for 12 V RGB LED strip 3x I2C headers for sensors Debugging – UART header Misc – Button Power Supply – 12 V via power barrel jack Dimensions – 75 mm x 40 mm Certification […]

Wi-Fi EasyMesh is a Standard for WiFi Mesh Networking

WiFi EasyMesh

It’s been possible for add multiple WiFi routers and/or WiFi repeaters in order to provide good coverage in a house / building for years, so this required some manual configuration. So in recent years, companies came up with WiFi mesh networking solutions that do very much the same, but are easier to setup, and – as I understand it – mostly plug-and-play. Some examples are Google WiFi router or eeRo Pro WiFi system,  but apparently so far every company would do their own proprietary WiFi mesh implementation, so you would not be able to mix brands for such features. That’s why the WiFi Alliance worked on, and now announced Wi-Fi EasyMesh, an industry standard  for “simple to use, self-organizing, smart Wi-Fi networks”. Key benefits listed by the organization: Flexible design – Allows for best placement of multiple APs providing extended coverage Easy setup – Delivers automatic device on-boarding and configuration […]
