ESP32-WROOM-32D / ESP32-WROOM-32U WiFi & Bluetooth Modules Deliver Better RF Performance

ESP-WROOM-32 is likely the most popular ESP32 WiFi + Bluetooth module on the market, but a few months ago, Espressif Systems unveiled two variants named ESP32-WROOM-32D / ESP32-WROOM-32U, which are based on ESP32-D0WD (5x5mm package) instead of ESP32-D0WDQ6 (6x6mm package), and are said to offer better RF performance ESP32-WROOM-32D is the most similar to ESP-WROOM-32 since it also comes with a PCB antenna, while ESP32-WROOM-32U is much smaller as it relies on an external WiFi/Bluetooth antenna via a u.FL connector. Both new modules are pin-to-pin compatible with ESP-WROOM-32 Key features: CPU – Espressif ESP32-D0WD dual core Tensilica processor Storage – 32Mbit SPI flash Crystal – 40 MHz Connectivity – Wi-Fi 802.11 b/g/n up to 150 Mbps, Bluetooth 4.2 LE I/Os – 38- catellagated pin with I/Os + GND plane Antenna ESP32-WROOM-32D – on-board antenna ESP32-WROOM-32U – u.FL connector for external IPEX antenna Dimensions ESP32-WROOM-32D – 18 x 25.5 x 3.1 […]

Amazon FreeRTOS Released for NXP, Texas Instruments, STMicro, and (soon) Microchip Microcontrollers

FreeRTOS is an open source real-time operating system for microcontrollers released under an MIT license, and when it comes to adoption in embedded systems it’s right there near the top with embedded Linux according to Aspencore 2017 embedded markets study. For example, some Espressif SDKs for ESP8266 or ESP32 are based on FreeRTOS, and so is Mediatek LinkIt Development Platform for RTOS. The recently announced Amazon FreeRTOS (a:FreeRTOS) leverages the open source operating systems, and extends it with with libraries that enable local and AWS cloud connectivity, security, and soon over-the-air updates. a:FreeRTOS is free of charge, open source, and available today. In order to get started, you’ll have a choice of 4 hardware platforms: STMicro STM32L4 Discovery Kit IoT Node (B-L475E-IOT01A) powered by STM32L475 ARM Cortex-M4 MCU with 802.11 b/g/n WiFi, Bluetooth 4.1 LE, RF (868 / 915 MHz), and NFC connectivity, plenty of sensors NXP LPC54018 IoT module (OM40007) […]

Geolocation on ESP8266 without GPS Module, only WiFi

When I think about geolocation in I normally think about global navigation satellite systems such as GPS, GLONASS, Galileo, or Beidou, as well as IP geolocation, but the latter is highly inaccurate, and often only good for find out about the country, region, or city. But if you’ve ever been into your phone location settings, you’d know GPS is only one option, as it can also leverage cellular base stations and WiFi SSIDs, where the former working where there’s coverage, and the later in area with a high enough density of access points. Somehow, I had never thought about using such technology to find location with WiFi modules until Espressif Systems released an application note entitled “Geolocating with ESP8266“. This document describes how the ESP8266 module may be used to scan for nearby Wi-Fi access points and, then, use their SSID, RSSI and MAC address to obtain a potential fix […]
