Another ESP32 based weather station that retrieves weather data from OpenWeatherMap via WiFi and display the infor on a 3.2″ Nextion Touch Display. It also uses the BME280 sensor for measuring weather data locally. The display is refreshed every two seconds and the weather forecast is made every hour.

We have added a new IoT product to our Tindie store. It is a rapid prototyping and development board for the powerful ESP32 WiFi/BLE module. It is targeted toward rapid development of a wide variety of IoT applications, supporting both WiFi and Bluetooth connectivities. The development board breaks out all the module’s pins to 0.1″ headers and provides a CP2102 USB-TTL serial adapter on board for easy programming. The board also features on-board power supply regulator and an integrated LiPo Battery Charger. ESP-WROOM-32 is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor

A systematic arrangement of electrical components defined by pathways, signal traces, and conductive paths is called a Printed Circuit Board. If as a beginner you question, ‘what’s a PCB?’, then for simpler understanding, you can look at a PCB this way. Functionally speaking, the PCB offers mechanical support to electrical connections arranged in a logical manner with the help of pads, tracks, and other features. You can find the best PCBs at a cheap PCB manufacturer such as Elecrow. Types of PCB PCBs can be categorized as follows: Single Sided PCBs Multilayer PCBs Double Sided PCBs Flex PCBs Rigid PCBs Rigid-Flex

Texas Instruments (TI) is a well-known US-based semiconductor manufacturer. TI is perhaps best known to many as the manufacturer of some of the fanciest scientific calculators in the market. Of the long list of electronic devices produced by TI, microcontrollers are on the top. TI manufactures some of the coolest and advanced microcontrollers of the market today. There are several categories of micros from TI. These include general purpose low power MCUs which mainly comprise of MSP430s, ARMs like TM4Cs, MSP432s, etc, micros for wireless communications like CC2xxx series, ARM + DSP micros, DSP-specialized micros like the TMS32xxx series and
