The popular NodeMCU ESP32 boards are great for IoT Applications but cannot be powered from batteries directly. This board is an ESP32 development board but with an added option of running the board from a battery powered.
This latest ESP32 IoT Development Board includes an onboard WiFi and BLE Bluetooth Module along with support for a LiPo battery. Perfect for developing IoT and BLE Projects. This board can be powered from a single Lithium Ion Battery. It also has an inbuilt battery charger and the battery can be charged through the USB Port. Compared to the standard NodeMCU ESP32 and other generic boards, this board is designed to consume low power during operation. It only consumes x ma during normal operation and x ma during sleep.
It uses the ESP32 module which is the successor to the hugely popular ESP8266 Module. This board is great to develop WiFi and BLE projects and applications that have to be powered by a lithium ion battery. You can directly use this development board in your battery powered project, without having to design seperate external circuits for battery and charging. It fits directly onto a breadboard and let you connect sensors, relays, and other external modules through its standard input output pins.
The ESP32 Development Board contains all the external circuits required to use the ESP32 IC, including the USB-UART bridge, reset- and boot-mode buttons, LDO regulator and a micro-USB connector. Every important GPIO is available to the developer. Everything necessary to program, run and develop on the ESP32 chip is included onboard. In addition to the WiFi/BLE SoC, the Thing includes an CH340, which converts USB to serial, and allows your computer to program and communicate with the microcontroller.
