4PCS ESP32 Development Board ESP-32S NodeMCU Board ESP-WROOM-32 WiFi Microcontroller 2.4GHz 2 in 1 Dual-Core WiFi + Bluetooth Processor Integrated Chip CP2102 Low Power Consumption ESP-32S

Dual core ESP-32 development board, 2.4GH z dual mode development board. There are two touch buttons, one is reset, the other is enable module to enter the halberd program mode. ^^ The module is ESP-WROOM-32 module, the peripheral uses the USB serial port chip CP2102 to expand the micro USB interface, which can be directly debugged by a USB connected computer, and the data transmission is fast and stable. ^^ ESP32 development board support lua program, easy to develop, support LWIP protocol, Freertos, three
modes: AP, STA and AP + STA. ^^ The module supports for NodeMCU and other development environments, which expands the range of its resources available and greatly improves the ease of learning and development. Of course, it can also be widely used in Internet of things occasions, such as home automation, wireless industrial control, wireless positioning system signal ^^ ESP32 is a safe, reliable, and scalable to a variety of applications, the user can cut off the power of the CPU and use the low-power coprocessor to continuously monitor the status of the peripherals or whether some of the analog values exceed the threshold.
