Sell LoLin V3 NodeMcu ESP8266 IoT Lua WIFI / NodeMcu Base V0.1 Board Development Board best price

The NodeMcu is an open-source wifi development kit that speed up your prototyping project especially for IOT purpose. Using a few LUA Script line, it can be programmed using Arduino IDE, which can dramatically help novice learner to reduce redundant work for controlling their hardwares. The Development board is based on popular low cost wifi cheap ESP8266, version 12, integrates with GPIOs, PWM, II2, 1-Wire and ADC module packed in one board. This board comes together with a USB to TTL converter chips, CH340G which allows user to program the board or communicate via UART protocols directly using a microusb cable. There are two ways to power up NodeMcu, via Vin pins or USB cable. Vin pins are connected to a AMS117-3.3V regulator, so the input voltage is between 4.5V to 9V. Since ESP8266 chips are still operating at 3.3VDC level, do not connect any voltages more than 3.3V to the rest of the pin except Vin. We strongly recommend a voltage divider or logic level shifter to communicate your I/O device safely.
