The controllers are easy to program by using the CP2102-USB interface without having to press the flash and reset buttons before each flash operation. | The development board has integrating GPIO, PWM, IIC, 1-Wire and ADC all in one board. Support smart link smart networking. | The fast and affordable technology for WiFi. Make your development the fastest way combined with firmware for NodeMcu. | Modern, state-of-the-art LUA technology. It is an integrated unit with all available resources on board. It's very easy for Arduino projects or any development board with I / O pins. | Modern Internet development tools can use the built-in API to instantly put your idea on the fast track.

IMPORTANT: Only compatible with 38 pins Narrow and No Mounting Hole Version esp32 development board, ref asin: B07QCP2451. Not applicable to other versions. | GPIO 1 INTO 2: This breakout board can expand one GPIO pin of esp32 development board to two, which is convenient for users to reuse all pins in smart home projects. Nice breadboard alternative. | 2 TYPE CONNECTIONS: Pin Header & Screw Terminal. Just select them according to your purpose. | DOUBLE-LAYER PCB: The expansion board is a double-layer board. One pin is wired on both sides. Therefore, the circuit is stable and highly reliable, and there will be no poor circuit contact and unstable signal transmission. | UPDATED VERSION: Compared with the previous version, the board of this version has been soldered completely. No need to solder parts by yourself, which is very convenient to use.

This module is safe, reliable, and scalable to a variety of applications. | The module has 38 pins and has more features than a 30-pin module. Narrower width, compatible with breadboard | Support Lua program, easy to develop. Support of three modes: AP, STA and AP + STA. | This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips ESP-WROOM-32, as well as the 40nm low-power technology. | Technical Support: Our PDF tutorial is available on this page.
