WI-FI enabled
Ard–uino-like hardware IO
Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware.
Code like ard–uino, but interactively in Lua script.
Nodejs style network API
Event-driven API for network applicaitons, which faciliates developers writing code running on a 5mm*5mm sized MCU in Nodejs style.
Greatly speed up your IOT application developing process.
Introduction:
ESP32 is already integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters,
and power management module. The entire solution takes up the least amount of printed circuit board area.
This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips by TSMC 40nm low power technology,
power and RF properties best, which is safe, reliable, and scalable to a variety of applications.
Features:
High performance-price ratio
Small volume, easily embeded to other products
Strong function with support LWIP protocol, Freertos
Supporting three modes: AP, STA, and AP+STA
Supporting Lua program, easily to develop

Motor driven expansion board developed based on ESP-12E.
characteristic:
ESP12 DEV KIT development board expansion module;
Lead out all functional pins of ESP12 DEV KIT: SPI, UART, GPIO, AI and 3.3V power interface;
Two motor drives can be extended to directly drive two motors;
On board power switch;
L293D
Motor power supply range: 4.5V~36V;
Control power range: 4.5V~9V;
Separation of motor power supply and control power supply; In the experiment, VIN and VM can be short circuited through the combination of short circuit blocks, and the motor and control board can be powered at the same time.
Product specifications
Power input:
Motor power supply (VM): 4.5V~36V, which can be supplied separately;
Control power supply (VIN): 4.5V ~ 9V (10VMAX), which can be powered separately;
The module provides short circuit (short circuit VM and VIN), which can easily use one power supply (4.5V~9V) to drive and control the motor at the same time;
Logic working current Iss: ≤ 60mA (Vi=L), ≤ 22mA (Vi=H);
Operating current of driving part Io: ≤ 1.2A;
Dissipated power: 4W (T=90 ℃)
Control signal input level: high level: 2.3V ≤ VIH ≤ VIN; Low level: – 0.3V ≤ VIL ≤ 1.5V
Operating temperature: – 25 ℃~ + 125 ℃
Drive type: two-way high-power H-axle drive
ESP12E Dev Kit control ports: D1, D3 (motor A); D2, D4 (B motor)
Please note that
When inserting the ESP-12E module, please note that the antenna direction is consistent with that of the expansion board;
The short circuit module can supply power to the control board and motor at the same time.
