ESP8266 CP2102 NodeMCU LUA ESP-12E WIFI Serial Wireless Module.
Built-in Micro-USB, with flash and reset switches, easy to program.
Arduino compatible, works great with the latest Arduino IDE/Mongoose IoT/Micropython.

6 I/O Pins (2 are used for USB only if your program actively communicates over USB..
Support for the for Arduino IDE 1.0+ (OSX/Win/Linux)..
Power via USB External Source - 5v or 7-35v (automatic selection)..

Please NOTE: Open the Arduino IDE, you’ll need to click the “Tools”, then select the Board that corresponds to your Arduino. If you don't choose the correct development board type, it will cause the compilation to fail to transfer. So this is a place that needs special attention..
The keyestudio Leonardo is a microcontroller board based on the ATmega32u4，It has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button..
The Leonardo differs from other boards using separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor..
This allows the Leonardo to appear to a connected computer as a mouse and keyboard..
Has fcc and ce certification that they are made from environmentally friendly production technology and materials, made function,voltage, current testing before packaging.

ATSAMD21G18 ARM Cortex M0 processor(clocked at 48 MHz and at 3.3V logic, same one in the new Arduino Zero.
256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much).
Built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip.

The KEYESTUDIO Plus board can work like the Arduino Board but it is more powerful and has more pins.
The USB to Serial chip of this board is stable and compatible CP2102.
extend serial communication and I2C interface, 6 PWM and 6 analog ports.
special DC-DC design provides up to 5V 1.5A, can drive high-current devices like servo and motor.
The yellow text on black board makes identifying pinsets a breeze. FCC and CE is available.
How to use: Search for "keyestudio wiki KS0486" in Google Chrome to get the wiki online tutorial for this product. Technical supports are available at any time!.

Small Compatible with Arduino board. Includes Reset button, 9x 10-bit ADC pins. 12x Digital I/Os (5 are PWM capable).
Improved version of the SparkFun Pro Micro. ATmega32U4 running at 5V/16MHz Supported under Arduino IDE v1.0.1+.
On-Board USB-C connector for programming. AP2112 3.3V Voltage Regulator. PTH Pads w/ Castellated Edges.
Hardware Serial Connections. Includes UART (i.e. Rx and Tx), Qwiic Connector for I2C, and SPI. Has onboard Reset Button. Input maximum of 6V. Dimensions: 1.3in x 0.7in..
The AtMega32U4 can have the bootloader overwritten if not used properly. There is a way to fix the bootloader if needed and instructions are available online. USB drivers may be needed to be installed on a computer to communicate with the board..

ESP32-CAM WiFi + Bluetooth Module WiFi ESP32 CAM Development Board with Camera Module OV2640 2MPcompatible for Arduino, Support Image WiFi Upload and TF Card.
Bluetooth: Bluetooth 4.2 BR/EDR and BLE standard.
Camera WiFi + Bluetooth Module 4M PSRAM Dual-core 32-bit CPU Development Board with OV2640 2MP Camera Module + FT232RL FTDI USB to TTL Serial Converter + 20 pin Jumper Wire.
FTDI USB Serial Adapter comes with the FT232RL chip and uses both 3.3V and 5V operating voltage. Adapter Logic-level can be set via jumpers on the board, which makes simple to connect to your controller. USB power has over current protection, using 500MA self-restore fuse..
This module supports interfaces such as UART / SPI / I2C / PWM / ADC / DAC.

The board is a microcontroller board based on the CH340. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button..
This is compatible board with an Atmega328p and a CH340G serial converter, 100% Compatible with Arduino UNO R3..
This board has the following new features: 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes. Stronger RESET circuit..
Friendly: the board is easy to use for Arduino starter, It contains everything needed to support the microcontroller.
simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started..
We strive to put our hundred percent to meet your requirements and try our best to achieve your satisfaction!.
