The D1 R2 is a WiFi capable ESP8266EX based development board in the form of the common Arduino UNO board format. This board is compatible with the Arduino IDE and with NodeMCU. The D1 R2 also features an on-board switching power supply which allows you to power the board from a power supply up to 12V.
*Note: The D1 R2 is a 3.3V device. If you connect it to 5V digital sensors or devices you will need a logic level converter.
This Arduino compatible motor Driver shield is a full-featured products that it can be used to drive 4 DC motors or two 4-wire stepper and two 5V 'hobby' servo. It drive the DC motor and stepper with the L293D, and it drive the servo with Arduino's pin9 and pin10.
The board can not only receive MEGA seamless plug controller, directly soldered to the above components to complete a variety of prototype circuit, you can paste Mini bread board, through the 7-color jumper to complete a variety of circuit experiment , board integrated power indicator and status lights, and reset buttons, easy to learn MEGA preferred prototype controller expansion board.
|Max Current||500mA when Arduino is powered by a suitable power supply connected to the Arduino power jack|
|Max Current||400mA when Arduino is powered by its USB port|
Description: This is a 16x2 LCD and Keypad shield for Arduino Uno, Diecimila, Duemilanove and Freeduino boards. to provide a user-friendly interface that allows users to go through the menu, make selections etc. It consists of a 1602 white character blue backlight LCD. The keypad consists of 5 keys — select, up, right, down, left and reset. To save the digital IO pins, the keypad interface uses only one ADC channel. The key value is read through a 5 stage voltage divider.
