KEYESTUDIO Leonardo R3 Microcontroller Development Board with USB Cable Kit for Arduino Project

  • 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.

Ximimark 5Pcs 16CH Analog Digital Multiplexer Breakout Board Module CD74HC4067 CMOS Precise Module For Arduino

  • ... the channel you want. This allows you to connect up to 16 sensors to your system using only 5 pins!.
  • Since the mux/demux also works with digital signals, you can use it to pipe TTL level serial data to or from multiple devices. For example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller. You can then select any one of those 16 devices to listen to. If you want two-way communications,you can add a second board to route your microcontroller's TX line to 16 device's RX lines. By using multiple boards, you can create similar arrangements for I2C,SPI,etc..
  • The internal switches are bidirectional, support voltages between ground and VCC, have low “on” resistance and low “off” leakage, and to prevent crosstalk, perform “break-before-make” switching. The board also breaks out the chip’s “enable” pin, which when driven high, will completely disconnect the common pin (all switches “off”)..
