Arduino Pro Micro

The Pro Micro is similar to the arduino Mini Pro except with an ATMEGA32U4 on board. This chip makes a big difference since it can also be used as a human interface device. The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with bulky external USB interface. This little board does all the Arduino functions you are familiar with: 4 channel 10-bit ADC, 5 PWM pins, 12 DIOs, as well as hardware serial Rx and Tx connections. Running at 16 MHz and 5 V. This little microcontroller can go anywhere. There is a voltage regulator on board so that it can accept a voltage of up to 12V.

  • 12 digital I/O pins (5 PWM)
  • 4 analog input pins (10 bit each)
  • Input voltage 5-12V (It has an internal regulator)
  • Output voltage: 5v
  • Maximum total output current 150mA
  • ATMega 32U4 running at 5V/16MHz
  • Supported under Arduino IDE v1.0.1
  • Micro-USB connector for programming
  • 4 pines x ADC de 10 bits
  • Rx and Tx Hardware Serial Connections
  • 12 digital inputs/outputs of which 5 can be PWM.
  • Dimensions: 3.31cm X 1.78cm

PinOut

  1. VCC: Power pin. It must receive a 3.3V or 5V power supply, depending on the module specification.
  2. GND: Ground pin. It must be connected to the ground terminal of the system or power supply.
  3. SDA: Bidirectional data line for I2C (Inter-Integrated Circuit) communication. This pin is used to send and receive data to and from the SI5351 module.
  4. SCL: Clock line for I2C communication. This pin provides the clock pulse to synchronize data transmission between the master device and the SI5351 module.
  5. CLK0, CLK1, CLK2: These pins are configurable clock signal outputs from the SI5351 module. You can use them to generate different frequencies and waveforms according to your needs.
  6. MS0, MS1, MS2: These pins are register bank select pins for the SI5351 module configuration. They set the register bank that the I2C bus accesses.

The Si5351 is a Programmable Frequency Clock (PLL) generator produced by Silicon Labs. It is widely used in electronic projects and Radio Frequency (RF) applications, such as building oscillators, frequency synthesizers, software-defined radios (SDR) and other projects that require a highly accurate and stable signal source.

The Si5351 has the ability to generate three independent clock signals with frequencies ranging from a few kilohertz to a few hundred megahertz, making it suitable for a wide range of applications. In addition, it is programmable through an I2C communication interface, allowing designers to easily adjust the frequency and phase of the output signal accurately and quickly.

This module has a precision 25 MHz crystal reference and an internal PLL and dividers, so it can output almost any frequency from <8 KHz to over 160 MHz. The Si5351A Clock Generator is an I2C clock generator. It uses the onboard precision clock to control multiple PLLs and clock dividers using I2C instructions. By configuring the PLL and dividers you can create precise and arbitrary frequencies. There are three independent outputs, and each one can have a different frequency. Outputs are 3Vpp, either via a breadboard compatible header or for RF work, an optional SMA connector. We put this handy little chip on its own PCB, with a 3.3V LDO regulator so it can be powered from 3-5VDC.
