The Pro Micro is similar to the Arduino Mini Pro except with an ATMEGA32U4 on board. This chip makes a big difference as 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 interfaces. This little board does all the Arduino functions you are familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIO, as well as hardware serial Rx and Tx connections. Running at 16MHz and 5V, this little microcontroller can go anywhere. There is a voltage regulator on board so it can accept voltage up to 12V.

  • 12 Pins digital I/O (5 PWM)
  • 4 Pines de entrada analógicos (10 bit c/u)
  • Input voltage 5-12V (Has internal regulator)
  • Output voltage: 5v
  • Total maximum 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 1.78 cm

  • VCC: Power pin. Must be powered by 3.3V or 5V depending on module specification.
  • GND: Ground pin. Must be connected to the ground terminal of the system or power supply.
  • SDA: Bi-directional data line for I2C (Inter-Integrated Circuit) communication. This pin is used to send and receive data to and from the SI5351 module.
  • SCL: Clock line for I2C communication. This pin provides the clock pulse to synchronize data transmission between the master device and the SI5351 module.
  • 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.
  • MS0, MS1, MS2: These pins are register bank select pins for configuring the SI5351 module. They set the register bank accessed by the I2C bus.

The Si5351 is a programmable frequency clock (PLL) generator produced by Silicon Labs. It is widely used in electronics projects and radio frequency (RF) applications, such as building oscillators, frequency synthesizers, software defined radios (SDRs), and other projects that require a high-precision 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 via an I2C communication interface, allowing designers to easily adjust the frequency and phase of the output signal accurately and quickly.

Si5351a Clock Generator – 8Khz to 160Mhz + 3 SMA female connectors

This module has a precision 25MHz crystal reference and an internal PLL and dividers, so it can generate almost any frequency, from <8KHz up to over 160MHz. The Si5351A clock generator is an I2C clock generator. It uses the onboard precision clock to control multiple PLLs and clock dividers using the I2C instructions. By configuring the PLL and dividers you can create precise, arbitrary frequencies. There are three independent outputs, and each can be driven at a different frequency. The 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. We also put level shifting circuitry on the I2C lines so you can safely use this chip with 3V or 5V logic.
