Arduino Pro Mini 5V analogas. This is a 5V Arduino running the 16MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. It has 14 digital input / output pins (of which 6 can be used as PWM outputs), 8 analog inputs, a 16MHz resonator, a reset button, mounting hole pin head. 14 digital input / output port RX, TX, D2 to D13; 8 analog input ports A0 ~ A7; 1 pairs TTL level serial transceiver port RX / TX; 6 PWM port, D3, D5, D6, D9, D10, D11; Atmel Atmega328P-AU microcontroller; Supports serial download; Support for external 3.3V ~ 12V DC power supply; Support 9V battery power; Clock frequency of 16MHz; Size: 33.3 * 18.0 (mm).

The microcontroller of this board is ATmega 328P-mu. The microcontroller of the original ARDUlN0 pro mini is ATmega 328P-AU. The performance and function of these two IC is same because of the same silicon core of IC while the only difference is there figure. The power IC of our board is AMS1117. The max input voltage of this IC is 15V DC while the original board is 12V. The max output current of this IC is 800mA* while the original board is 500mA. It can be used for more devices as power supply. Some simple application can operate without any other power IC. There are 20 pins can be used as digital I/O, of which have 5 multiplexing pins. There are 8 pins can be used as analog inputs, of which have 5 multiplexing pins.

The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications. The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling). Features: Simple step and direction control interface Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step Can interface directly with 3.3 V and 5 V systems Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout Short-to-ground and shorted-load protection 4-layer, 2 oz copper PCB for improved heat dissipation Exposed solderable ground pad below the driver IC on the bottom of the PCB Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information) Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) 45 V maximum supply voltage Built-in regulator (no external logic voltage supply needed)
