[Arduino Boards] This Pro Micro 5V 16M Mini Leonardo Microcontroller Development Board For Arduino development board has 4 channel 10 bit ADC, 5 PWM pins, 12 DIO, and a hardware serial connection Rx and Tx you are familiar with Running on 16MHz and 5V, this board will remind you a lot of other Arduino compatible boards that you like. There is a voltage regulator on board, so it can accept up to 12V DC. The Micro is a microcontroller board based on the ATmega32U4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard. The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. If you supply an unstable power supply board, be sure to connect to the “RAW”, not on the VCC pin. It has also added a PTC fuse and diode protection to the power circuit and to correct the RX and LED TX circuits. Features : ATMEGA32U4 running in 5V / 16MHz Support Arduino IDE V1.0.1 Micro USB interface programming on the board Four 10-bit ADC pin 12 digital I / O (5 PWM capability) Rx and Tx hardware serial connection.

Nano Board R3 with CH340 chip without USB Cable compatible with Arduino (Unsoldered)
[Arduino Boards] The Nano Board R3 with CH340 chip without USB Cable chipboard is based on the famous Arduino platform and does all the functions of Uno, but with a smaller footprint. The Nano Board R3 with CH340 chip without USB Cable is vital for your small project where you don’t need much of a pin-outs but the small size is very important to make it look good. This Nano equips a low-cost USB-Serial Chip that makes it less in price than Nano with FTDI USB-Serial Chip used on older versions of Arduino Nano. The Nano Arduino is a small, complete, and breadboard-friendly board based on the ATmega328 (Nano R3). It has more or less the same functionality of the Uno but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one. The Nano can be power via the mini-USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.
