Description

The Arduino Uno is a microcontroller board based on the ATmega328 chip. The Arduino Uno has 14 digital input / output pins (of which 6 can be used as PWM output), 6 analog inputs, a 16 MHz ceramic resonator, a USB connector, a power jack, an ICSP header and a reset button.

The Arduino Uno is by far the most popular development board for beginners and advanced. Because the ATmega328 is not soldered, it can easily be replaced when a catastrophic mistake is made. By buying this (original) version, the Arduino community is supported, so that new platforms can be developed.

Works well! Solid Arduino product
I already knew the Arduino Uno. Great material.

Solid Arduino product Beautiful headers with legible print USB connector is sturdy Sponsors software development Chip is in theory replaceable Real Leonardo is cheaper and better USB connector is more clumsy than micro / C Double assignment of pin 0/1 leads to UART problems Looping through SPI is a waste of pins Looping through I2C without pins
I don't understand the continued love for the UN. They are fine boards, but the cheaper Leonardo from Arduino itself is better in all respects: https: // Opencircuit .nl / Product / Arduino-Leonardo-met-Headers At the UNO it is a pity that SDA / SCL with pin A4 / A5 are connected, same applies to the ICSP header, which is attached to pins 9,11,12 and 13. It's a shame, you have already "lost" 6 pins. Finally, pin 0 and 1 are also double occupied, which are shared with the USB controller. The problem is due to the Atmega 328 chip itself, which simply has too few pins for the R3 layout on the board. 28 pins compared to 44 pins at the 32u4. In short, with a Leonardo you have 8 pins more with a 100% compatible layout, including a double serial port. The double UART alone is worth gold: after all, you can connect modules such as GSM, Bluetooth, GPS, etc. with the option of displaying on the serial monitor. This UNO is not without artifice with Software Serial. With the Leonardo you also get 6 additional analogue inputs (12!), So that you can connect sensors to + 5V and GND virtually anywhere around sensors without using a prototype board. The interrupts are also a bit more extensive. Last advantage of the Leonardo is that it supports USB HID: a Leonardo can be a USB mouse, keyboard, MIDI controller and gamepad! It's the best UNO there is, but it remains a UNO ..... Very 2007! And don't be fooled: any manual written for a UNO can be used for a Leonardo. The only thing to pay attention is: old manuals sometimes want to connect SPI and I2C to the wrong pins (A4 / A5 / 9/11/12/13). You just have to neatly connect it to the ICSP and SDA / SCL pins.

Works well 12 analog inputs Fully UNO shield compatible. Fast compile and upload due to compact code Stack-able Cannot load code if there is a pin connected to port 0
Love it!

Works well! Works well
No counterfeiting and for the same price as with Arduino itself. You can see that in the quality.
