The Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

This 2014 designed board uses SMD hardware which reduces the cost but has the same functionality. With more board real-estate there is a new header section for key IOs such as UART I2C and Power.

USB cable included. These devices have the CH340 chip - drivers for Windows and Mac are widely available.

Features:

  • This generic model is completely compatible with the genuine Arduino® Uno. We also stock the genuine made in Italy version.
  • Microcontroller: ATmega328
  • Operating Voltage: 5V
  • Input Voltage (recommended): 7-12V
  • Input Voltage (limits): 6-20V
  • Digital I/O Pins: 14 (of which 6 provide PWM output)
  • Analogue Input Pins: 6
  • DC Current per I/O Pin: 40 mA
  • DC Current for 3.3V Pin: 50 mA
  • Flash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader
  • SRAM: 2 KB (ATmega328)
  • EEPROM: 1 KB (ATmega328)
  • Clock Speed: 16 MHz

  • UV is important to reptiles (and people) in processing vitamin D3 which is needed to absorb calcium. Without it reptiles often suffer from Metabolic Bone Disease (MBD) which leads to weak bones and can be fatal. Thankfully, pet shops have the answer, UV producing globes which can stave off the dreaded MBD. These are in the form of T8 florescent tubes or compact florescent globes and go for $50+ each. And, yeah, they need to be re...

  • Using a few bits and pieces, this ordinary coffee grinder now has two presets to run the motor for a programmable length of time. The idea being that the grinder running for a set amount of time will deliver a certain amount of coffee each button press meaning the beans can be stored unground, keeping them fresher for longer. I completed this project for a friend, Ian, who lives for coffee. Ian wanted the same functionality in h...

    I like the price. Not sure why it is cheap, possibly because it may not have pull-up resistors built into digital IOs , but works perfectly for me using analog inputs and digital as outputs. Bargain :) (Posted on 17/08/2017)

    A great, cheaper alternative to the Arduino Uno. But found the lack of printing on the headers a bit of an inconvenience. (Posted on 4/05/2017)

    This is a good little China-duino. You will need to grab some extra drivers for it, but that was reasonable straight forward. There are a few differences from a stock Arduino, but all of them good. It works the same without breaking the bank. (Posted on 6/12/2015)
