Product Details

Arduino Leonardo Development Boards (with and without headers)

We have two versions of the Leonardo board from Arduino; 761-7324 with headers and 761-7315 without headers.
The Leonardo features an on-board ATmega32u4 microcontroller as well as built-in USB 2.0. This means that your Leonardo board can appear as a keyboard or mouse on your computer once connected. The board can also appear as a virtual (CDC) serial/COM port.

Features & Benefits of the Leonardo
•20 digital I/O pins (7 PWM outputs and 12 analog inputs)
•16 MHz crystal oscillator
•32 KB Flash memory
•2.5 KB SRAM
•UART TTL serial communication
•Power jack
•ICSP header
•Reset button
•5 V operating voltage

Arduino AVR Development Boards

We have a range of Arduino boards at RS that feature an AVR ATmega microcontroller at the core. Most of the boards feature the 32u4 microcontroller with the Mega boards featuring the ATmega 2560 and the Uno/Nano boards featuring the ATmega328 microcontroller.

For the prototyping of embedded, lowest-cost projects the Leonardo outperforms the competition in terms of input/output/special functions per £ pound. With both analogue and digital inputs and outputd, including PWM on several pins, sPI and I2C as well as USB and compatible with shield expansion boards the Leonardo has quickly become the new replacement for the UNO, haivng rather more to offer, with same size shield (PCB) and pin-out compatibility. Note: whist pin locations match, some pin functions have changed - so be sure to adapt your code to reflect the different pin-outs between the Leonardo and UNO, etc. Very fast to learn to program, no special tools needed and free IDE for Windows/MAC and Linux users to program in. very similar syntax and structure to C++, so it also makes a good starting point for those wishing to learn more and go onto PIC chips at a lter date, for example. Internet source code examples widely available with open-source licencing. A really good addition to the popular Aduino range. Has become both my entry-point board as well as my first choice for the more simple, low-speed, smaller code-size (up to 12kB) projects. May struggle to replicate speech, for example - unlike a DsPIC - but at £16 what do you expect ! Easy to learn to use from scratch, using one website- the Arduino playground (www.arduino.cc) and no hidden costs except a micro to USB cable for programming - unless you have a Kindle or equivalent charging cable laying around
