The product comes packaged in a static-shielding bag, with a stapled colour cardboard hanger top and a colour label on the front. Power can also be fed through the pins directly if necessary. Unfortunately this is not an Arduino sketch, it’s not running from an Arduino-style bootloader, so for this sort of thing you need to overwrite the Arduino bootloader on your board with the new code, and re-flash the bootloader when you’re done to restore normal Arduino-compatible functionality.

As part of it, they were to develop the FPGA coding required to play music notated in a simple 4-bit tone and 4-bit duration packed into 1-byte format.

The silkscreen is very informative, labelling all the pins and peripheral connections. An enclosed surface mount piezo speaker is provided on the back, with its enclosed nature being sensible as it can generate spike voltages on physical stress. As a bonus, the board retains the polyfuse and diode protection for the input power, which the Arduino Pro Mini forgoes.

This makes for better convenience, although you should be aware of some Leonardo-specific quirkssuch as SPI connections being only available via the ICSP header, faster USB serial connection data throughput but slightly different initialization requirements, and programmer reset problems under heavy USB serial traffic.

There is no on-board voltage regulators, as is the case for miniaturized versions of the Arduino, so you must supply only 5v to this board. Proudly powered by WordPress. This uses a LeoStick as a development tool for a quick test of some code I’m developing, prior to actually developing the custom board for this project.

You also get the board, as well as another anti-static shielding bag with two compact 2.

Quick Review: Freetronics LeoStick (XC4266) Arduino Compatible Board

The integrated piezo can be disabled by cutting a trace, but the tri-colour LED needs to be desoldered, or the resistor pack desoldered to disable it. I have modified the code and got something that compiles with bytes of RAM used, but I have not got this successfully working yet actually mounting the disk. The only slightly annoying factor is having fretronics unplug the SD card wires from the ISP port on the LeoStick before programming, because they’re only accessible at this point, not also on the main headers.

Polyfuse protection and diode protection freetronlcs available. Found it really useful — especially the soldering advice.

Preparation — Soldering the Headers If you wish to use this for re-usable prototyping, you will probably be interested in soldering the provided headers to the board. Click for more about me! To modify the LeoStick for 3.

However, for beginners, this board is slightly less friendly to work with as there is no direct plug-in compatibility with shields and the soldering of the pins can be slightly challenging especially to those without fine-tipped irons and a steady hand.

VIN leostivk 5V coming in out of your computer’s USB port, so this is the regulator input, then a ground on one of the ground pins, and the output of the regulator goes to the LeoStick pin labelled “5V”. Going slow and steady is the way to go.

The LeoStick which is modified for 3. January 26, at 2: You do not have the required permissions to view the files attached to this post.

Also of note is that no solder is included, but the versatility to only use the headers where you need them is appreciated. Reverse Eng Pt 2: To make this lab work, frretronics needed to get some music, and I spent some time transcribing some music from MIDI files using an editor into the byte-oriented binary format.

In the package, you get a colour double-sided page with instructions for getting started, downloading drivers and IDE software and specifications of the board.

Edit the makefile, specify your microcontroller choice atmega32u4, or whatever and clock frequency appropriately, freetronids set the AVR programmer type you’re using eg.

Just this week, I was gifted a Freetronics LeoStick from a colleague at the university, so I decided to take a look at it over the weekend. Arduino-compatible open source electronics Skip to content.
