Latest News


The X-Monkey is now available for purchase on our X-Monkey product page.

Leveraging the past success of the Monkey platform, X-Monkey has been upgraded in key areas to increase performance and capability while being backwards compatible to existing projects.


Two manuals are now online to help get you familiar with X-Monkey. The User Manual describes the hardware and electrical design. The Software Development Guide is new, and gives an overview of project structure and programming for the unit.


The connectors, interfaces and mechanical layout of the new Monkey has been changed to optimize connectivity and group by function.

Input power is now a dedicated polarized JST connector to reduce accidental input power issues.

The board now has a symmetrical hole mount pattern with a 1.8" x 3.35" outline. X-Monkey only weighs 33 grams!

Please see our blog for the latest updates...

Impact to Existing Monkey Users


The impact to existing Monkey users that develop their own source code is minimal. The same software development tools and project structure has been maintained with maintenance upgrades as needed.

Non-source code and custom project users:

If you ordered Monkey units with stock software or with custom software from us before, and want to make sure X-Monkey will support your project, it will. We will upgrade any past custom projects to the X-Monkey platform when ordered.

Source code users:

Upgrade to X-Monkey project code will be you ordered Monkey units with stock software or with custom software from

It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software
