What people are saying about XLR8
Although Arduino is an excellent platform for rapidly and inexpensively building new product designs, it is resource limited. Alorium Technology’s XLR8 board solves this problem in a cost-effective manner by integrating an Arduino-compatible processor into an FPGA with custom Xcelerator Blocks that significantly improve Arduino-based projects.
- Based on the Arduino Uno
- Matches the Uno’s physical footprint – including pin headers for attaching shields
- Mounting brackets or shields that fit Uno will also fit XLR8

What’s an Xcelerator Block?
An Xcelerator Block is an optimized hardware implementation of a unique processor intensive function. Since everything needs a cool acronym, we simply refer to one of these blocks as an “XB”.
XLR8 ships with pre-installed XBs that target application-specific behavior. These are listed on the right. XLR8 can be field-updated to change the XBs implemented on the FPGA. Learn more about XBs on the Xcelerator Blocks page.

Floating Point Math
OpenXLR8 is the methodology that allows XLR8 users to create their own custom Xcelerator Blocks and integrate them into the FPGA.
XLR8 is a drop-in replacement for an Arduino Uno with an interesting twist. It is an Arduino-compatible board that uses a Field-Programmable Gate Array (FPGA) as the main processing chip.
The FPGA provides a reconfigurable hardware platform that hosts an ATmega328 instruction set compatible microcontroller.
The FPGA also accelerates specific functionality that is slow, problematic or even impossible for an 8-bit microcontroller.
The FPGA-based hardware acceleration and offload provided by XLR8 results in significantly improved performance in the same physical footprint and using the same tool chain as standard Arduino Uno boards.
XLR8 is a great solution for accelerating your Arduino-based applications and projects!
The History of XLR8
The XLR8 concept was born as a result of brainstorming ideas for how we could offer the advantages of FPGA processing and acceleration to the Arduino ecosystem. At the same time, one of our own makers was running into some problems with a home project. The rest, as they say, is history.
Here's our Kickstarter video from last fall that tells the story.
Rev 1 Prototype
This is the first version of XLR8 that we designed. This board went from concept to hardware in our labs in about two months, and it worked like a champ!
Rev 2 of the XLR8 board includes level shifting circuitry to provide true 5-volt compatibility for legacy 5V shields. There were also some small mechanical changes and a new color.
The production version of our board includes a new silk screen, some additional test points for automated production testing, and some minor circuit modifications.
