Do you like experimenting with many stepper motors and RC servo actuators at the same time, but do you find it hard to manage it easily due to the numerous cable connections that create a sort of jungle on your desk? Fear no more. We have a solution that will make your life a lot easier, your applications more reliable, and your desk a lot less cluttered!

Our Piglet 01 board has unprecedented power capabilities (up to 800W per axis), unavailable until now for the entry-level market. Getting the computational power from the ‘mother‘ board (the Boar’s Board, to which it must be connected), the microcontroller no longer needs to handle or emulate any of these low-level tasks in software. The acceleration and deceleration ramps of the stepper motors, as well as the PWM outputs and PPM outputs, are managed directly in hardware.

Just reunite the Piglet 01 board with its ‘mother’ and enjoy a complete and reliable control system for multi-axis applications, with the added bonus of having a single, comprehensive development board that allows you to concentrate on doing what you want without having to worry about trying to match different boards that were not designed to work together.

Robotics, 3D printing and other applications have never been so easy!

Architecture overview

Board5

12 STEPPER sockets supporting both 3A and 10A smart stepper controller (driven directly from the hardware FPGA acceleration core);

12 PWM-capable hi-current outputs (5A) driving resistive loads like 3D-printer heaters, mechanical actuators or other loads;

12 Servo-PPM sockets enabling the user to drive the RC servos directly by using the FPGA-PPM acceleration core;

24 digital inputs with embedded pull-ups, available as generic inputs.

Bonus feature:

both the source codes of the Boar’s Board FPGA and of the microcontroller are available under LGPL licence, allowing further modifications and developments by the user community.
