JuicyBoard is the base board of a modular systems that makes it easy and efficient to build your own robotics application, whether you're building your own 3D printer, CNC, router or any other other application that requires controlling motors.
Our idea is simple, unlike most of control boards we've seen, JuicyBoard is not pre-populated with any drivers or heaters. Instead it only includes the necessary components for common core functions (i.e. Microcontroller, USB port, SD card ... etc) while housing 13 expansion slots aligned in a matrix geometry that allows adding features as needed.
JuicyDriver BoardThis is a NEMA stepper motor driver based on Allegro Microsystem's A4982 chip. It includes its own VREF for individually adjusting motor current, or the option of soldering 2 resistors for a fixed value.
BigHeater BoardThis module can drive 4 heaters with strong 78 Amperes IRLB8748PBF NFETs from Infineon Technologies. Every channel can be individually populated with up to 3 transistors in parallel, allowing steady and cool driving of 300+ Watts head beds.
Upgrade or Expand
The modular nature of the JuicyBoard platform allows for easy future upgrades such as a stronger motor driver. This can be done easily by swapping modules without the need for a major board redesign.
In case any of the modules fail for any reason you can swap it with a new one, avoid PCB rework or even buying a new controller board.
Balance between customizing your application and cost. Only install the features that you need, no more no less!
