Crowd Supply JuicyBoard Robotic Control System
Crowd Supply JuicyBoard Robotic Control System is the foundation of a modular, open-source platform to build a custom 3D printer, CNC router, or any other device driven by stepper motors. JuicyBoard is not pre-populated with any drivers, switches, or other functions. The board only includes the components for common core functions (e.g., microcontroller, USB port, SD card, etc.). Add just the necessary functional modules for applications with this modular approach that gives many advantages over static board designs.
There are two models of the baseboard
• The R1000AX includes fifteen feature slots and is 175x65.5mm
• The R1000A is a more compact model that includes ten feature slots and is 125x65.5mm

6. 3.3V switching regulator (1.5A output): powers 3.3V logic
7. LM5060 hot swap controller [R1000AX Only]: protects the system from overshoots, undershoots, and overloading
8. LPC1769 ARM Cortex M3 MCU @ 120MHz
9. 100A PSMN1R2-30YLC,115 NFET Switch [R1000AX Only]: used for shutting down the system in case of faults or emergencies
10. Feature Slots: 15 for R1000AX and 10 for R1000A
11. Micro SD Card Socket [R1000AX Only]
12. Full-Size SD Card Socket [R1000AX Only]
R1001: Smart Stepper Motor Driver
Based on TI's DRV8825 chip, the NEMA stepper motor driver is a high-performance stepper driver capable of micro-stepping at 1/32" resolution. Current can be digitally set for every driver in 10mA increments. The R1001 includes temperature/voltage/current monitors for real-time performance measurement and fault detection.
R1002: Quad 1A DC Low Side NFET Control Switches
This module can control four small functions (e.g., fans, LEDs) that consume less than 1A and run at the high input voltage.
R1003: Quad Analog/Digital I/Os
This module connects four microcontroller signals to external components (such as a thermistor or end-stop switch). It can be used for analog and digital signals.
R1007: Quad 20A DC Low Side NFET Control Switches
This module can drive four heaters with strong 100A PSMN1R2-30YLC, and 115 NFETs from NXP, which allows it to run cool, steady 300+ watt heat beds. The R1007 must be powered through its auxiliary supply input. It is optically isolated from JuicyBoard (meaning, it can have its own separate power and ground and can be powered by up to 24V).
R1008: Dual Channel Platinum RTD PT100 Temperature Sensors
This module provides an interface to two PT100 platinum resistor temperature detectors (RTDs) for precision temperature sensing (as accurate as less than 0.2° C error). It can work in 2-wire, 3-wire, or 4-wire configurations.
