PC boards for MRI robogt control, specifically for STM32 motherboard

MainPCB (holds STM32 Nucleo 446RE and FPGA for encoder reading)

PowerPCB (switches for enabling individual ultrasonic motors, +24V in connector, master power switch))

MotorJoint_Splitter (mounted on robot arm)

* Motor Joint Splitter V3 (mounted next to each actuator)

Motorreroute (at motor controller. Splits Tekcelo control signal to use ethernet for a pair of encoders, and 3 wire sin/cos/gnd cable for 250V )

Power: common questions

How big is the Power PCB?

The Power measures 142 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Power?

58 components, from 29 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Power design files?

From the biomimetics/MRIRobot_PCB repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Power design in my own project?

The repository has no license, so all rights stay with biomimetics. Use it as a reference, and ask the author before reusing the design.
