A breakout board for the Texas Instruments EK-TM4C1294XL Launchpad running the grblHAL TM4C1294 firmware by Terje Io.
This is a Frankenstein style child of GRBLHAL2000 and CNC_Boosterpack.
There were two objectives for this:
- follow known-working proven schematics - no questions asked
- keep it manufacturable by JLCPCB with the least costs for extended parts
