WebThe a4988 runs a buck and a half and the TMC2208 is $3 and TMC2130 is under $10. Why bother with 2007's state of the art? Allegro probably has ceased production of the chip. … WebTo enable UART communication, the jumper on the driver has to be bridged from the middle to the respective position. TMC2208 drivers are in stealthChop mode by default. TriGorilla boards set the configuration pins MS1 + MS2 + MS3 to 5V (high), which will set the TMC2208 into 1/16 stealthChop mode.
