Easy to use with Trinamic drivers

I’ve purchased two of these boards. One from WitBot, one from BIQU. Both boards are identical from BigTreeTech. They are well appointed and well thought out. Converting them to Trinamic drivers only requires adding a jumper for each driver you need to use. Modifying Marlin and tuning the steps per unit, etc. took a fair amount of time. But modifying the board was easy. I used the Marlin 2.0 bug fix located at BigTreeTech’s git hub site. It has the pin assignments for the Trinamic drivers already set. I will buy these again.
