This breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 V to 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling). The driver has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications. This board ships with soldered 0.1″ male header pins and heat sink.

This case got the best thermals for the RPi4; the power button is best for a safe and easy power off. Got it delivered with 2d; thanks for the quick delivery.
We have an opportunity for the requirement of JCG046L LTE Antenna. Kindly share your best quote and let us know the lead time.
Also please provide the test report. Specifically, they need details on Return Loss, VSWR, and Average Efficiency for all 4G bands supported by the antenna.
