Adafruit Mini 8x8 LED Matrix w/I2C Backpack - Red IMU Sensors The DRV8434A offers several microstep

The DRV8434A offers several microstep modes that the A4988 does not

though they will typically quickly overheat under such conditions and go into thermal shutdown

The circuit board is laminated and sealed with a waterproof gasket and breathable composite waterproof glue so that the heat generated by the circuit board can be dissipated freely

It comes preprogrammed with example firmware and an Arduino-compatible bootloader

A fun way to make a small display is to use an 8x8 matrix or a 4 digit 7 segment display . Matrices like these are 'multiplexed' so to control 64 LEDs you need 16 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there's a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all, wouldn't it be
