Duet3D | Duet 3 Expansion Board 3HC V1.02a

The Duet 3 Expansion Board 3HC V1.02a is an improved version of the 3HC V1.02. It is a fully featured expansion board for the Duet 3 motherboards. The board contains a powerful 32-bit Atmel ARM Cortex-M4F microcontroller with a speed of up to 120 MHz. The part is also equipped with 3x 5 A PWM outputs for extruders, 6 PWM outputs for fans, 6 I/O connectors with 3.3 V output signal level and 30V outputs. In addition, this board has improved input protection on Tacho/Io and inputs that measure temperature. Finally, the 3HC V1.02a has other MOSFETS, but these do not change the top performance of this expansion board.
