ZM3E4 is ZONESTAR's latest 32bits 3D printer control board. It is a feature rich electronics solution for Reprap and other CNC devices. It built in a STM32F103VET6(or compatible) MCU on board, which has 256K Flash ROM and 48K RAM, working frequency is as high as 72MHz. ZM3E4 used 4 layers of circuit boards, which has better heat dissipation effect and anti electromagnetic interference capability and reliability. ZM3E4 has 8 motor driver module sokect, it can support up to 5 extruders. Default it supplied with a test frimware and you can upload own firmware from SD card.
