I have interest in more information about your project MSP430-Board for EasyDriver Best regards qgs Hi I could send you the Diptrace files if they would be of any help. My board just connects the necessary pins of the MSP with the pins of the Easy Driver board ... so nothing special here I guess. If you want to use my PCB layout with another MSP Derivate you could just change the foot print for the mcu, the pins and the routing for vcc, gnd, reset etc. ...
