User Activity

i need a dc-dc step down power supply where the input varies from 45-55volts and required output of 5volts and 10amps
i need to interact with 10sensors which can be connected threw SPI bus alone. so i was looking for a microcontroller where i can hook all 10 SPI sensors
i want to have my CNC system moments feedback, which involves displacements of 0.01mm sensitivity
