Key features
The PCPU is a compact, low-power control unit for NewSpace payloads, managing up to 8 heater channels and stepper motors with 200 steps and 1.8° accuracy. It delivers high-resolution temperature readings (±0.1 K) and interfaces with a higher-level payload controller via serial UART RS-422 interface. It supports memory-mapped software control for system management where default values are written in FLASH memory while operating values are accessible in SRAM.
Equipped with a secondary power supply and EMI filtering, its modular design and integrated calibration data ensure precision and reliability in demanding environments. Additionally, it provides housekeeping measurements of current monitoring for 8 output lines with ±0.1A accuracy.
Customization
All features can be modified by customization.
