- 5x power output channels providing 12V over 8-pin PCI Express type (Molex/39288080) sockets
- Up to 220W per single 12V power output channel
- Output current measurement implemented with Ti/TMCS1100A2QDRQ1 Hall sensors and 12-bit Ti/ADS7828E ADC accessible over I2C
- Power-cycling for each channel implemented with power MOSFETS driven from Ti/TCA9534 GPIO expander accessible over I2C
- I2C bus for current measurements and power cycling is opto-coupled with FTDI/FT4232H-56Q with USB exposed towards an external host
- Auxilary connector (Molex/39281103) exposing 5.0V,3.3V,12V for connecting external peripherals
