ML4024 Hardware
The subsequent sections cover the essential parts in the hardware, for board operation and
testing.
3.1 Power-Up
To power up the ML4024 host, steps are as follow:
The host TOP is where the cage is mounted
Two options are available to power up the board, through power connector J43:
Using dual supply, 5V AND 3.3V taking into account pins distribution, where SMD
jumper R5 must be populated
Using single supply that should be connected to 3.3V Pin, where SMD jumper R3 must
be populated
Connect the host to your PC using a Type-B mini to Type-A USB cable.
