H. Connectors
J5: DC power input connector
A 12V to 19V DC power supply with rated current higher than 3.5A must be connected to this 5.5mm/2.5mm power
connector to operate. Any standard laptop AC-DC adapter (not included) can be used. High current linear power
supply would be nice to have but not a necessary. Inside is positive terminal.
J6: DC power input connector alternative to J5
A 12V to 19V DC power supply with rated current higher than 3.5A can also be connected to this 2-pin 5.0mm terminal
to operate. It
’s internally connected to J5.
J1: 3.3V pure battery output voltage rail in 2-pin 5.0mm terminal
This output is galvanic isolated from all other output and input. It comes with over current and over discharge
protections. As well as relay protection. A 5A fuse F6 is connected to the output for additional current protection. It is
also possible to connect this output in serial with other isolated output rails to extend the output voltage range. Highly
recommended for DAC board and clock board.
J2: 3.3V pure battery output voltage rail in 2-pin 5.0mm terminal
This output is galvanic isolated from all other output and input. It comes with over current and over discharge
protections. As well as relay protection. A 5A fuse F5 is connected to the output for additional current protection. It is
