Supply Voltage Terminal (12/24V DC)
Intro
The terminal “12V/24V” and “GND” on the upper side of the NEXTuino terminals are for the supply voltage connection. You can supply the NEXTuino with 12V or 24V. The range of voltage should be in the range of 10.8V–13.2V and 21.6V–26.4V direct voltage.
IMPORTANT! Please make sure to use a stabilized supply voltage!
The maximum supply current is not the same for MINI, MAXI and MEGA:
- MINI: 8A
- MAXI: 20A
- MEGA: 30A
Exceeding the maximum current would lead to a fusing of the internal fuse of the NEXTuino.
LED Indicators
The right supply voltage will be indicated by 2 LEDs. The LEDs are marked with “12V” and “24V”. Depending on the supply voltage the LEDs will show the state of the NEXTuino.
| 12V LED | 24V LED | State |
|---|---|---|
| green | orange | 12V supply voltage active |
| orange | green | 24V supply voltage active |
| orange | orange | Supply voltage outside of supported range |
INFO: After connecting the supply voltage NEXTuino will start immediately executing the loaded program!
