Power
Pins for supplying 5V power to connected devices.
- VDD
- GND
NUMATO USB-GPIO receives power through the USB port. Therefore, be careful as the USB port may be damaged if the total current consumption exceeds approximately 400~500mA.
By changing the jumper to 1-2 Ext Pwr position, you can also supply current from an external power source through the 5V Ext pin.
Digital I/O
Pins for digital input/output. The voltage level is 5V.
- IO0~IO7
ADC
6 pins can be used as 10-bit (0~1023) ADC. The input voltage range is 0~5V.
- IO0~IO3 (ADC0~ADC3)
- IO6~IO7 (ADC4~ADC5)
