3.1 Intel® Edison kit for Arduino* header signal list
The Intel® Edison kit for Arduino* digital signals can be configured as input or output. When programmed as an
input, a GPIO can serve as an interrupt. The Intel® Edison kit for Arduino* 1.8 V I/O are translated to 3.3 or 5 V using
SN74LVC1T45 dual supply bus transceivers with 3 state outputs. Both outputs go tristate if either supply rail is at
ground. The port direction is referenced to VCCA. The drive level for the transceiver is: ±4 mA at 1.8 V, ±24 mA at
3.3 V, and ±32 mA at 5 V.
Note: Drive level at 1.8 V is for reference only – pertains to drive level towards the Intel® Edison compute module.
