¹) Functions may be altered by modifying the Argon open source firmware

Electrical characteristics

For detailed specifications, see I/O electrical interfacing and pinout & wiring.

Property	Typical value	Maximum rating	Units

¹) Actual output drive capability may vary from unit to unit. Minimum guaranteed capability is 5 mA.

²) Do not exceed GPO safe operating area (SOA). Loading GPOx pin is within SOA when following equation is true: Voltage_drop_over_GPOx_pin_pair*Load_current < 0.1W. Example: if voltage over GPOx pins is 5V and current 0.01A, then 5V*0.01A=0.05W which is less than 0.1W so the operation is safe. The recommended practice is to drive only high impedance circuits with GPO to avoid overloading.
