Appendix A. Best Practices
This section outlines the best practices for operating the EBC-C413 in a
safe, effective manner that does not damage the board. Read this section
carefully.
Power Supply
Power Supply Budget
Evaluate your power supply budget. It is usually good practice to budget
twice the typical power requirement for all of your devices.
Zero-Load Power Supply
Use a zero-load power supply whenever possible. A zero-load power
supply does not require a minimum power load to regulate. If a zero-load
power supply is not appropriate for your application, then verify that the
single board computer’s typical load is not lower than the power supply’s
mum load. If the single board computer does not draw enough power to
meet the power supply’s minimum load, then the power supply does not
regulate properly and can cause damage to the EBC-C413.
Adjusting Voltage
If you have a power supply that allows you to adjust the voltage, it is a
good idea to set the voltage at the power connector of the EBC-C413 to
5.1 V. The EBC-C413 can tolerate up to 5.25 V, so setting your power
supply to provide 5.1 V is safe and allows for a small amount of voltage
drop that occurs over time as the power supply ages and the connector
contacts oxidize.
Avoid Electrostatic Discharge (ESD)
Only handle the circuit board and other bare electronics when electrostatic
discharge (ESD) protection is in place. Having a wrist strap and a fully grounded
workstation is the minimum ESD protection required before the ESD seal on
the product bag is broken.
Use Proper Power Connections (Voltage)
—When verifying the voltage,
measure it at the power connector on the EBC-C413. Measuring it at the power
supply does not account for voltage drop through the wire and connectors.
The EBC-C413 re5 V (±5%) to operate. Verify the power connections.
Incorrect voltages can cause catastrophic damage.
Populate all of the +5 V and ground connections. Most single board computers
have multiple power and ground pins, and all of them should be populated.
The more copper connecting the power supply to the EBC-C413 the better.
