Hi , all.· I am from Taiwan.

i have a question. When i read the boe manual , it said·that 6-volt (use the battery pack) is better while using boe. Because·highly voltages will

damage your servo.May·i use 9-volt battery for boe ?··Or it is decided by the servo what i use ?· Assume my servo is continuous rotation servo.

It is a product of Parallax.·How many voltages·are better for me?

It depends.

There is a jumper on the BOE that is used to set what voltage is supplied to the servo connectors. The two positions are Vin and Vdd. The Vin setting is the BOE power supply voltage. The Vdd setting is the regulated +5V used by the Stamp and other components. If the jumper is set to Vin and you have a supply voltage greater than 7.5V, you will damage your servos. If you use the Vdd setting and have more than one servo, it's possible for the servos to draw more current than the regulator can supply. This won't damage the regulator, but the Stamp may reset as the +5V power supply drops too low because of the current drain. It's best to use a power supply voltage between 6V and 7.5V and use the Vin setting of the jumper.

Note that a 9-volt "transistor" battery won't produce enough current for a servo, anyway, if that is what you are trying to do.

Mike , Allan , thank you so much.

i will use 6-volt for my boe.^^
