2.3Power Supply The on-board power supply circuitry allows various power supply configurations. This

		gives the user the capability to power the devices in the 3V and in the 5V voltage range.
2.3.1	Power Supply	The power supply source can come from two different and exclusive sources:
	Sources	either from the JACK PWR connector
		either from the 2-point sip EXT connector.
2.3.1.1	JACK PWR	The Jack power connector implemented on board is a female Jack connector with inter-
	Connector	nal 2.1mm conductor. It requires a male JACK outlet with 2.1mm capability.

No specific polarization is mandatory as on-board diode rectifier gives a protection against inadvertent polarization invertion.

When using the JACK power supply, the board is powered with a 5V voltage.

Hardware Description

Figure 2-3. Male JACK Outlet and Wires

	Note: Do not mount more than one power supply source on AT89STK-11 Board.
	Note: There is a diode voltage level between the negative output of the power supply
	and the “GND”. This could introduce some voltage gap during measurement
	and instrumentation.
2.3.1.2 External EXT	The battery power connector implemented on board is a male two point SIP connector.
connector	It requires an external power cable with a female 2 points connector.
	When powered though this interface, polarization is mandatory as no protection is given
	on board.
	The EXT power supply circuitry support input supply from 2.7V up to 5.5V DC.
	Figure 2-4. EXT PWR Female Connector / Cable

		Note: Do not mount more than one power supply source on board.
		Note: Keep SP1 closed when using the EXT input
2.4	Reset	To be compatible with Atmel microcontrollers which have (or not) its on-chip RESET cir-
		cuitry (c.f.microcontroller datasheet), the board provides a RESET signal witch can
		come from 2 different sources:

2.4.1Power-on RESET The on-board RC network acts as power-on RESET.

2.4.2RESET Push Button By pressing the RESET push button on the board, a warm RESET of the microcontroller

is performed.
