3. REva motherboard
This chapter describes the REva's eva uation features and their imitations. Features are grouped into
thematic areas.
3.1 Power supply
You can choose the vo tage to be used on the who e REva board as we as on the daughter board.
On the REva v3.0 the daughter board automatica y configures the regu ator and defines the possib e
sources for VDD.
3.1.1 External power supply
The REva motherboard can be powered by an externa power supp y which is not provided.
The characteristics of the power supp y are:
●9V DC output, (5V for STR9 kits)
●2.1 x 5 mm jack connector with ground signa on the outside.
3.1.2 Possible power supply configurations
There are 3 possib e modes for the configuration of the power supp y:
Power supply configuration mode Scheme
Regu ated vo tage supp ied from RLink
●The vo tage of VDD is automatica y
configured on the daughter board
●To be used in the range of [1.8V, 3.3V]
(because RegIN is around 4.7V).

Power supply configuration mode Scheme
Regu ated vo tage supp ied from the Jack
●The vo tage of VDD is automatica y
configured on the daughter board
●To be used in the range of [1.8V, 5V] with
an externa fi tered power supp y (typica y
6V, but 5V is recommended for VDD ower
than 3.6V).
5V supp ied from the USB ink
●To be used ONLY with 5V daughter
boards
● Other daughter boards are genera y
protected (the USB 5V wire can be opened
by the daughter board)
●The exact vo tage is NOT 5V, but around
4.8V because of a ow drop diode on the
RLink.
3.1.3 Features
●A jack for the connection of auxi iary 9V power supp y to power the REva board in broken
apart mode. Shou d you require one, the 9V power supp y shou d output 9V DC and have a
2.1 x 5 mm jack with the ground signa on the outside.
●A two-position jumper for configuring the regu ator input. When the jumper is in the Jack
position, the regu ator input is the externa 9V power supp y. When it is in the USB position,
the regu ator input is the USB power supp y of the embedded RLink.
●A two position jumper to se ect the VDD source. The “regu ated” positions have a meaning
that depends on the connected daughter board (autoconfiguration of the power supp y area by
the daughter board – refer to the daughter specific chapter in this documentation).
●A green LED which is it when the REva board is powered.
3.1.4 Limitations
The USB 5V is actua y 4.8V because a ow drop diode is connected between the USB connector and
the board, to protect the PC. For an accurate 5V power supp y, use an externa power supp y.
Once the RLink has been separated from the REva motherboard, the USB power supp y is no onger
connected to the power supp y area. The use of an externa 9V DC power supp y is mandatory, the
“Regu ator Input” jumper must remain in the “Jack” position and the “VDD se ection” jumper must
remain in the (1) position.
With a 1.8V power supp y, the LEDs on the board are dim and some features are not avai ab e (seria
communication, I²C EEPROM and temperature measurement).
