REva User Guide: Mother Board 1. Presentation
1. Presentation
The REva is a universal evaluation board that has been designed for quick
and easy evaluation of a wide range of microcontrollers. It is made up of a
generic REva mother board with embedded RLink in-circuit programmer and
debugger, and a daughter board featuring a target microcontroller.
IMPORTANT NOTE:
This manual describes different versions of the REva boards. The major part
of this User Guide refers is common to all the existing REva boards. For the
parts where the boards differ, a notice (in blue) will indicate it.
Version Short description
REva v1 First version of the REva board.
REva v2 Very similar to V1.0, but the voltage of the regulator is now fixed by the
daughter board itself (instead of a set of jumpers on the REva board).
REva RF 'ZigBee' The REva RF 'ZigBee' is designed for RF applications and features an
extension connector to plug a RF external module.
REva v3 The RLink is not breakable anymore. New peripherals are also added: LCD
monitor, MEMS accelerometer, ...
A DIFFERENT MANUAL DESCRIBES THE REva v3 (AND LATER).
The REva's key features include:
●Digital and analog I/O evaluation features including on-board LEDs,
buttons, switches, external analog connector, temperature sensor
and potentiometer,
●On-board I²C EEPROM and bus extension connector,
●On-board RS232 driver and DB9 connector,
●SPI, CAN and USB connections (depending on the target device),
●Embedded RLink for in-circuit debugging and in-circuit programming,
●VDD settings for 1.8V, 3.3V and 5V microcontrollers,
●USB powered, no external power required.
This chapter gives an overview of the REva package and the physical
characteristics of the mother board.

1.1 Description of the delivered package
The REva package includes:
●1 REva mother board (see Illustration 2),
●1 RLink attached to the mother board (see Illustration 2),
●REva daughter board(s), depending on the purchased kit,
●all required cables,
●1 RAISONANCE software CD,
●1 QuickStart tutorial,
●some target microcontroller specific documentation.
The REva mother board can be powered by an external power supply which is not provided.
The characteristics of the power supply are:
●9V DC output,
●2.1 x 5 mm jack connector with ground signal on the outside.

1. Presentation REva User Guide: Mother Board
At the time of manufacturing, the REva and the RLink are connected to allow in-circuit debugging and
in-circuit programming of the microcontroller on the REva daughter board without additional power
supply or cables.
The two tools can also be easily broken apart so that both the REva and the RLink can be used
independently, or together. This requires the use of the furnished cable and an additional power supply
(not furnished) for the REva.

REva User Guide: Mother Board 1. Presentation
Note: When separated from the REva, the RLink has the same in-circuit debugging and programming
characteristics as the stand-alone RLink version 2.0.
As a result there are two possible configurations for using the REva:
●“Attached Mode”: REva and RLink boards are attached, no connection cable is required and
power is supplied by the USB connection (see paragraph 2.1).
●“Broken apart mode”: The REva is connected to the RLink (or other tool that supports in-
circuit debugging and programming) via a connection cable. Power is supplied by a 9V
auxiliary power supply (see Illustration 3 and paragraph 2.2).

1.2 REva-RLink connection
The REva and the RLink are connected by eight points at the time of manufacturing. Through these
points, 16 signals are passed including those for:
●in-circuit debugging
●in-circuit programming
●USB power supply
●the grounds of the two boards
!!! Warning !!!
After the boards are broken apart, you must use the provided cable to connect the boards and
an external 9V power supply. Only break the boards apart if it is required for your application.
To break apart the two boards, place the separation along the edge of a desk. Then, press down on the
RLink with one hand while maintaining the mother board with the other hand.
