REva
The REva is the Raisonance 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.
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,
- USB powered, no external power required.
- VDD settings for 1.8v, 3.3V and 5V microcontrollers
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 5.5 mm jack connector with ground signal on the outside.
Operating Modes
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 connection cable and an additional external 9V power supply (not furnished) for the REva. It is advised to break only the boards apart when required by your application.
Note that 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:
- REva with embedded RLink: REva and RLink boards are attached, no connection cable is required and power is supplied by the USB connection (see picture).
- USB power supply for both RLink and REva (green arrow)
- On board ISP/ISD communication (magenta arrow)
- 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 picture).

- External power supply for REva (9V DC, set jumpers to jack position (red arrow)
- Cable ISP/ISD communication (magenta arrow)
RLink
RLink is a USB interface device designed by RAISONANCE that allows in-circuit debugging and in-circuit programming of various microcontrollers, including all the ST7 devices supported by RIDE. The functionalities of this embedded version of RLink are the same as the stand alone version.
Daughter Boards
The daughter boards contain all the components dedicated to a specific target, including the microcontroller itself, a clock selector and other device dependent features.
Additional ST7 and STR7 components will be soon available. Please check this web page again for more information.
! Important !
Note that The different ST7xx-DB daughter boards can be also used with the STR7xx-SK starter kits, while the different STR7xx-DB daughter boards cannot be used with the ST7xx-SK or uPSD-SK (soon available) starter-kits, but only with STR7xx-SK starter kits, due to a software restriction.
