What
can I do with CANDIP/AVR?
- CAN SLIO with
your own protocol or with e.g. CANopen,
DeviceNet, SDS, CAN Kingdom etc.
- Smart nodes
with PID algorithms for controlling e.g.
temperature, motors or valves.
- Data
Acquisition via CAN. Add your favorite
SPI/I2C ADC and collect data.
- Home
Automation. Build smart nodes for turning
ON/OFF lights, burglar systems etc.
- Add CAN
simple in an existing system via e.g.
SPI, RS-232 or your own way.
- Education.
CANDIP/AVR offers a very low cost to
learn CAN, we have many starter kits
options.
- If you have a
customer who want to see a prototype or
even a ready product next week.
- Decentralized
smart nodes for e.g. Robots.
- CAN monitor
in an existing system. Add some Leds and
you could monitor e.g valves etc.

Features
- Standard 28
pin DIP board with 0.1" pins, so use
a standard DIP28 carrier.
- Needs only a
5VDC/28mA power source (plus 70mA for CAN
tranceiver*).
- Atmel AVR
type AT90S8515 working at 3.6864Mhz
(other crystals at request).
- 8k user
FLASH, 512bytes user RAM and 512bytes
user EEPROM.
- Up to 13
digital I/O points on DIP28 board, each
capable to sink 20mA as outputs.
- SPI port for
expansion.
- One Interrupt
line availible for user functions (INT1).
- SJA1000 CAN
controller working at 16Mhz, which
supports CAN2.0B.
- 82C250 High
Speed CAN transceiver 1Mbit (ISO-11898).
- CAN
controller can be interrupt driven
(INT0).
- MAX202 RS-232
transceiver which together with the AVR
can send/receive up to 115kbit.
- MAX825M Reset
circuit, the normal RESET and inverted
RESET is on external pins.
- No
interpreted software, it's programmed
with compilers.
- Posibilities
to implement higher level protocols, such
as CANopen, DeviceNet etc.
* Current
consumption for CAN tranceiver variates depending
how many nodes that are attached, but should be
dimensioned for 70mA.

The
picture above shows the CANDIP/AVR
board (both sides) mounted with an AT90S8515,
MAX202, MAX825, SJA1000 and a 82C250 CAN transceiver. You
only need to apply power and connectors of your choice
and you are up running. No hassle trouble shooting
hardware while learning CAN.
