This circuit board attempts to implement this schematic: (by Palliser, not me… see the Arduino Forum link below for details)

Due CAN Interface Schematic

http://forum.arduino.cc/index.php?topic=131096.msg1011501#msg1011501

The DB9M connectors are designed for this cable.

Another pinout for CAN with DB9 is sometimes used (CANH & CANL on pins 7 & 2). Solder pads on the button side allow reconfiguring for the other pinout.

Recommended Components:

Qty   Digikey P/N       Description
---   -----------       -----------
 2    296-27991-1-ND    CAN transceiver
 2    445-7660-1-ND     Capacitor, 10uF, 805
 2    399-1170-1-ND     Capacitor, 0.1uF, 805
 2    609-4003-ND       DB9M connector
 2    CF14JT120RCT-ND   Resistor, 120 ohm
 2    3M9447-ND         Header, 2 pin
 2    3M9580-ND         Jumper

Battery Pack Load

2 layer board of 0.56 x 0.61 inches (14.1 x 15.4 mm).
Shared on November 5th, 2013 19:05

Provides a minimal load to keep a “device charging” battery pack turned on. Useful for powering low-power projects well under the pack’s minimum load where it would normally turn off automatically.
