The CAN Bus interface is available on the 8/16 Digi Connect ME 9210, Wi-ME 9210
variants.
When using the 8/16 ME 9210/ Wi-ME 9210 CAN Bus, the DTR (9210 signal GPIO 6) line
must be tri-stated. When the DTR signal (9210 GPO/I 6) is used, 9210 GPO/I 15 must be tri-
stated. These two 9210 signals are wired together on the 9210 modules.
The Digi Connect Wi-ME 9210 module does not provide pins 1-6.
When using I2C, make sure to put a 10k pull up on the SDA and SCL lines.
