Ordering Info and Specifications
Device numbering scheme is as follows:

All DS1206B boards are equipped with 1024KBytes of flash memory.
- "RS" version: "true" RS232 port on the DB9M connector, power jack and "12V"-to-3.3V power regulator, optional "12V" power on pin 9 of the DB9M (software-controllable).
- "TM" version: TTL serial port on the pin header connector, power jack and "12V"-to-3.3V power regulator.
- "TS" version: TTL serial port on the pin header connector, direct 3.3V power input.
"TM" and "TS" versions are not standard and cannot be ordered from our online store. Contact Tibbo if you wish to order DS1206B devices in "TM" or "TS" configurations.
