I am going to check the GSM board of fibocom (FE-G5-10) I want to know the connections how can I make? The Fibocom is of TTL so help me to do this .

  • I'm not familiar with the Fibocom GSM board. What you need to do is to examine the below.

    VOH (CMOS) ≥ VIH(TTL)

    VOL (CMOS) ≤ VIL(TTL)

    VOH (TTL) ≥ VIH(CMOS)

    VOL (TTL) ≤ VIL(CMOS)

    Will the TTL (GSM) and CMOS (MCU) source from the common supply? The Voh/Vol/Vih/Vil data are given in the MCU device datasheet.
  • Should not poster's "Less than Descriptive and/or Inspiring" (i.e. FLAWED) Subject Line be "passed over?"

    In addition - poster's judgement of, "What's proper for an MCU-Centric forum" appears equally, "in need of some review..."

    Does not his, "So help me" lurch (beyond) "request" into a "command?"       Is that to be sanctioned - and if so - can that be good?
