Tom, I notice on BEIER's web site that the specs. for this product say the digital inputs must have a logic high level of 5V or greater.
I know your radio is a Futaba 14MZ, presumably on a surface frequency, or is it a 2.4GHZ version?
My Futaba FASST 10C 2.4GHz radio comes with a warning that it outputs only 2.7Volt logic signals that can cause some older ESCs to not work.
Do you have any knowledge of how this BEIER units operates on lower voltage logic levels?
Regards,
David
Hi David
My radio is running with a standard 40 MHz module. So far I have no plans to convert it to Futaba's fasst 2.4 GHz as 40 MHz is fine and the system has a synth. so that switching channel is easy without crystals.
I think that 2.7V might be too low a voltage for the Beier sound moudle. It might work, but I wouldn't count on it. I think it sounds strange that your fasst reciever is only outputting 2.7V, as this would probably caurse a lot of devices to have operational problems when connected to the reciever.
Most servo's, ESC, electronic switches, gyro's ect. uses some kind of TTL or CMOS logic as electronic technology, so when running on 4.8V batteries, they are ALL expecting a voltage that should be higher than 2.7V. As far as I remember, 2.7V is in the "forbidden" area for standard logic digital signals, so the electronic, might detect 2.7V as a "0" and not as a "1".
Are you really sure that the output is only 2.7V?
BR,
Tom
