Well yes i do know that the BBB is a 3.3v with a 4-6 mA output. Therefore I have used the following configuration:
* TRIGGER P8_12 gpio1[12] GPIO44 out pulldown Mode: 7 * ECHO P8_11 gpio1[13] GPIO45 in pulldown Mode: 7 *** with R 1KOhm * GND P9_1 or P9_2 GND * VCC P9_5 or P9_6 VDD_5V(from BBB) but am I right ?
