Correction of the proposal in order to take into account of the MIDI out inverted connector pin 4/5 detected in #30 . [https://easyeda.com/christian.foucher/pedalinomini-3v3-with-6n138-and-bss138-midi-out-pin4-5-now-ok](https://easyeda.com/christian.foucher/pedalinomini-3v3-with-6n138-and-bss138-midi-out-pin4-5-now-ok) 

BSS138 will adapt 3.3V to 5V without trigger effect. For example : - 0V should give you (0/3.3)*5 ≈ 0V - 1V should give you (1/3.3)*5 ≈ 1.51V - 2V...
