Hello,
I bought a AIO std board v4.5 to jlcpcb.
I test th
e board with an 12v power supply.
On the board, i measure the voltage on the pin, right for 5v et 12v and 0v for the pin 3.3v.
I surprise because the board has a regulator 7805 for the teensy board.
Do i have to replace the 7805 regulator by a LM7803 regulator ?
If you are saying the board has good 12 volt and 5 volt power and no 3 volt that is normal without the teensy attached. The teensy supplies the 3 volts. 7805 is the correct regulator. Let me know if I am not understanding the problem correctly.
The micro version of the board has 3.3v, standard doesn’t… when u put teensy in IMU will get 3.3v from teensy.
