Use FiPy without the expansion board
We are asking that can we configure fipy without using the expansion board ? , when we connect it to the laptop via USB To TTL, we get " No pycom boads found on usb " on Atom..

@NB_IOT using a USB to TTL connector is possible. You should take care that:
a) the adapter can supply sufficient power to the FiPy.
b) the TX/RX levels are set to 3.3 V
Looking at the picture I cannot tell whether the connections are right. The FiPy, when just powered, should show the blue heartbeat LED every 4 seconds. if not, it's probably not powered, or the firmware is damaged.
Can you use a simple terminal emulator like Putty to test the connection.
