Direction
- Module ground
Positive reference for module power supply, voltage range: 3.0 to
-
3.6 VDC
Used to indicate module operating status; user wakes up external
Output MCU and outputs low during power-up self-test initialization;
(can be left hanging)
Output TTL serial output, connected to the external RXD input pin.
Input TTL serial input, connected to the external TXD output pin.
In conjunction with M0, determines the 4 modes of operation of
Input (very
