mDot Pinout Design Notes
Refer to the mechanical drawing for your model for pin locations.
All pins that go to connectors are directly connected to the processor.
Reset is the only pin with pull up.
I/O is 5V tolerant.
mDots allow you to program pins depending on your application:
Serial: Available out of the box. See Serial Pinout Notes for details.
mbed: Designed with the mbed STM32F411 RET 64-pin processor, this option provides the most flexibility.
For more information about processor capabilities, see the STM32F411 RET datasheet.
Note: To program the mDot, you need an mDot model with programming header., model MTDOT-xx-X1P-SMA
Serial Pinout Notes
Out of the box, these pins are available for serial applications. Refer to the mechanical drawing for your model for
pin locations.

Throughput Rates
Theoretical maximum speeds for LoRa mode with ACKs off are:
Using spreading factor 7 at 125kHz, the throughput rate is 5470 bps (5.47 kbps).
Range
Variables effecting the range include TX power, antenna gain, RX sensitivity, fade margin, earth's curvature. Use
the following formula to calculate the maximum range:
