- Schematic
- Pin functions (these functions are available via the SP/CE connector, and as unpopulated headers on the breakout):
- GND - Ground (this is pin 1 on the SP/CE connector, nearest the SIM card holder)
- PWRKEY - Power key pin, needs to be toggled low and then high to power up the module
- RX - UART input to breakout
- RESET - Reset pin, pull high to keep breakout active
- NETLIGHT - Output from LTE module, for blinking a LED when there is a network connection. It has a max output drive of 7mA and if you wire an external LED to this pin it should have a series resistor.
- TX - UART output from the breakout
- VDDIO - IO voltage input, 3.0 - 3.6V recommended for reliable IO. Low current consumption.
- VDD - 3.7V - 6.0V power input to the breakout (scroll down for current consumption info)

- VDD current consumption info from our testing:
- Idle: 17mA
- Sleep modes: 0.12mA - 1.63mA
- Peak current consumption when transmitting: 700mA (the peak current is only reached for a brief moment, and the 440uF of capacitors on the breakout help to smooth the peaks)
- The average currents we saw when actively using the module were in the 50mA - 100mA range.
- The LTE module has quite a sensitive undervoltage circuit, so if your breakout keeps turning off randomly or when you try and do anything with it check your power supply and wiring is up to the task!
