This basic circuit can be the building block for other system designs. Some of the ideas we came up with are the following:

1. Wireless Data Transmitter Sensor Nodes: The system can be collecting data any sensor and transmit it wirelesslly. The system will implement the low power modes of the MAX32625 to extend the battery life. The best wireless solution to incorporate are low power transceiver devices, like a BLE or LoRa.  

2. Smart Data Logger: The MAX32625PICO can monitor events in low power mode from any senor via the PMU (Periferal Management Unit).  A key event will triggering the logging of valuable data or the reprogram of the mission. The characteristics measured can be altitude, humidity, motion, and/or time.

3. iButton data logger Setup, Backup and Smart battery management: The MAX32625PICO can be programmed to deploy an iButton mission, which is essentially the programming required for the iButton to collect data at a determined interval. The microcontoller can maximize the battery of the iButton, by enabling and disabling the internal RTC clock of the iButton and only enable when the collection is required.  This design can be enhanced by a wireless interface as mentioned above.
