2x1.5v to 3.3v Power Supply and Power Management Board for LoRaWAN-MiniDesigned by Low Power Design Lab, Ships from France
Inventory Update : 19th June : This time two male berg strip are not included. What is it? How about powering your 3.3v LoRaWAN-Mini with two 1.5v AAA battery. If interested keep on reading. Its m...Read More…
The template Arduino code can be found in my github profile
After predefined time interval (defined using external timer resistance - R1, R2, R3, R4) the timer will automatically enable the power.

This is just a rough number and my calculation can be wrong. Normally the AAA battery capacity is 1000 mAh. Assuming the system transmit data every 60 mins and it takes 5 secs to complete this operation at an average current of 150 mA (this is a very high number 150 mA is needed while transmitting and that's too for very short time period may be 1 sec) and for the remaining 59.55 mins it takes ~35nA. With this configuration the battery will last for ~200 days (this is worst case it can be more) The calculation is based on average current consumed in 60 mins. Let me know if you think my bases for the calculation is wrong.
Due to low shipping cost and small size of the package the board is partially assembled but contains all components for you to solder. All electronic components are soldered just the mechanical parts are DIY.
