1.  Project


2.  The purpose of this lab is to design an esp 32 module using eagle creating the schematic and layout. Then once the board is recieved soldering all nessasary smd devices to power module. Then the module will be attached to a 3.7 lipo batter to provide voltage to esp and a circuit will be created to power the lipo battery using a power regulator, charging module and switches. Lastly the esp 32 pcb will be tested to verify functionality.

3. Materials and Methods

ESP32
lipo 3.7 battery
charging circuit


4. Results


Figure 1.  Task 1 soldered board will all nessasay devices.



Figure 2. Task 2 device is being powered by the 3.7 lipo batttery.



Figure 3. Battery multimeter reading before when uncharged then added switches flipped and allowed to charge voltage. (task 3)


Figure 4. Entire charging circuit connected the PBC


Figure 5. Light turns on when switches allow battery to be connected to charging circuit allowing charging to occur.
 





Figure 6. Code used to demonstrate task 4 the functionality of the sensor board and the display. (task4)


Figure 7. Demonstration of PCB (not yet achieved) 

5. Discussion
The lab was good overall there was some stuggles with soldering and functionality of the power supply. These were remidied with resoldering carefully and makeing sure things werent being shorted. The Lab was challanging at times but good to know the knowledge here and the lipo battery was a cool modification.
