Hello everybody! I'm new to electronics and would like to ask for help creating a PCB circuit schematic for a personal project.
I want to use an ESP32-C3 as the main microcontroller and an MPU-9250 sensor to measure acceleration, gyroscope and magnetic field in real time.
Communication between the two will be done via I2C (SDA/SCL), and I intend to power the circuit with a 3.7V LiPo battery, with a wireless charging module incorporated into the PCB. I know it may be necessary to use a voltage regulator for 3.3V as the ESP32-C3 and sensor work at that level.
I wish the schematic included:
Decoupling capacitors for the ESP32-C3 and the MPU-9250 sensor;
Pull-up resistors on the I2C bus (typical values ??of 4.7kΩ);
Header with TX, RX, GND and 3.3V pins to be able to program the ESP32-C3 via UART;
Basic circuit to charge the battery by induction (wireless), with protection if possible;
Good design practices (separate power and data tracks, minimize noise on I2C, etc.).
I have little experience with schematics or PCBs, so I would greatly appreciate any guidance, example or file you can provide me (for example for EasyEDA or KiCad).
Thank you very much in advance!
