Hello everyone, I have made a schematic for this project, I need your help with this project of mine. It is for a fitness device I am trying to just experiment with. I am trying to follow this schematic as close as possible- https://dl.espressif.com/dl/schematics/esp32-pico-kit-v4_schematic.pdf

I have shared a PDF below showing what I have done till now

I am not very sure of wether I have done the right things with my schematic, please do let me know if I've gone wrong somewhere. I will definitely explain if you have any questions.

The components I have chosen are-

1) ESP32 PICO D4 (Microcontroller) -https://www.mouser.com/datasheet/2/891/esp32_pico_d4_datasheet_en-1365829.pdf

2) XC6210B332MR (3.3v LDO) - https://www.torexsemi.com/file/xc6210/XC6210.pdf

3) MCP73831T-2ACI/OT (Li-Ion Charging IC) - https://www.mouser.com/datasheet/2/268/20001984g-846362.pdf

4) ICM-20948 (9 axis IMU) - https://product.tdk.com/system/file...l/imu/data_sheet/ds-000189-icm-20948-v1.3.pdf

5) 211964-0001 (Ceramic Antenna) - https://www.mouser.com/datasheet/2/276/2/2119640001_ANTENNAS-1912770.pdf

I also I need help with the antenna, I am not sure wether I have done it right, and chosen the right one. There might be some more help that I need with this, I am just doing this as a hobby, I have no professional experience in building electronics. Please do let me know if there are any changes that need to be made to this. Thank you for your help.
