PCB tracing, schematic checking

It's a small gps tracker with gsm modem. It contains gnss module l76, a9 gsm modem, attiny861, battery charger. They are connected with uard and i2c bus.

You have to check

0) That everything is correct in general.

1) Schematic - that everything is done correctly, including resistors values, capacitances, connections, etc

2) That components matches by voltages and currents. Some of them have different vcc and it makes their direct interconnection impossible.

2) Trace a pcb according to general rules and datasheets recommendations, check selected components, maybe they were wrong

3) Select matching network elements (some working default) for antenna

It's a KiCad project, can be checkouted from here - [login to view URL]

It's a bit complicated, I'm opened fr any questions.
