Recieved the first batch of PCB's for the prototype. It still uses the teensyLC, and adds a connector for a ESP8216-01 with its own linear regulator for remote telemetry. It plugs in from the back of the board.

The main board also supports the i2c mux and lipo charging circuit to charge the LiPO from USB.

The TOF sensor board also has a RGB addressable LED for use during testing.

There is also a motor controller board.

All of these bards have JST connector footprints, which we may or may not use.
