I would like a pcb similar to the long cricket designed that used a ublox8 or greater with a chip antenna. In addition to the long cricket specs I would like to have onboard 3.7v battery charging circuitry.
Here is the starting point.

The device needs to be low power and only rely on chip antennas for both Lora and gps, there can be no external patch antennas for my use case.
I had purchased this and it no longer works so if undertaking this gig can you make sure that the Lora chip and the USB boot loader are quality parts.
