Vhf Uhf Low power Transceiver VAULT_PCB_Rev1.0

I chanced upon the Dorji modules, which offered a low cost way to build a small VHF or UHF transceiver. According to the site, the DRA818V is a type of compact wireless voice transceiver module based on RFIC RDA1846 andworks in VHF band. It integrates high speed microcontroller, high performance wireless transceiver IC, high power PA, audio process and squelching circuits. It provides standard UARTinterface which users can easily configure appropriate parameters for different applications.

Inspired by this, I decided to create an Eagle library (DORJI) [Rename the file to .lbr], the schematic is VAULT_Sch_Rev1.0. I’ve created a trial PCB in Eagle (click on the picture for full size). See next post for the updated DORJI Library module.

Please note that the module file is yet to be perfected and is included for completeness. Use of this LBR is at your own risk.
