I use the MCP2221 USB-Serial bridge and add some electronics to give the board more functionality. So it has a connection for a 3.7Li-Ion battery, battery charger, manual pushbutton to turn on\/off the module and also several led\u2019s to indicate the status of the different elements and network connections.
