Surgery on the Mini60 Begins…

I started the bluetooth module retrofit of the Mini60 Antenna Analyzer today. First step is to configure the BC04-B Bluetooth module as the only baud rate supported is 57600. To do this I needed to buy a USB to TTL module from Ebay:


Instructions for programming the new baud rate and wiring the module can be found here: The painful part is making the connections to the USB to TTL converter. I had to solder four small solid wires to the necessary pads which is tricky as the pads are small and its hard to keep everything positioned. I needed a set of third hands, magnifiers and pair of tweezers but I got them on. The programming went as advertised. Once programmed I removed the wires and prepared to install on the Mini60.
