John - As far as serial versus USB, you will find that majority of potential users prefer USB (laptops, etc.).
Many of the "new Arduino style" boards have UART for serial (5-line implementation) with usage of USB-UART cables. Sparkfun is one group that sells these (their version of the standard FTDI cable offering at $20). https://www.sparkfun.com/products/9718?gclid=COTW15yr8McCFYQ_aQodVQAI4Q The 18-pin daughterboard you referenced uses the FTDI FT232Rx chip (L version is 28-pin SSOP; Q version is 32-pin QFN) http://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT232R.pdf I like the FTDI FT-232R --- due to its ability to be programmed (invert the serial line, etc.). Saves chips for those needs. greg -- You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
