Hello Peter, Thank you. I hadn't considered semiconductor relays but will do so now. Whilst the 2560 does have the extra UARTs, part of the appeal of the 1284p is that it is still available in a DIP package. For a DAC I was thinking of an MCP4801/4011/4821 (or the dual 4802) which would give the option of 8, 10 or 12 bit for the same footprint.
Do you have any views on UART RF modules? I have had success with AmForth over RF before but unfortunately the company that made the modules is no longer in that business. Consequently I am looking for a replacement module for the 1284p board, ideally one with hardware encryption (as the old one did). Tristan On 10May17 08:21, Peter C.
