Hi Joep, Initially, I wanted to let some space to solder/glue/... a module like this one:
- http://cgi.ebay.com/FTDI-UM232R-module-USB-serial-UART-converter-AVR-PIC-/160429940508?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item255a5e9f1c#ht_3339wt_913 - http://www.sparkfun.com/commerce/product_info.php?products_id=198 - http://www.sparkfun.com/commerce/product_info.php?products_id=8165 - http://www.sparkfun.com/commerce/product_info.php?products_id=718 - http://cgi.ebay.com/PC-USB-RS232-Module-Based-TTL-FTDI-FT232BM-BL-Chip-/320508485967?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item4a9fcb614f#ht_2746wt_981 They cost basically the price of your suggested FTDI cable, but may easier to find ? This module costs 5$ on ebay, male connector (weird): - http://cgi.ebay.com/USB-RS232-Module-Board-CP2102-Breakout-/130337003713?cmd=ViewItem&pt=BI_Electrical_Equipment_Tools&hash=item1e58b0d8c1#ht_1128wt_913 I first thought FTDI cable was too much expensive, but they compare quite well with these modules (20$ / cable, . Users could still use their own serial module with adaptations if needed. Do you think all FTDI cable have the same pinout ?
