Das Oszi 3.5MM Uart
This procedure has been documented in a way that someone who has very little experience with soldering or board modification should be able to accomplish the mod. In addition the parts chosen have been selected due to the availability, ease of use, and cost. Of course there are better ways, more robust solutions, and ones that are not so "hackish".
Note: If you use a 2.5mm stereo socket instead of the 3.5mm one, you can use the many "Motorola T191" and compatible cables as they are used with OsmocomBB and a varity of other Osmocom projects. The cables are also often available cheaper than the 3.5mm cable from Digikey linked below.
- quantity 1 - usb->rs-232 with audio jack
- quantity 1 - through hole audio jack
- quantity 2 - 7in 3-pin Fan Power Extension Cable
NOTE: Sparkfun.com has a good selection of compatible parts
