Repair Sanguinololu board
- I've got the boards (a sanguinololu v1.2 with 4 drivers and one opto limit switch).
- Heard from Hipster that the problem was with the temperature measurement. It looks as though the ADC inputs are damaged (the design offers no protection, the microcontroller inputs are directly exposed to external connections) as they're being forced to 2.5V by the micro. Replacement micro ordered. A workaround is possible (use spare ADC inputs) but the micro is cheap.--Artag 06:49, 8 July 2012 (UTC)
