• 4706 - iCE40: Do we have any recommended LDO for iCE40 devices ?

  We do not have any specific recommended LDO. The VCC for iCE40 devices has a 5% tolerance. It should be easy to find a regulator having a tolerance within 5% for -40°C to +85°C temperature range.

  LVCMOS IOs driving long PCB traces will often show overshoot at a receiver when the IO output current setting is high. When the IO output current setting is low, the waveforms received can be somewhat distorted on a long PCB trace. This is a common ...

  If it’s to connect a sensor like the Nanovesta board close to the HDR-60, I’d recommend using flex cable, the metal layers are much the same work as laying out a PCB except the material used is now flexible mylar instead of FR4 material or others ...
