MCP-2025-500? #13

Open Aquillacomputingsystem opened 1 year ago

Aquillacomputingsystem commented 1 year ago

Having some issues sourcing 330 in Aus. I can get a 500. The only difference is it's 5v out the regulator instead of 3.3 If I got the 5v do you have any recommended Cap or resistors? Any help would be appreciated

The MCP2003 will also work, just follow the typical application notes.

For the 5v regulator version, the typical application notes in the datasheet contain the recommended cap/resistor values - just check that the voltage levels for the rx/tx lines are acceptable for your microcontroller, the esp32 is not 5v tolerant afaik.
