Is there some “for dummies” schematic how to connect this module to Arduino? I read that you need to add some parts to to connect 5V Arduino pins to 3.3V Bluetooth module. Could You tell me what parts and their values? I don’t want to damage the module. Can SeedStudio also add this info to datasheet? This would help many people.
The Bluetooth module is originally designed working in 3.3v.(compatible with seeeduino )
However Arduino is working in 5v, so they are not compatible.
Anyway I tried to make an level transform circuit (not tested yet )
