Level Converter

Other Retired Products
1

I am trying to find documentation and/or Schematic for this Old Sparkfun Level Converter (no Part number on Bags). :frowning:

Reason I asking I don’t remember if these are BiDirectional. If I remember there was some problematic Level Converters back in early 2011 - 2014.

I am OK with purchasing new version of these but the current Sparkfun Level Converters appear to be out of stock.

If I remember Correctly this is for I2c.

The info for that board is at https://www.sparkfun.com/products/retired/11978 The TX path is bidirectional (the same MOSFET level shifter that is on the current board). The RX path is a simple resistor divider so it is unidirectional.
