    The Certified Projects Directory makes it easy to find certified open source hardware.

  5. DE000077 - certification.oshwa.org

    May 28, 2020 · Logic Level Shifter (bidirectional and suitable for I2C) to connect systems with different voltage levels, e.g. a 3.3V sensor to a 5V microcontroller.

  6. US002405 - certification.oshwa.org

    Aug 2, 2023 · It will let you use the 3V power and logic from your 5V device (like an RPi), and boost/shift it up to 5V. This breakout uses a 4-pin Sparkfun Qwiic-compatible connector called STEMMA QT, …

  7. US001031 - certification.oshwa.org

    This project is intended to provide RS-485 level shifting to Adafruit Feather development boards using the standard Feather footprint.

  8. US002611 - certification.oshwa.org

    Feb 22, 2024 · It runs on 4FSK (4-frequency shift keying), which means that it separates tones into 4 separate frequencies. Upon this, it uses the Horus Binary v2 system, which is a relatively modern …

  9. US000575 - OSHWA

    May 9, 2020 · Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level …
