Converters

Speed up your embedded and hardware designs with converter schematic modules for KiCAD, professionally designed for reliability and reusability. These ready-to-integrate blocks handle common electrical interface challenges such as voltage shifting, protocol translation, and USB bridging.

Each module includes:

  • Verified converter ICs (e.g. CH340, MAX485, TXS0108E, etc.)
  • Proper passive components: resistors, capacitors, ferrites
  • ESD/TVS protection where applicable
  • Clean, labeled schematics for immediate use
  • Compatible footprints and clearly defined I/O net names
  • Optional jumper/select pins for configuration

Examples of included modules:

  • ✅ CH340 – USB to 3.3V UART Converter
  • ✅ 3.3V to 5V Logic Level Converter (Bidirectional)
  • ✅ RS485 to UART Converter (with A/B line protection)
  • ✅ I2C Voltage Translator Modules (e.g., PCA9306)
  • ✅ CAN Transceivers (e.g., SN65HVD230)
  • ✅ SPI/UART/I2C signal isolators
  • ✅ TXB0104 / TXS0108 Logic Translators

These modules are ideal for:

  • Embedded system communication interfaces
  • Interfacing 5V peripherals with 3.3V MCUs
  • Industrial and RS485-based communication designs
  • Makers and professionals building USB bridges or logic-safe systems
