uPIC46 Development Board

The uPIC46 is a development board designed around the Microchip PIC18F46K22-I/PT microcontroller.
It is intended for hobbyists, students, and professionals who want a versatile platform for learning, prototyping, and industrial communication testing.

• MCU: PIC18F46K22-I/PT (TQFP package)
• Clocking: External crystal oscillator support
• Memory Expansion: Onboard 24LC256 I²C EEPROM
• RTC: DS3231MZ real-time clock
• USB-UART Bridge: For programming and PC communication
• Connectivity:
  • UART, SPI, I²C headers exposed
  • RTS/CTS and other flow-control pins available on headers
  • RS-485 transceiver for half-duplex communication
  • CAN Bus interface via MCP2515 + SN65HVD230
• Reset & Indicators:
  • Reset push button
  • User indicator LEDs
• Headers:
  • Clearly labeled header pins (A1, A2, A3…) with silkscreen reference table on PCB
  • Breakout headers for easy access to MCU I/O pins

• Compact and user-friendly layout
• Industrial interfaces: CAN and RS-485 included
• Silkscreen pinout table on PCB for quick reference
