PIC18F16Q20 Curiosity Nano I3C Target Demo Board

Availability : In Stock Pre order Out of stock

This accessory board was designed for use with Microchip's PIC18F16Q20 Curiosity Nano evaluation board (not included) and is perfectly designed to complement their I3C Multi-Protocol Translator example project [Github]. This application example demonstrates the implementation of an I3C Target in their 8bit PIC microcontroller. As this MCU is an I3C Target-only implementation, the Supernova is a perfect companion for the I3C Controller.


  • All pins are broken out to standard 2.54mm headers.
  • There are headers on the I3C SCL and SDA signals to easily connect your favorite logic analyzer to observe bus traffic.
  • Integrated W25Q64JV SPI Flash Memory for demonstrating I3C-to-SPI protocol translation
  • Integrated rotary potentiometer for analog readings
  • Integrated LEDs for I3C GPIO Expander demo
  • External connection for I2C Target devices
  • External connection for UART interface
