3.6 USB-UART Serial Converter (U101)

The PIC32-BZ6 Curiosity Board has an on-board MCP2200 that acts as a USB-to-UART serial converter (U101) with hardware flow control support. It enables the user to connect to the Host PC through the USB Type-C® connector (J100). MCP2200 supports UART baud rates from 300–1000 kbps. Voltage level translators are provided on signals between the MCP2200 and PIC32WM-BZ6204UE Module for supporting target voltage from 1.9–3.6V when powered externally.

Note:
  1. PB4 is shared between Graphic interface data line and UART CTS. By default, the PB4 is connected to the Graphic Interface (J910). To use UART_CTS, the user must populate resistor (R602).
