3.5.3 Hardware Modifications

The on-board debugger is connected to the PIC16F18446 by default. These connections must be removed before any external microcontroller can be programmed or debugged. Cut the GPIO straps shown in the figure below with a sharp tool to disconnect the PIC16F18446 from the on-board debugger.

Figure 3-9. Programming and Debugging Connections to Debugger
Info: Cutting the connections to the debugger will disable programming, debugging, and data streaming from the PIC16F18446 mounted on the board.
Tip: Solder in 0Ω resistors across the footprints or short-circuit them with solder to reconnect the signals between the on-board debugger and the PIC16F18446.
