Target Connection Circuitry

Figure: Standard Connection To Target Circuitry shows the interconnections of the MPLAB PICkit 4 In-Circuit Debugger to the connector on the target board. The diagram also shows the wiring from the connector to a device on the target PCB. A pull-up resistor (usually around 10-50 kΩ) is recommended to be connected from the Vpp/MCLR line to Vdd so that the line may be strobed low to reset the device.
