Test Point Matrix

In order to create a custom Pogo-Pin Cassette for the printed circuit board of a Device Under Test (DUT), a Test Point Matrix (.xlsx template) should be established, to specify how the PLT-300A test probe and signal rails should be connected to the test points in the cassette.

Sample PLT-300A Test Point Matrix

Test Point	PLT-300A Test Probe and Signal Rails	DUT Net name	Notes
TP1	GND1	AGND
TP2	GND2	GND
TP3	GND3	GND
TP4	3V3OUT; DATP03	VCC
TP5	SWD_NRST	nRST
TP6	SWD_SWDIO	SWDIO
TP7	SWD_SWCLK	SWCLK
TP8	DATP00	BAT_SENSE
TP9	UART0_TXD	MCU_RxD	Add opto-coupler
TP10	UART0_RXD	MCU_TxD	Add opto-coupler
TP11	DDTP02	BOOT0
TP12	DDTP03	BOOT1
TP13	RATP00	GPIO26_ADC0
TP14	RATP01	GPIO27_ADC1
