The TapNLink Wi-Fi/NFC module has 3 connectors:
J1 (2x5 in 1.27mm steps) which connects the TapNLink to the debug connector (ARM-
SWD standard) of the target board via a flex cable (in 0.635mm steps).
J3 (1x5 in 2.54mm steps) which connects the TapNLink to the target board using free
wires that need not be grouped in a ribbon cable or with a single end connector. Note
that J3 is a subset of J1.
P1 extension connector which is composed of two rows of contacts (P1A and P1B) with
2mm spacing. This connector is mainly reserved for the addition of expansion cards and
is only briefly described in this document.
The following figure shows (bottom view) the signals connected to J1 and J3:

This connection corresponds to the format specified by ARM for Cortex-M microcontrollers
Vcc 1 ● ● 2 S3PIO/SWDIO (TMS)
Gnd 3 ● ● 4 S3PCLK/SWDCLK (TCK)
Gnd 5 ● ● 6 SWO (TDO)
Not connected 7 ● ● 8 -- (TDI)
Gnd 9 ● ● 10 nRST
Note:
The names in parentheses correspond to the JTAG protocol. In general, it is advisable to
priviledge using SWD over JTAG for Cortex M-based microcontrollers. For any other
microcontroller, use the S3P protocol.
The signals to be connected in SWD or S3P are:
Gnd
Vcc (the target must provide the TapNLink power),
S3PIO/SWDIO, a bi-directional data signal.
S3PCLK/SWDCLK, the clock signal, bi-directional in S3P.
NRST: Reset signal of the target processor. Its connection is optional. It should be
maintained if you want to use the reset command, or if you want to use TapNLink as a
programmer (the reset signal is required in some programming situations).
