2. Soldering the headers
Before using your click™ board, make sure
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.

1. Introduction
USB SPI click™ is an accessory board in
mikroBUS™ form factor. It’s a compact
and easy solution for adding SPI serial
communication via USB cable. It features
MCP2210 USB-to-SPI protocol converter
with GPIO as well as USB MINI B connector.
USB SPI click™ communicates with target
board via SPI interface as a master device.
The board is designed to use 3.3V or 5V
power supply. It has a LED diode (GREEN)
that indicates the presence of power supply.

Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder
the pins carefully.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into the desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all the pins are aligned
correctly, push the board all the way
into the socket.
4. Essential features
USB SPI click™ with its MCP2210 IC gives
additional SPI serial communication via
USB cable. The MCP2210 IC contains 256
Bytes of user EEPROM, 128 Byte buer to
handle data (64 byte transmit and 64-byte
receive) and nine general purpose I/O pins.
The board contains 12 MHz crystal oscillator
which provides external clock waveform for
MCP2210 IC as well as a LED diode which
indicates SPI trac.

There is one zero-ohm SMD jumper J1 which
is used to select whether 3.3V or 5V power
supply is used. Jumper J1 is soldered in 3.3V
position by default.
