2. Soldering the headers
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.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
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.
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.
4. Essential features
The chip supports full-speed USB (12 Mb/s),
I
2
C with up to 400 kHz clock rates and UART
baud rates between 300 and 115200.
The USB has a 128-byte Buer (64-Byte
Transmit and 64-byte Receive) supporting
data throughput at any of those baud rates.
The I
2
C interface supports up to 65,535-byte
long Reads/Writes Blocks. The board is also
supported with Microchip’s conguration
utility and drivers for Linux, Mac, Windows
and Android.

USB I
2
C click carries an MCP2221 USB-
to-UART/I
2
C protocol converter. The
board communicates with the target
microcontroller through mikroBUS
™
UART
(RX, TX) or I2C (SCL, SDA) interfaces. In
addition to mikroBUS
™
, the edges of the
board are lined with additional GPIO (GP0-
GP3) and I
2
C pins (SCL, SDA plus VCC and
GND). It can operate on 3.3V or 5V logic
levels.
