clicker for CEC1702 is a compact development board with
two mikroBUS™ sockets for click board™ connectivity.
With more than 270 click boards™ so far, you can combine
dierent functionalities and create without limitations.
The board carries the CEC1702, a 32-bit ARM® Cortex™
-M4 Processor Core, with strong cryptographic support. It
also contains two indication LEDs, two general purpose
buttons, a reset button, an on/o switch, a li-polymer
battery connector, a Micro USB connector.
A mikroProg connector and a 2x26 pinout for interfacing
with external electronics are also provided.
The mikroBUS™ connector consists of two 1x8 female
headers with SPI, I 2C, UART, RST, PWM, Analog and
Interrupt lines as well as 3.3V, 5V and GND power lines.
Clicker 2 for CEC1702 for CEC1702 board can be powered
over a USB cable.

1. Power supply
You can supply power to the board with a Mini
USB cable provided in the package. On-board
voltage regulators provide the appropriate
voltage levels to each component on the
board. Power LED (GREEN) will indicate the
presence of power supply.
You can also power the board using a Li-Polymer
battery, via on-board battery connector. On-board
battery charger circuit enables you to charge the battery
over USB connection. LED diode (RED) will indicate
when battery is charging. Charging current is ~300mA

make sure to load the target HEX le using the Load button.
Then click the Write button to begin programming.
Click the Erase button to clear the microcontroller memory.

Before attaching
the programming
connector, you
have to solder the
provided 2x5 male
header to the JTAG
(CN3) pads.

Two LEDs, two buttons
and a reset button
4. Buttons and LEDs
The board also contains a 01 reset button
and a pair of 02 buttons and 03 LEDs,
as well as an ON/OFF switch. The
Reset button is used to
manually reset the
microcontroller—
it generates
a low voltage
level on the
microcontroller’s reset
pin. LEDs can be used
for visual indication of
the logic state on two pins
(GPIO156 and GPIO157). An
active LED indicates that a logic high
(1) is present on the pin. Pressing any
of the two buttons can change the logic
state of the microcontroller pins (GPIO032
and GPIO113)) from logic high (1) to logic low
(0). In addition to the onboard ON/OFF switch,
two pads (EXT and PSW) allow you to connect

The CEC1702 microcontroller is equipped
with an internal 32kHZ oscillator that
provides a stable clock signal. The board
also contains a 32kHZ crystal oscillator.

The use of
crystal in all other
schematics is
implied even if it
is purposely left
