3.1 Power Supply
There are three power supply options:
5V from the USB Type-C 3.3V external power supply CR2032 coin cell battery.
Note: The power sources are routed through a set of diodes (D2, D3, and D4) for reverse voltage protection, where the circuit is supplied from the source with the highest voltage.
3.1.1 Coin Cell Insertion
To insert the coin cell, follow these steps: 1. Push the coin cell against positive contact spring of holder (on the back side of the dev board).
Note: The coin cell sits below the positive contact spring (as shown with arrow).

2. Push the coin cell down into the holder
3.1.2 Coin Cell Removal
Use a screwdriver in the position shown in picture below, to gently remove the coin cell from the coin cell holder (as shown with arrow). This is the correct method to remove coin-cell from holder.
Note: Due to tight fit of coin cell in the coin-cell holder, care should be taken prevent damage to the holder.

3.2 Current Measurement
To measure the current, please take off the jumper cap of W1, and connect an ampere-meter between the pins of W1 to monitor the current directly.
Note:
- Do not use the USB connector to power the board during current measurements. Power the board from a coin cell battery, or use an external power supply on the external supply connector J4.
- The current measurements will become unreliable when a serial terminal is connected to the virtual COM port.

3.4 Switch Positions
3.4.1 NFC
The MK01-KIT evaluation board has an NFC antenna FPC connector, which can be
inserted into the Nordic standard NFC antenna.
To connect the NFC circuit to the MK01 series module, toggle the SW2 toggle
switch to the right. If the SW2 toggle switch is toggled to left, P09 and P10
will be enabled as GPIO pins on J2.
3.4.2 DC/DC regulator setup
The MK01 series module uses LDO regulator setup by default. Connect 10uH and
15nH inductors to the module on the MK01-KIT evaluation board through DCC and
DEC4 pins to enable DC/DC regulator setup.
To connect the DC/DC regulator setup circuit to the MK01 series module, push
the SW4 self-locking switch to ON state. If the SW4 self-locking switch is
pushed to OFF state, DCC and DEC4 will be enabled as GPIO pins on J3.

3.4.3 External 32.768 kHz crystal oscillator
The MK01 series module on-chip 32.768kHz RC oscillator provides the standard
accuracy of ±250 ppm.
The MK01-KIT evaluation board connects an external higher accuracy (±20 ppm)
32.768 kHz crystal to the P00 and P01 pins of MK01 series module.
This provides improved protocol timing and helps with radio power consumption
in the system standby doze/deep sleep modes by reducing the time that the Rx
window must be open.
To connect the optional external 32.76kHz crystal oscillator circuit to the
MK01 series module, push the SW5 self-locking switch to ON state. If the SW5
self-locking switch is pushed to OFF state, P00 and P01 will be enabled as
GPIO pins on J3.
3.5 Jumper Positions
3.6 USB to UART
MK01-KIT evaluation board allows the MK01 series module to physically connect to a PC via the supplied USB Type-C cable for development purposes. The evaluation board provides USB-to-UART port conversion through a CP2102 bridge.
GPIO – UART
P14 – RTS
P06 – TX
P16 – CTS
P08 – RX
