LCM
The LinkIt 2523 HDK supports two types of display topology: MIPI DSI and serial. The MIPI interface provides a
maximum resolution of display of up to 320*320 pixels and it’s a hyper RGB 1.63 inch AMOLED display. The serial
interface is a 240*240 pixel graphical RGB 1.6 inch thin film transistor LCD. The connector CON6102 on the HDK is
reserved for the serial display LCM.
The HDK supports only one display LCM at a time. The capacitive touch screen is enabled on both displays.
The onboard MIPI LCM or CON6102 supports touch panel connected to the I2C interface. The pin definition of the
connectors can be found in Table 13 with the path selection resistor locations shown in Figure 12. Resistors J6101
to J6106 are designed for onboard LCM and serial pin header switching. Table 13 presents jumper settings for
different use case scenarios.
For MIPI LCM display, users should connect the connectors CON501 and CON502 for touch and display functions;
for serial display, the set of CON401 and CON402 should be used.
Jumpers J401 and J402 enable the current sink , and jumpers J201, J202, J203 are reserved for external current sink
IC to power up the serial display backlight. Only one type of backlight source is needed at a time. All descriptions of
backlight source jumpers and path selections are shown in Table 12.

USB
LinkIt 2523 HDK has two USB connectors, 2523 USB see section 4.16.10, “USB 2.0 high speed connector”
and MK20 USB see section 4.16.11, “CMSIS-DAP USB 1.1 full speed connector ”, as shown in Figure 1. The 2523
USB connector is used to flash the LinkIt 2523 HDK with the LinkIt 2523 Flash Tool.
The MK20 USB is for CMSIS-DAP USB and serial port communication and setting up the board as a mass storage
device. The CMSIS-DAP is the debugging user interface for embedded devices. The mass storage is for flashing the
LinkIt 2523 using the SWD interface. The user can drag and drop the LinkIt 2523 binary file and the FreeRTOS
binary file to the HDK operating as a mass storage device to flash the image directly. The serial port also supports
UART2 connectivity on the LinkIt 2523 HDK.
The maximum charging current is 1.5A at 5V DC for the LinkIt 2523 HDK’s internal charger. The USB power source
is passing through the jumper J2001 on the HDK.
4.13.
GNSS (LinkIt 2523G only)
The LinkIt 2523G HDK is equipped with multi-GNSS chip with a built-in multiband onboard antenna with an
operating range of 1.5GHz-2.4GHz. Set the jumper J5003 to receive Bluetooth, Bluetooth Low Energy and GNSS
signal by an onboard antenna or SMA connector. Onboard antenna provides more convenience when users
validate the GNSS function in satellite signal well-received surrounding, which able to locate HDK’s position directly.
Recommend validating this function when satellite signal signal-noise-ratio (SNR) is greater than 40dB at least for
the passive onboard antenna performance limitation. If users would like to validate the satellite performance,
please connect external antenna to GNSS/BT SMA header shown in Figure 6.
LinkIt 2523G HDK supports GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS standards with optimized power
consumption and extended battery life. Onboard antenna and SMA connector path settings are described in
section 4.14, “Bluetooth and Bluetooth Low Energy”.
4.14.
Bluetooth and Bluetooth Low Energy
The LinkIt 2523 HDK supports Bluetooth 4.2 for Bluetooth core specification updates to provide an improved speed
and reliable data transfer. The transfer speed is up to 2.5 times faster and the protocol stack size is smaller.
Bluetooth 4.2 also consumes less power. It is backward compatible with Bluetooth 4.0 and 4.1 and it also adopts
Bluetooth core versions starting from 1.1 with Bluetooth BR/EDR.
There are three options to power up the HDK with Bluetooth, Bluetooth Low Energy and external buck power
supply. The data transfer is through the onboard antenna or an external antenna with an SMA connector. The SMA
connector SMA5002 could be connected with external antenna cable for Bluetooth and Bluetooth Low Energy
signal strength validation.
Some of the jumpers are designed to switch between the RF signal and Bluetooth mode. Details on switching
between the modes are presented in
Table 16 with the jumpers shown in Figure 16.

Debugging
To enable debugging on the LinkIt 2523 HDK, activate the JTAG interface using Easy PinMux Tool. Switch from the
camera operation mode to debugging mode using JTAG interface by replacing the output pins in a range from GPIO
24 to GPIO 28 in Easy PinMux Tool from camera function to JTAG interface. The debugging data can be captured
through the same shared jumpers directly if JTAG setting is activated. To capture log by JTAG formal pin

[1] Please choose one voltage source without built-in output high-speed
discharge function and confirm the voltage drop-down curve to keep long
output voltage drop-down period.
[2] Please choose external LDOs without output high-speed discharge
function, such as Torex XC6210/XC6215/XC6221 series to keep long
output voltage drop-down period (>1ms from 2.7V to 0.5V).
The voltage drop must can't be lower than 3.1V.
Note 52-15:matching value depends on LNA selected
Note 52-16:GPS_VTCXO_SW Note for external active antenna,
