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.

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. It’s convenient to use the onboard antenna for direct line of sight

signals, where the environment conditions are clear for satellite visibility and location estimation. It’s

recommended to use the passive onboard antenna for the satellite signals with signal-noise-ratio (SNR) greater

than 40dB. If users would like to validate the satellite performance, please connect external antenna to the

GNSS/BT SMA header shown in Figure 8.

The 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’s backward compatible with Bluetooth 4.0 and 4.1 and has adopted

Bluetooth core versions starting from 1.1 with Bluetooth BR/EDR.

There are three options to power up the HDK with Bluetooth, Bluetooth LE and external buck power supply. The

data transfer is through an onboard antenna or an external antenna with an SMA connector. The SMA connector

SMA5002 could be connected with an external antenna cable for Bluetooth and Bluetooth LE 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 18.
