It has high-end security features included to achieve best in clas security with an ARM
CryptoCEll cryptographic system on chip and a full AES 128-bit encryption suite.
Holyiot-17120 module use the Serial Wire Debug(SWD port ), the module which layout the
SWDIO, SWCLK, VDD, GND for debug and flash your own firmware, more info about the SWD,
please visit https://www.silabs.com/community/mcu/32-bit/knowledge-
base.entry.html/2014/10/21/serial_wire_debugs-qKCT
You can using the Jlink or Jtag for programmer.
It supports the standard Nordic Software Development Tool-chain using Segger Embedded
Studio, Keil, IAR and GCC. More info please visit
http://infocenter.nordicsemi.com/index.jsp?topic=/com.nordic.infocenter.nrf52/dita/nrf52/develo
pment/nrf52_dev_kit.html&cp=1_1
This module support Bluetooth 5, Bluetooth Low Energy,Bluetooth mesh,Thread,
802.15.4,ANT, 2.4GHz proprietary. So we can use different protocols for different situations.
Software Development Kit
Nordic Semiconductor's Software Development Kits (SDK) are your starting point for software
development on the nRF51 and nRF52 Series. It contains source code libraries and example
applications covering wireless functions, libraries for all peripherals, bootloaders, wired and
OTA FW upgrades, RTOS examples, serialization libraries.
More info please visit http://www.nordicsemi.com/eng/Products/nRF52840-DK
You can also download the SDK for coding development .

5. Absolute maximum ratings
www.holyiot.com info@holyiot.com
Soldering Temperature-Time Profile for Re-Flow Soldering. Maximum number of cycles for re-
flow is 2. No opposite side re-flow is allowed due to module weight.
Maximum ratings are the extreme limits to which the chip can be exposed for a limited amount
of time without permanently damaging it. Exposure to absolute maximum ratings for prolonged
periods of time may affect the reliability of the device.
Absolute maximum ratings:
