Samsung ARTIK 055s SoM SIP-KITNXH002 - Development Board Samsung ARTIK 055s Starter Kit / SIP-KITNXH002 development board speeds the development of the Internet of Things (IoT) projects. The ARTIK 055s Starter Kit has built-in robust security, compactness, and connectivity. A dedicated 5-12VDC power supply (not included) or a micro-USB connector deliver power to the kit. The ARTIK 055s module is included in the starter kit, mounted to an interposer board, as well as an ARTIK starter board. ARTIK 055s development kit contains ARTIK 055s module and embedded evaluation board. Samsung ARTIK 055s module is a highly integrated module for secure Internet of Things (IoT) devices that require Wi-Fi connectivity. It is based on an ARM Cortex R4 core with on-module RAM and flash memory, a complete 2.4GHz Wi-Fi subsystem with on-module antenna, an independent security subsystem, PUF-based module authentication and a large complement of standard I/O interfaces.

8051 Development Board (Made in India) The 8051 Development Board is equipped with an Atmel AT89S52 Microcontroller IC and an RS232 chip. It features a DIP 40 Pin IC Socket for easy insertion and removal of chips, and can support a range of chips including AT89S51, AT89S52, P89V51RD2, and 8052. The board is built with a high-quality FR-4 (1.6 mm) PCB.In addition, the board has an on-board RS232 circuit that enables easy communication with a PC and other RS232 serial devices such as GPS modules, GSM modems, and RFID. It also has an extra Vcc bus (5V and 12V) and GND bus for power supply to external peripherals.The 8051 board has an on-board bridge rectifier, allowing it to accept both AC and DC input voltages for power supply. It is also equipped with a 5mm Power Plug-in DC Jack, a Power ON-OFF switch, a 5V regulator (LM7805) circuit, and a power indication RED LED.Other features of the board include an on-board reset button, a quartz crystal 11.05892 MHz, a GREEN USER LED at Pin P2.0, an input user switch Pin P3.3, and an input external interrupt switch (INT1) at P3.3 through jumper JP2. Port extensions are provided for all PORT with detailed labeling for easy identification of pins, and external pull-up resistors are included for port use.The development board also has an on-board ISP connector for loading HEX files into microcontrollers such as AT89S51/52. It has four 3mm mounting holes for easy mounting. read more : How to Choose a Microcontroller Applications Embedded Systems Robotics Internet of Things (IoT) Industrial Automation Package includes 1x 8051 Development Board (Made in India) Specifications: Operating voltage 9 - 18 V Processor Socket ‎DIP 40-Pin Flash Memory 8 KB Processor Speed ‎11.05 MHz Number of Ports 4 Dimensions 12cm x 6.4cm
