J-Link PLUS Compact
Sold outUSB powered JTAG debug probe supporting a large number of CPU cores.
Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs.
SEGGER J-Link PLUS Compact is used around the world in tens of thousand places for development and production (flash programming) purposes.
Overview
Get the SEGGER J-Link PLUS Compact debug probe: a compact version of the J-Link PLUS. Mounts securely & unobtrusively into development and end user equipment.
Based on 32-bit RISC CPU, it communicates at high speed with supported target CPUs.
Thanks to a small size with two mounting holes, it can be placed into existing equipment housings.
Space can also be reserved for direct-to-PCB mounting.
All major IDEs (Eclipse & GDB-based IDEs) support J-Link debug probes, as does SEGGER Embedded Studio. 500,000 J-Links have been shipped so far, making this probably the most popular debug probe on the market for Arm cores and the de-facto standard.
Further Advantages
The SEGGER J-Link PLUS Compact has a built-in VCOM functionality and integrated licenses for unlimited breakpoints in flash memory, RDI/RDDI and J-Flash. It supports direct download into RAM and flash memory. It has a broad range of supported microcontrollers and CPUs.

This project detects water leak and records the temperature and humidity reading at the time of leak and sends it to the Adafruit cloud.

By popular demand, we are pleased to announce that it’s now possible to buy the Arduino MKR IoT Carrier. Originally forming a key part of the Arduino Oplá IoT Kit, we’ve responded to our community to make the carrier available on its own, thus enabling you to benefit from having a bunch of sensors, actuators, and a display all featured on the one board — making it quicker and easier to take your IoT projects to the next level. Featuring a large set of built-in sensors and actuators as well as a useful color display, the carrier lets you focus on prototyping your IoT ideas right away by saving on the hassle of wiring and soldering these components. The carrier can become a WiFi, LoRa, NB-IoT or GSM-compatible device by seamlessly connecting to any MKR family board. Building a user interface for these boards is easy with the embedded color OLED screen, five capacitive touch buttons, and the five RGB LEDs. The integrated sensors (temperature, humidity, pressure, RGBC light, gesture and proximity) allow you to map the environment around the carrier, and should you need to capture any other data there are over 100 additional Grove sensors that can easily be connected directly to the carrier. Here’s are quick demo of the carrier's capabilities! (Special shout out to Mirko Pacioni and Filo Connesso for creating this demo.) Capture and store all the data locally on an SD card, or connect your MKR family board to the IoT Cloud for real-time data captured, storage, and visualization.
