Built on a durable FR-4 fiberglass PCB with dual copper layers and housed in fireproof nylon, it supports multiple DIN rail sizes (15/32/35mm) and can be easily converted for panel mounting. Ideal for professionals seeking reliable, clean, and scalable industrial control prototyping. ## Description Product description DIN Rail Mount Pinout Breakout Terminal Block Module for Arduino MEGA-2560 R3 / Due DIN Rail Mount Screw Terminal Block Adapter Module for Arduino MEGA-2560 R3 / DUE, with the adapter module, you can easily extend Arduino projects to industrial control applications. Pitch 3.81mm/0.15" screw terminal block. Terminal block: wire range 26-16AWG, strip length 5mm, Metric M2 slotted screw. FR-4 fiber glass PCB, dual copper layers. PCB Dimensions: 150mm x 72.5mm(W x L). Module Dimensions: 153mm x 87mm x 45mm (W x L x H). High quality Taiwan DINKLE Fireproof nylon material DIN rail mount carrier, can support width 35mm / 32mm / 15mm rail, and the carrier can be taken apart for panel mount use. Note: the item not include Arduino-Mage module and iron rail. Review: It's what you've been looking for. - I bought one of these sized for an UNO a couple of years ago and was so pleased with it that I decided to get one for my MEGA. Craftsmanship is evident the moment you unpack it, and it is so very nice to be able to attach my micro to a DIN rail for those applications where mounting must be done in an industrial enclosure. I know having the micro mounted upside down takes some getting used to, but it doesn't matter since the screw terminal blocks on this mount are all right side up and you have access to all I/O pins. One person mentioned the ICSP pins not being extended to this mount and it's true; however, if you are in need of those pins you can load the example sketch ArduinoISP and use it to change the programming pins to three unused digital pins giving you access to them on this mount. Bottom line: if you want your Arduino MEGA mounted on a DIN rail, this is the most straight forward, albeit not the least expensive, approach you are likely to find. Plastic mounts and two-sided tape will cost less than this, but you will not have screw terminals to make your job easier. Using tape will result in a somewhat wobbly installation that may or may not hold long-term. If you're using DIN rail you are probably doing something important that will benefit from a quality mount. This is it...!! Review: Who needs to create awesome prototypes faster - This break out board can save you bunches of time if you do small runs of prototyping. I doubt if I am alone in finding oui I soldered 6 wires in the wrong place. Sure you can make the same mistake using this break our board but your end product looks more professional. ## Features - DIN Rail Mount Screw Terminal Block Adapter Module for Arduino MEGA-2560 R3 / DUE, with the adapter module, you can easily extend Arduino projects to industrial control applications. - Pitch 3.81mm/0.15" screw terminal block.
