The module includes a power-on LED indicator, a convenient red reset button, and an ICSP adapter header, all mounted on a dual-layer FR-4 fiberglass PCB for enhanced durability and performance. Note: Arduino MEGA module not included. ## Description Terminal Block Breakout Module - for Arduino MEGA-2560 R3. the item has been soldered and assembled. Terminal block pitch 3.5mm/0.138", wire size range 26AWG to 16AWG, strip length 5mm, screw M2 steel, pin header and cage copper. With power on LED indicating. red reset button on the side. with a ICSP adapter connect header. FR-4 fiber glass PCB, dual copper layers. NOTE: the item not include Arduino Mega module Review: Great product - Great product to make Arduino reliable and easy to install in project. Review: Makes connections so easy! - I wish I'd have known about this years ago, because after so many projects struggling with reliable pin connections, this thing makes life so much easier! I've gone so far as to unsolder the built-in headers on Arduino Megas and soldering screw terminals for more reliable connections -- and this accomplishes the same thing but is much easier. If you happen to blow up your Mega, this also makes it easy to swap in a new one. COST is a big factor as it's expensive, but it's so well worth it to me! It's a very high-quality part as well. CAUTION: It's not always convenient to access the screws of a terminal when the one above it has already been wired -- especially with ferrules as I prefer to use. So you will save time by attaching your wires in an order to allows access to the screws near the bottom before adding wires above them. ## Features - Terminal Block Breakout Module - for Arduino MEGA-2560 R3. the item has been soldered and assembled. - Terminal block pitch 3.5mm/0.138", wire size range 26AWG to 16AWG, strip length 5mm, screw M2 steel, pin header and cage copper. - With power on LED indicating. red reset button on the side. with a ICSP adapter connect header. - FR-4 fiber glass PCB, dual copper layers. - NOTE: the item not include Arduino Mega module ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07H9TJCWN | | Best Sellers Rank | #212,627 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #613 in Crimp Terminals & Kits | | Brand Name | Electronics-Salon | | Centerline Length | 3.5 Millimeters | | Color | Green | | Colour | Green | | Connector Type | Screw | | Connector type | Screw | | Customer Reviews | 4.6 out of 5 stars 225 Reviews | | Item pitch | 3.5 Millimeters | | Manufacturer | Electronics-Salon | | Material | Copper | | Material Type | Copper | | Model | MD-D1236-1 | | Mounting Type | PCB Mount | | Mounting type | PCB Mount | | Number Of Contacts | 1 | | Number Of Poles | 2 | | Number of Items | 1 | | Number of Positions | 12 | | Number of contacts | 1 | | Part Number | MD-D1236-1 | | Pitch | 3.5 Millimeters | ## Product Details - **Connector type:** Screw - **Item pitch:** 3.5 Millimeters - **Material:** Copper - **Mounting type:** PCB Mount - **Number of contacts:** 1 ## Images ![Electronics-Salon Screw Terminal Block Breakout Module, for Arduino MEGA-2560 R3. - Image 1](https://m.media-amazon.com/images/I/811aNsPjDqL.jpg) ![Electronics-Salon Screw Terminal Block Breakout Module, for Arduino MEGA-2560 R3. - Image 2](https://m.media-amazon.com/images/I/8170naAj+tL.jpg) ![Electronics-Salon Screw Terminal Block Breakout Module, for Arduino MEGA-2560 R3. - Image 3](https://m.media-amazon.com/images/I/81VEEmU-5rL.jpg) ![Electronics-Salon Screw Terminal Block Breakout Module, for Arduino MEGA-2560 R3. - Image 4](https://m.media-amazon.com/images/I/81Xdd-GRcIL.jpg) ![Electronics-Salon Screw Terminal Block Breakout Module, for Arduino MEGA-2560 R3. - Image 5](https://m.media-amazon.com/images/I/71qz3HY0cfL.jpg) ## Questions & Answers **Q: what represents tx and rx? Is there a pinout mapping?** A: The terminal block itself only has the numbered pin information on each screw terminal. The Arduino Mega 2560 has 4 UARTs (8 pins) that can be used for external communication. This link might help: https://www.electroschematics.com/7963/arduino-mega-2560-pinout/ **Q: Does this draw power from the Arduino or can a separate 5V be supplied to this board?** A: It draws a very small amount of power (Only for the red LED) from the Arduino Board if you only works with. Also you can connect a external power supply through the dedicated terminals.It offers the same Arduino functionalities, but with a terminal block version. **Q: Why are pins 14-21 and 0-1 red?** A: Outside of the power pins being red, pins 0, 1 &14-21 are for serial communications pins (Tx & Rx) and that's all they can do. **Q: How do you wire external power to this board? most hats have a jumper to select mega power or external power with dedicated power inputs.** A: There are several terminals for 3.3 and 5 volt connections. There are also terminals for GND. You can hook up whichever power you want. If you use the barrel connector the terminals will have Mega power on them. If you use an external supply that will power the Mega. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by R***L on 4 March 2023* Great product to make Arduino reliable and easy to install in project. ### ⭐⭐⭐⭐⭐ Makes connections so easy! *by L***E on 11 September 2025* I wish I'd have known about this years ago, because after so many projects struggling with reliable pin connections, this thing makes life so much easier!
