## Questions & Answers

**Q: Did they ever fix the silk screen errors?  I would not buy it with such a serious defect!**
A: I have bought, assembled and used 3 of these boards (all Ver: 1.1) in the past year, and none of them have any errors in the silk screen.  Perhaps there was a problem earlier that I never saw.  All of the pads for the breakout connections to the headers that plug into the Mega board are correctly identified in the silkscreen using the same reference nomenclature as on the Arduino Mega, and they all are in the correct sequence.  Maybe some were confused by the placement of the screw terminals due to physical space limitations, especially where needed for the break out of the double-row I/O connector.  As a result of getting those 36 pins into a single row, those screw terminals actually wrap around onto the sides of the board.  That in turn forces the breakout pad connections (along with their silk-screened IDs) to be pushed farther toward the other end of the board (especially on the side where the Arduino's digital pins D0 - D21 are located).  That just means that the breakout pads are not immediately adjacent to the Arduino header pins they are connected to, not that they are wrongly marked.  Long story short, if you go by the pin identification silk-screened on the breakout board, all of the actual connections to the Arduino Mega will be correct.

**Q: Does this board have the icsp header on it and enable pass though (e.g. for an ethernet shield?)**
A: Samtec ESQ-103-14-G-D ( Digikey SAM9289-ND -or- Mouser 200-10314GD ) 6 pin header ( 2x3) will connect Arduino Mega to Arduino Ethernet 2 Shield.

**Q: Is there a CAD file of the assembled board available?**
A: I don't know.  I made my own CAD file.

**Q: Do you have any single sided pc boards?**
A: Sorry, no single sided pcb

## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice breakout board for Arduino Mega
*by D***B on October 14, 2024*

I use this board to connect to an Arduino mega when I want to prototype a project. It's a very convenient way to connect to the Mega in an early development stage, where you don't yet have whatever setup you might use for a late prototype or production version. It takes a minute to positively identify some of the terminals, but once accomplished, this board is a valuable tool for a test or prototyping bench.

### ⭐⭐⭐⭐⭐ Works as advertised
*by T***2 on March 14, 2023*

Board does NOT come soldered; this annoyed me at first but it's $17 and solders easily. Pay attention to the screw terminals; they come in blocks of 2 and 3 and snap together but if you're like me and don't lay them all out first, you might end up with a 3-terminal block and a 2-terminal space left :) I bought this board with a package of headers from another vendor; the 6-pin passthrough block others reference did not come with this package but I did get a 6-pin block with the other vendor's package BUT the height of the block was not sufficient for the Ethernet shield to make contact. Take note of this if you need to put an Ethernet shield (or anything with the 6-pin block on it) over this. Easy to fix if you plan ahead.

### ⭐⭐⭐⭐ Takes a bit of assembly and soldering skills, but result is great.
*by L***N on December 26, 2024*

Components are good. The pins on the headers are strong and straight. The packaging by the vender is excellent. The assembly of the screw headers requires a bit of dexterity and attention to detail. The screw headers slide into the adjacent unit to construct the green, long, straight and trustworthy line of screw clamping connectors. They slide/snap to their adjacent partners. There should be no gap between each unit. If there is a gap, then disassemble the joint by sliding them apart and try again. There are two types of green units: two pin and 3 pin units. Each of the three row that you assemble is composed of two of the 2 pin units and the an appropriate number of 3 pin units. Use care and you will have a solid device.
