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 ## Frequently Bought Together - Electronics-Salon Prototype Screw/Terminal Block Shield Board Kit for Arduino MEGA-2560 R3. - ELEGOO MEGA R3 Board ATmega 2560 + USB Cable Compatible with Arduino IDE Projects RoHS Compliant - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/25504680-prototype-screw-terminal-block-shield-board-kit-for-arduino-mega](https://www.desertcart.at/products/25504680-prototype-screw-terminal-block-shield-board-kit-for-arduino-mega) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-10-23*
