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. ## Frequently Bought Together - Electronics-Salon Screw Terminal Block Breakout Module, for Arduino MEGA-2560 R3. - Arduino Mega 2560 REV3 [A000067] – ATmega2560, 16MHz, 54 Digital I/O, 16 Analog Inputs, 256KB Flash, USB, Compatible with Arduino IDE for Advanced Projects - 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/318091169-electronics-salon-screw-terminal-block-breakout-module-for-arduino-mega](https://www.desertcart.co.th/products/318091169-electronics-salon-screw-terminal-block-breakout-module-for-arduino-mega) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-09-25*
