With the breakout board, you can easily extend Teensy 4.1 projects to industrial control, home automation or other applications. With 112 DIY solder pads on board, pitch 2.54mm, hole 0.8mm, you can use these pads to install soldered some electronic components for you need. Terminal block: Pitch 3.81mm/0.15", wire range 26-16AWG, strip length 5mm, Metric M2 slotted screw. FR-4 fiberglass dual copper layers PCB. Taiwan High quality fireproof nylon material mount carrier(not China low quality carrier). Packing list: 1x Breakout board module, 2x M3x10mm wood screws, 2x 24pin pitch 2.54mm/0.1" pin header, 1x 5pin pitch 2.54mm/0.1" pin header. Note: the item not include Teensy 4.1 board. Review: Agree: great product and very fair price - The Teensy 4.1 screw terminal breakout module is well built, and perfectly designed for my needs. The screws are strong for proper tightening, big enough for torquing, widely spaced for practical connection, and seem to stand up to repeated use. The wire slots are big enough to accept reasonable-size wire (no issues) or even multiple wires (such as adding external pull-up resistors). Pin labels are very clear (no mistaking which terminal is which) and can be read from the side and from the top. I have not used the breadboarding area (plated-through holes) but I plan to. Ordered more of these! The Teensy is exceptionally useful with this clever device. Well done! Review: Is verry convenient, fits great. - I am using this on a robot project and it is a really nice way to connect wires neatly. It is also nice that I know the wires are secured tightly unlike older versions of my robot. The screw terminals seem to work very well and be high quality ## Features - Terminal Block Breakout Board Module for Teensy 4.1, Screw Mount Version.

The screw terminals seem to work very well and be high quality ### ⭐⭐⭐⭐⭐ The best screw terminal breakout module for Teensy 4.1 *by L***O on July 16, 2025* The best screw terminal breakout module for Teensy 4.1. It's sturdy, comes pre-assembled, and you only need to solder the microcontroller pins. It has spaces to connect other electronic components. The pins are clearly marked. And what I like most is that each and every one of the microcontroller pins has a screw socket. And of course, it can be fixed to a surface with screws. ## Frequently Bought Together - Terminal Block Breakout Board Module for Teensy 4.1, Screw Mount Version - PJRC Teensy 4.1 ARM Cortex-M7 Processor at 600MHz with a NXP iMXRT1062 (Without pins) - PJRC Teensy 4.1 ARM Cortex-M7 NXP iMXRT1062 Microcontroller Development Board + Ethernet Kit --- ## 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.co.uk/products/285371876-terminal-block-breakout-board-module-for-teensy-4-1-screw](https://www.desertcart.co.uk/products/285371876-terminal-block-breakout-board-module-for-teensy-4-1-screw) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-27*
