With an input range of 4.5-12V and adjustable frequency settings, this module allows for precise control in various electronic projects. Its robust output capabilities and easy installation make it an essential tool for anyone looking to enhance their circuit designs. ## Description 2 Pack555 Timer modules make it simple to connect, adjust, and experiment with these versatile ICs. The jumpers select frequency bands - J1 being the lowest and J1 being the highest. The two pots control frequency and duty cycle (though these are not intependent) so the adjustment of these pots determines the actual output frequency within the selected band. The maximum frequency we have measured (with a Saleae logic analyzer) is ~302kHz, and the minimum around 0.56Hz (this depends on how light of a touch you have when turning the pots). These measurements were taken @ 5V supply voltage ## Features - 4.5-12V Input - 4.2-11.4V Output - Max. output current 15mA@5V 35mA@12V - Adjustable frequency (using jumpers + potentiometers) - 20x40mm footprint, 3mm mounting holes ## Images ![[initeq] 2-Pack NE555 555 Timer Breakout Module Adjustable Square Wave Pulse Generator Shield - Image 1](https://m.media-amazon.com/images/I/81JezLbhq7L.jpg) ![[initeq] 2-Pack NE555 555 Timer Breakout Module Adjustable Square Wave Pulse Generator Shield - Image 2](https://m.media-amazon.com/images/I/71gGrDfGyyL.jpg) ![[initeq] 2-Pack NE555 555 Timer Breakout Module Adjustable Square Wave Pulse Generator Shield - Image 3](https://m.media-amazon.com/images/I/71UqU2PCCjL.jpg) ![[initeq] 2-Pack NE555 555 Timer Breakout Module Adjustable Square Wave Pulse Generator Shield - Image 4](https://m.media-amazon.com/images/I/81oTRsOrFUL.jpg) ![[initeq] 2-Pack NE555 555 Timer Breakout Module Adjustable Square Wave Pulse Generator Shield - Image 5](https://m.media-amazon.com/images/I/81zNSS2SkLL.jpg) --- ## 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.pt/products/67138557-initeq-2-pack-ne555-555-timer-breakout-module-adjustable-square](https://www.desertcart.pt/products/67138557-initeq-2-pack-ne555-555-timer-breakout-module-adjustable-square) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
