It measures bidirectional current up to ±31 A with a proportional analogue voltage output centred at Vcc/2. The sensor offers a very low resistance current path (~0.6 mΩ) and electrical isolation up to 100 V. Operating from 3 V to 5.5 V, the board interfaces directly with both 3.3 V and 5 V systems without level shifting. Key Features Current Range – ±31 A bidirectional Sensor – Allegro ACS711EX Hall effect linear current sensor Low Resistance – ~0.6 mΩ current path for minimal insertion loss Electrical Isolation – Up to 100 V between current path and sensor output Output – Proportional analogue voltage centred at Vcc/2, typical error ±4% Supply Voltage – 3 V to 5.5 V (compatible with 3.3 V and 5 V systems) Overcurrent Fault Output – Dedicated fault pin for protection circuits Ideal For Motor current monitoring Overcurrent protection circuits Battery charging systems Power supply monitoring Also Available ACS712 Current Sensor – 20 A ACS712 Current Sensor – 5 A Package Contents 1× ACS711EX Current Sensor Carrier Board **Product Type:** physical ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCb4BJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--e6bcbf129b3ae7a7d67b8e4d4879404dbbd54dbd/image_f06eb52f-f3a0-456e-8255-fd2f45a41540.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCcIBJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--a4bb7ec149ec749013fb7194b73ead5bd24d1517/image_84f59c5e-4861-4ae0-8415-535c545b2fd6.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCcYBJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--cbd950842195a31421cef924b56fb6826de7de76/image_8d209bc2-329f-4270-8939-facce613bdbc.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCcoBJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--d40a6d14282bcb84429e6c3436843ae6b836066d/image_ab1a39ac-0aa8-4a02-83f9-b5933a348a6e.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCc4BJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--5a5f9e10adaa4a2f031aaa391c2f42e16595f631/image_65d361e3-59d2-4f77-9ba9-8e2c70fdc016.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCdIBJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--5e16c733732fa87557e3543fbb475de64024b8c7/image_345186ae-4cc2-49c3-b25c-93793cb1fe2a.jpg) - [Image 7](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCdYBJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--8cb6fa48798c48d7259a53c79193d5b105184053/image_8fcb51c5-62e0-4be6-b832-f87d775b5ef8.jpg) - [Image 8](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCdoBJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--d1f98410fe72b902ce170f0b27f0658458c02b74/image_bc4a6d89-5569-450b-85fe-1c477c2ce906.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
