This disclosure describes scalable techniques to locate and retrieve inventory items or components from an inventory. Remote modules are co-located with inventory containers and deployed in a warehouse. The remote modules are constructed from low-cost, off-the-shelf equipment and communicate wirelessly with a central server. The central server publishes wirelessly a list of inventory items to remote modules. The module displays the number of items to be picked up using, e.g., color-coded and/or seven-segment LED displays. Once a worker picks up or places an item from a container, the corresponding remote module updates the count of items and returns status to the central server.
