The only-chip wi-fi Digital Paper Show resolution makes use of Wi-Fi expertise, permitting simple updates by way of distant upkeep in IoT purposes.
Wi-Fi-enabledWi-Fi Digital Paper Shows (EPDs) are more and more essential in right now’s digital panorama, providing vital benefits that meet the calls for of contemporary expertise purposes. These shows mix low energy consumption—utilizing vitality solely throughout content material updates—with the flexibility to remotely change show content material, making them preferrred for numerous purposes corresponding to retail signage, data boards, and shopper units like e-readers. Built-in into the Web of Issues (IoT) ecosystem, these shows can talk with different units to supply well timed and dynamic content material updates, enhancing operational effectivity and person expertise whereas supporting environmental sustainability by decreasing paper use. The reference design from Texas Devices (TI) showcases a single-chip resolution for a wi-fi Digital Paper Show (EPD) utilizing Wi-Fi expertise.
EPD shows, recognized for his or her low-power wants, require a means for customers to replace show data simply. This technique permits person management by way of distant upkeep, a vital function within the increasing Industrial Web of Issues (IoT) market. The design incorporates the low-power TI SimpleLink Wi-Fi CC3200 wi-fi MCU, which helps operation on two AA batteries for a number of months to over a 12 months, relying on utilization. Geared up with an built-in microcontroller and Wi-Fi community processor, this CC3200-based design facilitates EPD show administration remotely or domestically by way of the MQTT protocol.
The design’s featured purposes embody digital shelf labels, identify tags, indoor signage, and wearables. These numerous makes use of spotlight the expertise’s versatility and flexibility in numerous settings, from retail environments to non-public identification and indoor directional aids.
The reference design boasts a number of key options, together with low energy consumption appropriate for battery-powered operations, cloud connectivity for distant administration, and native management for on-site changes. It helps 5 completely different show sizes and permits for customized graphics, enhancing visible enchantment and flexibility. Moreover, it affords a broadcast content material possibility, enabling simultaneous updates throughout a number of shows.
Customers can replace a number of EPD panels for distant operations, no matter their bodily location or dimension, by assigning them the identical identifier. This function is especially precious in situations corresponding to digital shelf labelling, the place pricing data must be up to date throughout a number of areas concurrently.
From an influence administration standpoint, this design leverages a key benefit of EPD expertise—no energy consumption between updates. The SimpleLink system can preserve a continuing connection for rapid response updates or intermittently at set intervals to minimise energy utilization and lengthen battery life. The CC3200’s Cortex M4 MCU drives the EPD show shortly and effectively, guaranteeing fast updates and contributing to the system’s general low energy consumption.
TI has examined this reference design. It comes with a invoice of supplies (BOM), schematics, meeting drawing, printed circuit board (PCB) structure, and extra.
